Correcting Color Blindness With Glasses

Numbers hidden in patterns - an eye test for color blindnessMillions of Americans contend with color blindness every day; around 8 percent of men and .5 percent of women of Northern European descent. Can you picture what life would be like if you couldn't see the color variations of a beautiful sunset? It's the reality of those living with color blindness. However, advances in technology have led to the creation of special glasses that can correct the disability. The most typical form of the condition, which prevents men and women from distinguishing between specific colors, is red-green color blindness. 

"In the retina, there are two types of cells that detect light," author David Turbert explains. "They are called rods and cones. Rods detect only light and dark and are very sensitive to low light levels. Cone cells detect color and are concentrated near the center of your vision. There are three types of cones that see color: red, green, and blue. The brain uses input from these cone cells to determine our color perception."

Planning A Wedding While Blind

A couple stand in a doorway dressed for their weddingThe most special day of one's life for the majority of adults is understandably their wedding day. Naturally, preparing for such an event is demanding and stressful; everyone wants to get hitched without any hitches. You want everything to be perfect from the catering to the cake, which can take hundreds of hours of preparation. Planning a wedding is challenging enough, now imagine having to organize it while living with blindness.

A childhood accident led to juvenile idiopathic arthritis, explains Sassy. Initially, the problem only impacted her life physically. However, arthritis can affect one's vision; Sassy's condition resulted in blindness. Nevertheless, Sassy would not be deterred from planning her special day. Sassy says:

"My doctor warned me that the arthritis could affect my sight in the future – it attacks organs as well as joints – so every six months I went for a check-up. I first noticed my vision was blurring in 2007, and my eyes became inflamed and watery."

If you are living with blindness or vision loss in Southern California, please contact San Diego Center for the Blind.

Visually Impaired Artist Shares Her Story

visually impaired artist sits on a couch beside a reflective half-wallCOVID-19 has changed the lives of billions of people in a myriad of ways. All of us have been impacted in one way or another—both in good ways and bad. For artist Sandy Goldberg, whose vision loss in the right eye changes how she sees the world, the pandemic has helped her to be okay with embracing her condition publicly.  

Most people see the world in three dimensions. However, having visual impairment in one eye can cause one only to see things in two dimensions or flat. Goldberg is one of those people. She was born with no vision in her right eye. She was always inclined to keep her 2D reality from her curators, but the Coronavirus pandemic has changed her opinion on the matter.

"I think if I revealed it, people would see it maybe as a disability," said Goldberg. "I'm supposed to help others to see when they could mistakenly think I can't see myself."

At SDCB, we offer many programs and services to improve the lives of men and women living with vision loss. Please reach out to us to learn more.

Exercise and Vision Loss Prevention

Woman in a kayak looking towards mountains in the distanceStaying healthy can be achieved by eating right and regular exercise. While Americans are mostly unable to get to the gym these days owing to the COVID-19 outbreak, there are many ways you can stay fit at home and outdoors. Adopting an exercise routine may help protect against vision loss as well.

Researchers at the University of Virginia have sought to better understand the link between exercise and vision loss prevention. Professor Bradley Gelfand studies how a little bit of exercise can protect against the number one cause of vision loss in America—macular degeneration. Ten million Americans are estimated to have macular degeneration. 

"We had two experimental groups. One group had access to exercise ad libitum, or as much as the subject wanted. And another group did not have access to an exercise wheel," said Gelfand.

Please contact San Diego Center for the Blind if you are struggling with macular degeneration or any other type of vision loss. We offer several services and programs that can improve your quality of life.

A new Children's Book on Blindness

An image from the book on blindness described in article.The majority of children, naturally, know very little about disabilities. Ignorance can lead young people to mistreat other youngsters who are living with hearing, vision loss and blindness. Author Andrew Stoner decided to take it upon himself to help kids better understand what it's like to live with blindness.

Stoner's new children's book, "Mr. Lollypop Makes A Friend," is a children's book about Mr. Flapjack Lollypop. The protagonist helps a cat named Rufus, a feline that he believes is blind and needs help. Stoner knows what it's like to live with blindness because he is blind.

"I walk around with a white cane and everyone can tell I'm blind," Stoner said. "I get all sorts of questions about my blindness and about how I go about my everyday life so I thought this was a good way to let people know what it's like."

Methanol Poisoning Can Lead to Blindness

Hand sanitizer pumped into a bare hand can cause blindness in rare case it contains methanolWarning: methanol can be toxic to humans when ingested, inhaled, and absorbed through the skin. During a global pandemic that involves a potentially deadly virus, it's vital to wash or sanitize your hands regularly. Safe and effective hand sanitizers contain 60 percent or more of isopropyl alcohol.

Unfortunately, a company is making hand sanitizers with methanol. The Mexico-based Eskbiochem SA de CV sells nine types of sanitizers containing methanol that are harmful to unsuspecting users. Toxic levels of methanol can cause blindness. The U.S. Food and Drug Administration (FDA) issued an advisory to consumers to avoid methanol-based hand sanitizers.

"Methanol is not an acceptable ingredient for hand sanitizers," the FDA wrote. With use of hand sanitizers at a high amid the COVID-19 pandemic, the agency advised that anyone who has used the methanol-containing products "seek immediate treatment, which is critical for potential reversal of toxic effects of methanol poisoning."

Contact Lens Care

Contact Lens Care Essential to Eye Health

A contact lens on a woman's outstretched handWith approximately 45 million Americans wearing contact lenses, it's scary to think that many haven't been told proper care information, or, at least, they haven't properly heard and absorbed it. 

One-third of contact wearers over the age of 18 don't remember ever being given care information for their eyes and contacts. Nearly 20% remember only very minimal information. Yet, the majority of care providers say they give the needed instructions on a regular basis. 

What are the important care tips everyone needs to know?
  1. Always wash and dry hands before handling contact lenses
  2. For reusable lenses, always wash and store as dictated by doctor or provider
  3. Store lenses in the proper case, wash case between uses and allow to dry
  4. Use only products to clean and store lenses that are recommended for that purpose
  5. Maintain regular appointments

Diet and Age-Related Macular Degeneration 

Macular Degeneration causes linked to diet, healthy breakfast pictured here Previous studies have shown fruit and vegetables high in vitamins and other nutrients can be good for your eyes and your vision, just as they are good for most other parts of your body!

Now, a new study tackles the issue of whether some foods may be bad for your eyes; specifically, it tackles if food choices impact the progression of AMD.

It may come as no surprise that researchers found a correlation between diets that are high in red meat, fried foods, dairy and refined grains and the progression of AMD. They did not find a correlation between these foods and early stage AMD. From this, it appears that these foods may worsen progress, but don't have an impact on developing AMD initially.

Childhood Glaucoma Needs Early Intervention

A doctor examines a child's eyesSadly, millions of children worldwide face vision loss and blindness; in a large number of cases, babies are born without the gift of sight. While glaucoma is most commonly associated with adults, children are impacted by the condition as well. In such cases, treatment is vital because permanent vision loss can result from amblyopia and corneal scarring.

Early diagnosis is vital owing to the fact that children can lose vision quickly from glaucoma. However, if treatment is successfully performed early enough, vision loss can be averted.

Eye App Helps Early Detection 

A doctor examines a patient's eyeDiabetes is one of the leading causes of blindness on the planet. In fact, the condition is the number one cause of new blindness in working-age adults. Early detection is key to preventing further problems. According to the National Eye Institute, diabetic retinopathy affects between 40 and 45 percent of American diabetics.

Diabetic retinopathy impacts the lives of many people in developing countries, which is why researchers have been seeking inexpensive solutions for early diagnosis. Researchers found that a special adapter for built-in smartphone cameras to image the retina produced the most precise view.

"The best result in our test was achieved by an adapter with an additional lens that is attached to the smartphone," says Dr. Maximilian Wintergerst from the Department of Ophthalmology at the University Hospital Bonn. "It allowed almost 80 percent of eyes with any retinal changes to be detected, even in the early stages. Advanced damage could even be diagnosed 100 percent of the time."

Vision Loss and Diabetes Can Go Hand-In-Hand

Vision Loss and Diabetes too often go togetherType-2 diabetes and vision loss often go hand-in-hand. It's a complicated disease that can be fatal if it isn't carefully monitored. A group of researchers wondered: "Could vision loss and the visual disturbances that diabetes patients experience be prevented?"

A 4-year study was conducted to assess the cumulative incidence of visual impairment and blindness and their determinants in well-characterized community-based people with type 2 diabetes. The researchers found that avoiding hypoglycemia may prevent vision loss among individuals with type 2 diabetes, preserving kidney function may prevent vision loss among individuals with type 2 diabetes, and smoking cessation may prevent vision loss among individuals with type 2 diabetes.

AMD-Research Promising

AMD-Research looks at new possibilities for eye careAge-related macular degeneration impacts the lives of millions of people around the globe. Vision loss is caused by inflammation in the eye that leads to excessive growth of blood vessels in the retina. Current therapies to slow the process are anti-VEGF therapies such as Regeneron and Bayer's Eylea.

A new study shows that Sanofi and Regeneron's drug Dupixent could be useful in treating AMD. The research team contends that immune molecule interleukin-4 (IL-4) and its receptor—which Dupixent inhibits—may be promising for those living with macular degeneration. IL-4 is known to inhibit the formation of new blood vessels.

"Our results show that IL-4 plays a crucial role in excessive blood-vessel growth by recruiting bone marrow cells that aid this growth to the lesion in the eye," said Takashi Baba, the study's co-first author.

Early Macular Degeneration Treatment Important

An image illustrating doctors looking at Early Macular Degeneration TreatmentAge-related macular degeneration (AMD) is a progressive eye disease that affects older men and women, specifically those above the age of 50. AMD is the common cause of irreversible vision loss among the elderly; the condition impacts the retina, the part of the eye responsible for central vision and sharpness.

Naturally, early detection of macular degeneration is critical; unfortunately, GlobalData epidemiologists found that less than half of AMD cases were diagnosed in 2019. This is not a novel phenomenon. A 2017 study published in JAMA Ophthalmology showed that a significant number of AMD cases go undetected and undiagnosed in the primary eye care setting.

Primary eye care doctors require better training on how to assess and diagnose AMD accurately.

Google's Diabetic Blindness Detection Not Effective

Google is a global leader in innovation, and while they are most known for their search engine, the company creates several other devices to make our lives easier. In recent years Google has been working on and was able to create an artificial intelligence (AI) device to detect diabetic blindness early. The AI worked excellently in tests (90 percent accuracy in the lab); however, it proved to be less effective in the real world. 

The device was created to speed up diagnosis for diabetic blindness, from 10 weeks to 10 minutes. Unfortunately, the AI didn’t perform well at 11 clinics in Thailand. The theory behind the reduced efficacy is because the AI was trained on high-resolution images. It was discovered that the nurses in Thailand often had to scan dozens of patients quickly, and they did so in poor lighting conditions, which did not produce high-resolution images. The result was the AI rejecting over a fifth of the images. Google wrote that they still have to “study and incorporate real-life evaluations” before the AI can be widely deployed, adding:

“Since this research, we have begun to hold participatory design workshops with nurses, potential camera operators, and retinal specialists (the doctor who would receive referred patients from the system) at future deployment sites. Clinicians are designing new workflows that involve the system and are proactively identifying potential barriers to implementation.”

New Treatment for Diabetic Retinopathy

Millions of people around the globe contend with Type II diabetes, a condition that can result in a number of health complications, including vision loss and blindness. However, a new study indicates that a possible treatment showed anti-inflammatory and neuroprotective effects on the retina and optic nerve head. The findings, appearing in The American Journal of Pathology, showed promising results with type 2 diabetic retinopathy using animal models. The treatment

involves the use of Glucagon-Like Peptide Receptor Agonist Lixisenatide.


“Inflammation causes neurodegeneration as well as microvascular abnormalities in the retina,” explained lead investigator Jin A. Choi, Ph.D., Department of Ophthalmology and Visual Science, St. Vincent’s Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea. “Diabetic retinal neurodegeneration can occur before the onset of clinical diabetic retinal microvascular abnormalities. Therefore, therapeutics for neurodegeneration may provide a novel interventional strategy in the window period between the diagnosis of type 2 diabetes and the onset of clinically manifested diabetic retinopathy.”

Study on Retinopathy of Prematurity

An image of a baby who could benefit from new research into Retinopathy of Prematurity One of the challenges that premature babies face involves the eyes. A condition called retinopathy of prematurity (ROP) is an eye disorder that is one of the leading causes of blindness in children. However, treatment can prevent blindness in premature babies. 

A study conducted by the Pediatric Eye Disease Investigator Group (PEDIG) and supported by the National Eye Institute (NEI), part of the National Institutes of Health, showed that a lower dose of a drug used to treat ROP could be more effective in preventing infant blindness. The drug is called Avastin (bevacizumab). The findings were published in JAMA Ophthalmology. 

"In the current study, we found that 0.004 mg of Avastin – a dose that's merely 0.6% of the dose used in the 2011 study of Avastin for ROP – may be the lower limit to be effective for most infants with ROP," said the new study's protocol chair, David Wallace, M.D., MPH, chair of ophthalmology at the Indiana University School of Medicine. The findings set the stage for a randomized controlled trial comparing long-term effects of low-dose Avastin with laser therapy for treating ROP."

Eye Disease Research on Leaky Vessels

A new study shows why people living with an eye disease have leaky vessels and harmful swelling in their eyes. The findings could be a stepping-stone to the discovery of more effective treatments for various types of eye disease, including age-related macular degeneration (AMD) and diabetic retinopathy. The researchers report that eye conditions that result in leaky blood vessels result in harmful swelling and progressive vision loss.

"Our findings provide an answer to the questions on how blood vessels leak and show that leakage can be stopped without killing the blood vessels," concludes senior author Lena Claesson-Welsh, Professor at the Department of Immunology, Genetics and Pathology, Uppsala University. "Using this insight, we've begun testing drugs that could selectively block this leak-inducing step in the process. If this approach is effective, it could lead to new treatments that stop leaking without the harmful side effects of existing drugs."

Prevention of Common Eye Diseases

Sadly, not every eye disease can be prevented, and over 150 million Americans are living with a form of correctable vision loss, according to the American Academy of Ophthalmology. However, you can take actions today that can protect your vision and avoid complications down the road.

For instance, you can delay the development of cataracts if you buy 100 percent UV-blocking sunglasses. They can stave off retinal damage. An unhealthy diet and smoking tobacco can also negatively impact your vision. Researchers indicate that people whose diets include higher levels of vitamins C and E, zinc, lutein, zeaxanthin, omega-3 fatty acids DHA and EPA are less likely to develop AMD. The AAO reports that smoking is directly linked to age-related macular degeneration.

New Medications For Glaucoma?

A graphic with glaucoma written at the centerGlaucoma is the leading cause of irreversible blindness in America. The condition is caused by ocular hypertension; it damages the optic nerve resulting in vision loss. There is no known cure, but there are pharmacologic therapies and some invasive. One drug, latanoprost, is a standard first-line treatment for those newly diagnosed with glaucoma. However, the first line of defense does not mean it is the most effective treatment necessarily. 

Two new classes of drugs approved by the FDA have been introduced for the treatment of open-angle glaucoma—latanoprostene bunod and netarsudil. Using them in conjunction with previous medications could improve patient outcomes.

"What is unique about the netarsudil/latanoprost combination is this is really one of the first times we actually had a medicine go up against latanoprost alone," said Joseph F. Panarelli, MD, associate professor in the Department of Ophthalmology at NYU Langone Medical Center. "Latanoprost is one of our bigger guns out there, so it is encouraging to see that we have these new medicines, and it's nice to see data that does support good efficacy with these different agents."

An image of the blind teacher who died of COVID astride a camelBrian R. Miller, 52, was born with defective retinas and could barely see large text right in front of his face. Nevertheless, he was one of the first blind students to sit in classrooms with sighted students in California in the 1970s and 1980s.

Miller's blindness led him to dedicate his life to helping other students with disabilities. After high school, he went on to a career with the U.S. Education Department's Rehabilitation Services Administration to help others like him. Sadly, his life was cut short due to complications related to COVID-19.

Miller started exhibiting symptoms in mid-March, after returning from a trip to Jordan; in his life, he visited 45 states and 65 countries. He entered the hospital on March 28th, was put on a ventilator the next day, and died after he began bleeding internally and suffered organ failure.

"Brian believed strongly in the capacity of individuals with disabilities to engage in all aspects of life," Carol Dobak wrote in a message to department staff, Miller's direct supervisor, "and his own life was a reflection of this philosophy."

Cataract Surgery Required For Savannah Guthrie

A close up of Savannah Guthrie who must have cataract surgery A short time ago, we wrote to you about an unfortunate accident involving a toy train and TODAY's Savannah Guthrie resulting in vision loss. Even though she had surgery to repair the damage, sadly, her vision is still "not great." 

While playing with her three-year-old son Charlie, the youngster accidentally hit his mother in the eye, which left a tear in her retina. Since her eyesight has not improved, she will have to have more operations, including cataract surgery. 

"When you have this retinal detachment, most people will end up developing cataracts, obviously at a much younger age than would normally be expected," she explained. "When you have cataracts, you get blurry spots and you notice it more and more. So I do."

Please contact San Diego Center for the Blind if you'd like to learn more about our visual rehabilitation programs and services.

Louis Braille Prize Announced

Louis Braille prize award recipients picturedAmid the coronavirus pandemic it's helpful to receive some uplifting news from time to time. Lisa Dalton was honored this month with the Louis Braille Touch of Genius Prize for Innovation. She created reusable braille labels ("CanDo" labels) because her former boyfriend is blind. Dalton wanted to help him find things in food cabinets. Lisa founded Candoables, a company that uses 3-D printers to make Braille "CanDo" labels. 

"CanDo labels are already having an impact on the blind and visually impaired community," Brian Mac Donald, president of the National Braille Press, said in the release. "These reusable labels will help significantly in keeping areas such as the pantry or refrigerator organized."

Google Launches Virtual Braille Keyboard for Android

An illustration of the new Android Braille KeyboardAt least 2.2 billion people globally have a vision impairment or blindness, reports the World Health Organization (WHO). In response to those staggering numbers, the tech giant Google is launching a virtual braille keyboard for Android smartphones, which will help those who are living with low vision or blindness. Such individuals will be able to type without any additional hardware. 

Google worked together with braille developers and users to design a keyboard that can be used anywhere—social media, text messaging, and email apps. Here's how it works: the keyboard uses a standard 6-key layout, and each key represents one of 6 braille dots, which, when tapped, make any letter or symbol. A user will tap dot 1 to type the letter A, tap dots 1 and 2 to type the letter B, tap dots 1 and 4 to type the letter C, tap dots 1, 4, and 5 to type the letter D, and so on.

"Today, braille displays make typing accessible on most phones and computers through a physical braille keyboard. But it can be time-consuming to connect an external device each time you want to type something quickly on your phone," wrote Android Accessibility product manager Brian Kemler in a blog post. "As part of our mission to make the world's information universally accessible, we hope this keyboard can broadly expand braille literacy and exposure among blind and low vision people."

iPhone Makes Blind Photography Easier

iPhone wants to make blind photography easier and illustrates how it will work in this sketchTaking photographs is a part of life; they are how we preserve our memories. However, for people living with vision loss and blindness, their conditions make snapping pictures a real challenge. Apple plans to make it easier for the visually impaired to take photos.

"[The iPhone may provide] an audible description of the scene," says the patent. "[The] audible description includes information that corresponds to the plurality of objects as a whole (e.g., 'Two people in the lower right corner of the screen,' or 'Two faces near the camera')."

Please reach out to SDCB if you require assistance with vision loss or blindness. We offer many programs that can help.

Warning: Eyes are Portals for Coronavirus Transmission

A man has his eyes checked - eyes can be involved in coronavirus transmissionCOVID-19 – the coronavirus quickly spreading around the world – has infected 1,288,372 people and taken 70,482 lives. It's essential that you understand the ways you can contract the potentially deadly virus. Dr. Bruce Miller, an ophthalmologist, wants men and women to be aware that the eyes can be doorways for the pathogen. It's vital to keep your fingers away from your eyes. If you wear contacts, then start using your eyeglasses again.

"A small percentage of people who test positive for the coronavirus has an associated pink eye or conjunctivitis," Miller says. He adds that, "your doctors are here either at home or via telemedicine, to answer your questions and to get you through this."

San Diego Center for the Blind offers vision rehabilitation services. Please reach out to learn how we can help you or a loved one.

Glasses Vs. Contacts During Pandemic

The Coronavirus impacts safety of glasses vs contactsThe COVID-19 pandemic is changing everyone's life in a myriad of ways. Those living with low vision or vision loss can benefit from taking out their contacts and putting their glasses back on. Doing so can help prevent the spread of the virus. The American Academy of Ophthalmology says it can help you stop touching your face.

"You rub your eyes, then rub your face, scratch your face, put your fingers in your mouth, put your fingers in your nose," said Dr. Thomas Steinemann, a clinical spokesperson for the American Academy of Ophthalmology. "Some people are not very hygienic and may have forgotten to first wash their hands."

San Diego Center for the Blind can assist you or a loved one with vision loss. Please contact us to learn more.

New Phonetics For Blind Singers

Blind Singers now learn enunciation with braille phoneticsEarlier in the week, we wrote about Louis Braille and how he made adaptations for music and mathematics by adding extra symbols. Now, a professor at Vanderbilt University is helping blind aspiring classical singers pronounce lyrics. Cherie Montgomery, a voice professor, has created a new braille phonetic system.

Lacking the resources to teach a student lyric diction, Montgomery found a solution. She published a textbook, "Singer's Diction for Braille Readers," which includes a phonetic chart with visual and tactile symbols.

"[With the chart,] teachers can point to a symbol and say this is the sound you're making [and] I would like to hear for example this sound..." she said.

Please contact SDCB if you are struggling with vision loss and would like to have more independence.

New Contacts for Color Blindness

blindnessA new type of contact lens could help people living with color blindness. Researchers say that they could help people with a form of red-green color blindness. The contact lenses restore lost color contrast. The research was published in The Optical Society journal Optics Letters.

"Glasses based on this correction concept are commercially available, however, they are significantly bulkier than contact lenses," said Sharon Karepov, a member of the research team, said. "Because the proposed optical element is ultrathin and can be embedded into any rigid contact lens, both deuteranomaly and other vision disorders such as refractive errors can be treated within a single contact lens."

Contact SDCB if you are struggling with vision loss, we have several programs that can help.

The Wonders of Braille
BrailleLouis Braille invented a tactile reading method for blind people in 1829. It enabled people who are living with blindness to read and write. Using Captain Charles Barbier’s “night writing” system, Braille made simplifications to Barbier’s 12 dot system. He reduced it to six dots.

Louis Braille’s six dot method for tactile reading and writing should not be confused with a language; it’s instead a code for reading and writing in every language. He even made adaptations for music and mathematics by merely adding extra symbols.

We invite you to contact SDCB if you are experiencing vision loss.

Protecting Against Vision Loss
vision lossRegular eye exams can prevent you from experiencing vision loss. During Save Your Vision Month, we would like to encourage you to prioritize your eye health. Naturally, the American Optometric Association would like you to do the same. Annual eye exams are essential!

“A lot of people view vision as very important, and would be very unhappy if they lost any part of their vision, but yet they don’t require much maintenance so therefore it doesn’t enter our thought process but it is an extremely valuable tool that we need to start taking better care of, and that is why we recommend those yearly eye exams for those things,” says Dr. Bill Holec, an Optometry Specialist. “We are always better catching things at an early stage rather than a later stage.”

Please reach out to SDCB if you require assistance with vision loss.

Older Americans at Significant Risk of Vision Loss
vision lossThe number of older Americans at high risk for vision loss rose from 65 million to 93 million between 2002 and 2017, according to federal data. This news is concerning and should prompt more older people to get regular eye tests. The research appearing in JAMA Ophthalmology shows that those at significant risk of losing their sight include people with diabetes and anyone with eye or vision problems.

"The number of adults at high risk for vision loss is high and may continue to increase in the coming years with the increasing population of adults over 65 years and prevalence of diabetes," said study lead author Sharon Saydah, a senior scientist at the U.S. Centers for Disease Control and Prevention (CDC).

Please reach out to San Diego Center for the Blind if your life is impacted by vision loss.
