World Sight Day 2017
Happy World Sight Day! Did you know that 80% of the world’s vision impairment is treatable and preventable? World Sight Day (#WSD) is an annual day of awareness held on the second Thursday of October, to focus global attention on blindness and vision impairment.
9 Facts About Vision Impairment:
- Approximately 285 million people worldwide live with low vision and blindness
- Of these, 39 million people are blind and 246 million have moderate or severe visual impairment
- 90% of blind people live in low-income countries
- Yet 80% of visual impairment is avoidable – i.e. readily treatable and/or preventable
- Restorations of sight, and blindness prevention strategies are among the most cost-effective interventions in health care
- The number of people blind from infectious causes has greatly reduced in the past 20 years
- An estimated 19 million children are visually impaired
- About 65 % of all people who are visually impaired are aged 50 and older, while this age group comprises only 20% of the world’s population
- Increasing elderly populations in many countries mean that more people will be at risk of age-related visual impairment
Healthy vision is critical to fully experiencing the world around us, and World Sight Day is a reminder of the importance of scheduling regular eye exams for yourself and your loved ones. If your family is due for their annual check-up, please call our West Hollywood office at (323) 656-9550, or reach out via our Contact Page. Our experienced optometrists look forwarding to welcoming you.
Diabetes Symptoms: How Does Diabetes Affect Your Eyes?
Diabetes mellitus (DM) causes abnormal changes in the blood sugar (glucose) that your body ordinarily converts into energy to fuel different bodily functions.
Uncontrolled diabetes allows unusually high levels of blood sugar (hyperglycemia) to accumulate in blood vessels, causing damage that hampers or alters blood flow to your body’s organs — including your eyes.
Diabetes generally is classified as two types:
- Type 1 diabetes. Insulin is a natural hormone that helps regulate the levels of blood sugar needed to help “feed” your body. When you are diagnosed with type 1 diabetes, you are considered insulin-dependent because you will need injections or other medications to supply the insulin your body is unable to produce on its own. When you don’t produce enough of your own insulin, your blood sugar is unregulated and levels are too high.
- Type 2 diabetes. When you are diagnosed with type 2 diabetes, you generally are considered non-insulin-dependent or insulin-resistant. With this type of diabetes, you produce enough insulin but your body is unable to make proper use of it. Your body then compensates by producing even more insulin, which can cause an accompanying abnormal increase in blood sugar levels.
With both types of diabetes, abnormal spikes in blood sugar increase your risk of diabetic retinopathy.
Eye damage occurs when chronically high amounts of blood sugar begin to clog or damage blood vessels within the eye’s retina, which contains light-sensitive cells (photoreceptors) necessary for good vision.

The Consequences of Undetected and Untreated Vision Problems
Children with undetected vision problems are sometimes inaccurately diagnosed with attention deficit disorder (ADD) or attention deficit hyperactivity disorder (ADHD). When vision is difficult, it requires greater effort than normal, leading the child to avoid close work. It may appear the child is daydreaming
Many children with undetected vision problems struggle in the classroom. These symptoms include:
- Trouble finishing written assignments
- Losing their place when reading
- A short attention span when doing close work
- Skipping words when reading
- Having greater potential than grades may indicate
If your child appears to be experiencing any of these symptoms, call our office at (323) 656-9550 for a complete eye examination with one of our trusted Los Angeles eye doctors today!
Ask Your Eye Doctor: What is “Good Vision”?
To test for good vision includes measuring visual acuity, the ability of the eyes to see and distinguish fine details. In addition to visual acuity, visual integration must also be checked. This is the ability to process and integrate visual information so we can understand what we see. Other visual skills such as eye teaming (the ability of the eyes to work properly together), eye focusing (the ability of the eyes to easily focus and shift focus to near and distant points), and eye motility (the eyes ability to move together) must also be tested, along with checking eye health.
Good vision includes all of these visual components working well together. Vision screenings done at the pediatricians office and at school are very helpful, but is not a substitute for a comprehensive eye examination. If your child struggling in class, it could be due simply to an undetected vision problem.

How Important is Good Vision to Learning?
Good vision is an important part of education. Many experts believe 80 percent of learning is done through a child’s eyes. Reading, computer usage, and chalkboard work are all visual tasks students perform every day. A child’s eyes are always in use in the classroom. Therefore, when they’re not working properly, learning and class participation will suffer.

June is Cataract Awareness Month
Summer is just around the corner, and the importance of understanding ultraviolet light and the effects it could have on the eyes; including inducing cataracts, is much more essential. So what exactly are cataracts? A cataract is a general term for any kind of clouding of the eye’s natural lens, which sits behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40, and is the principal cause of blindness in the world. In fact, there are more cases of cataracts worldwide than there are of glaucoma, macular degeneration, and diabetic retinopathy combined.
A cataract starts out small and at first has little effect on your vision. You may notice that your vision is blurred a little, like looking through a cloudy or dirty window. A cataract may make light from the sun or a lamp seem too bright or glaring. Or you may notice when you drive at night that the oncoming headlights cause more glare than before. Colors may not appear as bright as they once did.
The lens inside the eye works much like a camera lens, focusing light onto the retina, similar to the film inside a camera. It adjusts the eye’s focus, letting us see things clearly both up close and far away. The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.
No one knows for sure why the eye’s lens changes as we age, forming cataracts. Researchers are gradually identifying factors that may cause cataracts — and information that may help to prevent them. Many studies suggest that exposure to ultraviolet light is associated with cataract development, which is why the importance of UV protective sunglasses and wide brimmed hats are emphasized. Other studies suggest people with diabetes are at risk for developing a cataract. Other risk factors include cigarette smoke, air pollution and heavy alcohol and/or salt consumption.

May is Ultraviolet Awareness Month
Did you know ultraviolet (UV) and other radiation from the sun can harm your eyes?
Extended exposure to the sun’s UV rays has been linked to eye damage, including cataracts, macular degeneration, pingueculae and pterygia and photokeratitis that can cause temporary vision loss.
New research suggests the sun’s high-energy visible (HEV) radiation — also called “blue light“ — may increase your long-term risk of macular degeneration. People with low blood plasma levels of vitamin C and other antioxidants especially appear at risk of retinal damage from HEV radiation.
To protect your eyes from harmful solar radiation, sunglasses (tinted) or clear lens glasses should be coated with UV filters which block 100 percent of UV rays and also absorb most HEV rays. Frames with a close-fitting wraparound style provide the best protection because they limit how much stray sunlight reaches your eyes from above and beyond the periphery of your sunglass lenses.
Anyone who spends time outdoors, especially around water, sand or snow, is at risk for eye problems from UV radiation. Risks of eye damage from UV and HEV exposure change from day to day and depend on a number of factors, including:
- Geographic location. UV levels are greater in tropical areas near the earth’s equator. The farther you are from the equator, the smaller your risk.
- Altitude. UV levels are greater at higher altitudes.
- Time of day. UV and HEV levels are greater when the sun is high in the sky, typically from 10 a.m. to 2 p.m.
- Setting. UV and HEV levels are greater in wide open spaces, especially when highly reflective surfaces are present, like snow and sand. In fact, UV exposure can nearly double when UV rays are reflected from the snow. UV exposure is less likely in urban settings, where tall buildings shade the streets.
- Medications. Certain medications, such as tetracycline, sulfa drugs, birth control pills, diuretics and tranquilizers, can increase your body’s sensitivity to UV and HEV radiation.
Surprisingly, cloud cover doesn’t affect UV levels significantly. Your risk of UV exposure can be quite high even on hazy or overcast days. This is because UV is invisible radiation, not visible light, and can penetrate clouds.
The risk of damage to our eyes and skin from solar UV radiation is cumulative, meaning the danger continues to grow as we spend time in the sun throughout our lifetime. With this in mind, it’s especially important for kids to protect their eyes from the sun. Children generally spend much more time outdoors than adults. In fact, experts say nearly 50 percent (or more) of our lifetime exposure to UV rays may occur by age 18, given that many children spend significantly more time outdoors than the average adult. Therefore, make sure your kids’ eyes are protected from the sun with good quality sunglasses. Also, encourage your child to wear a hat on sunny days to further reduce UV exposure.
Come see us to get fitted for the perfect pair of prescription or non-prescription sunglasses to help protect your eyes from the sun (without sacrificing style). Schedule an appointment with our office by calling (323) 656-9550. Our optometrists look forward to seeing you!

January is National Glaucoma Awareness Month
What IS glaucoma? Glaucoma is a group of eye diseases that gradually steal sight without warning. It is often called “the sneak thief of sight” since there are no symptoms and once vision is lost, it’s permanent. Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires. It is responsible for carrying images from the eye to the brain. In the most common form, there are virtually no symptoms. Vision loss begins with peripheral or side vision, so if you have glaucoma, you may not notice anything until significant vision is lost. As much as 40% of vision can be lost without a person noticing.
Glaucoma is the leading cause of preventable blindness. It is the second leading cause of blindness in the world, according to the World Health Organization. Although the most common forms primarily affect the middle-aged and the elderly, glaucoma can affect people of all ages. Those at higher risk include people of African, Asian, and Hispanic descent. Among African American and Latino populations, glaucoma is the leading cause of blindness, and it is more prevalent. Glaucoma is 6 to 8 times more common in African Americans than Caucasians. Other high-risk groups include: people over 60, family members of those already diagnosed, diabetics, and people who are severely nearsighted.
Over 2.2 million Americans, and over 60 million people worldwide, have glaucoma. Experts estimate that half of them don’t know they have it. Combined with our aging population, we can see an epidemic of blindness looming if we don’t raise awareness about the importance of regular eye examinations to preserve vision. Regular eye exams are especially important for those at higher risk for glaucoma, and may help to prevent unnecessary vision loss.
