How you work to achieve certain things has so much to do with your vision. However, many people do have problems with seeing something, thinking about it, and then reacting. These issues can cause delays in everything from fine motor tasks to Simply reading. If you suspect that you have an issue with visual performance, vision performance screenings can help. Take a look at some of the most commonly asked questions about vision performance screening.

What is vision performance screening?

Visual performance grading is a type of test performed by an optometrist who is skilled with visual development and rehabilitation. During the screening, multiple measurements will be taken to determine things like how your eyes truck and team together, how your eyes and brain work together, and even your reading comprehension.

Why is vision performance so important?

Vision performance affects a lot of ordinary tasks most people do every day. If you are driving, playing basketball, or working on an assembly line at work, visual performance is affecting how well you do these tasks. Even though there are certain conditions that can cause delays in visual performance, many people can actually get help from an optometrist to build the neural skills that are associated with how the brain and eyes connect.

Is vision performance training good for adults and children?

Vision performance training can be beneficial for both children and adults, even though it is commonly assumed the training is only for children. It is more common for younger patients to need this form of eye training due to slight developmental delays, but adults can benefit from the training just the same. For instance, if an adult has a difficult time reading and retaining information, it can be extremely beneficial to undergo a vision performance test to find out if there is an issue and then undergo training to help.

Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.

Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.

What is Diabetes?

Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.

How Does Diabetes Affect The Eyes?

Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.

In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.

The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.

Diabetic Retinopathy

As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.

The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.

Signs and Symptoms of Diabetic Retinopathy

The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:

• Blurred or fluctuating vision or vision loss
• Floaters (dark spots or strings that appear to float in your visual field)
• Blind spots
• Color vision loss

There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.

A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.

Retinal Detachment

Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.

Diabetic Macular Edema (DME)

Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.

Treatment for Diabetic Retinopathy and Diabetic Macular Edema

While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.

Prevent Vision Loss from Diabetes

The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

October is World Blindness Awareness Month, an initiative started to help the public to understand the realities of visual impairment and how it affects the world population.

Unfortunately, there are hundreds of millions of individuals around the world who are unnecessarily blind or visually impaired due to causes that are preventable and treatable. Much of this is due to lack of access to proper healthcare and education. Today’s research shows that the leading causes of blindness and moderate and severe vision impairment (MSVI) are uncorrected refractive error, cataracts, age-related macular degeneration (AMD), glaucoma and other retinal diseases such as retinitis pigmentosa.

While steps are being taken to increase education and access to eye care in populations that are known to be lacking, vision impairment is expected to increase threefold by 2050 due to aging and an increase in myopia and diabetic retinopathy.

Here are some facts about blindness and MSVI:

• 36 million people worldwide are blind
• 217 million are categorized as MSVI
• 253 million are visually impaired
• 1.1 million people have near vision impairment that could be fixed with eyeglasses
• 55% of visually impaired people are women
• 89% of visually impaired people live in low or middle-income countries
• 75% of vision impairment is avoidable
• 81% of people who are blind or have MSVI are aged 50 years or over
• Almost half of all students in Africa’s schools for the blind would be able to see if they had a pair of glasses.

What can we do?

To help combat global blindness and vision impairment, we first have to be educated. Learn about proper eye health and eye care and educate your children, family and friends. Implement that knowledge into your life with preventative eye care and regular eye doctor visits. Fighting blindness starts at home.

Next, consider donating your old eyewear. Eyewear donations can be extremely valuable to underdeveloped countries. Most eye doctors accept donations of old eyewear and give them to organizations like the Lions Club or VOSH that do humanitarian missions to other countries and provide eyecare and eyewear. Old glasses that we take for granted here or that are gathering dust in a drawer somewhere can be life changing for someone in a poor or underdeveloped country.

In addition, there are a number of organizations that assist the world population in preventing blindness and providing education and eye care to underprivileged societies. You can help fight blindness and MSVI by supporting these causes and the many others out there doing humanitarian work in this field. Here are a few examples:

• Eye Care 4 Kids: eyecare4kids.org
• Sightsavers: www.sightsavers.org
• See International: www.seeintl.org

Through support, research, education and outreach, we hope to stop the rapid pace of increasing unnecessary blindness around the world. So spread the word. When we all come together, we can accomplish our goals!

Hey women! Did you know that women are more likely to suffer from vision problems and are at higher risk of permanent vision loss than men? Well 91% of the women surveyed recently didn’t know that, which means that many of them aren’t taking the necessary precautions to prevent eye damage and vision loss.  

According to a recent study, the statistics for many of the major vision problems show that women have a higher percentage of incidence than men. These include:

• Age-related Macular Degeneration 65%
• Cataracts 61%
• Glaucoma 61%
• Refractive Error 56%
• Vision Impairment 63%

Women are also more susceptible to develop chronic dry eye, partially because it is often associated with other health issues that are more common in women such as ocular rosacea which is three times more prevalent in women.  Hormonal changes during pregnancy and menopause can also contribute to dry eye.  

It’s important for women to know the risks for eye-related diseases and vision impairment and the steps they can take to prevent eventual vision loss.  Here are some ways that you can help to protect your eyes and save your eyesight:

• Find out about family history of eye diseases and conditions.
• Protect your eyes from the sun by wearing 100% UV blocking sunglasses when outdoors.
• Don’t smoke.
• Consume a healthy diet with proper nutrition and special eye health supplements as prescribed by an eye doctor.
• Adhere to contact lens hygiene and safety.  
• Adhere to cosmetic hygiene and safety precautions. 
• Protect your eyes against extended exposure to blue light from computers, smartphones and LED lamps. 
• If you are pregnant or planning to become pregnant and have diabetes, see an eye doctor for a comprehensive eye exam. In women who have diabetes, diabetic retinopathy can accelerate quickly during pregnancy and can present a risk for the baby as well. 

Mothers are often charged with caring for the eye health of the entire family, but too often their own eye health needs fall to the wayside. It is critical that mothers take care of their eyes and overall health so that they can be in the best condition to care for their families. 

Speak to your eye care professional about your personal eye health and vision risks and the precautions and measures you should take to protect your eyes.  Encourage the other women in your life to do so as well.  Once vision is lost, it often can’t be regained and there are many steps you can take to prevent it with proper knowledge and awareness.  

The most important way to prevent vision loss is to ensure you schedule regular eye exams. Don’t wait for symptoms to appear as many eye issues are painless and symptomless, and sometimes by the time you notice symptoms, vision loss is untreatable. 

Eye color is a hereditary trait that depends on the genes of both parents, as well as a little bit of mystery. The color of the eye is based on the pigments in the iris, which is a colored ring of muscle located at the center of the eye (around the pupil) that helps to control the amount of light that comes into your eye. Eye color falls on a spectrum of color that can range from dark brown, to gray, to green, to blue, with a whole lot of variation in between. 

Genetics

The genetics of eye color are anything but straightforward. In fact children are often born with a different eye color than either of their parents. For some time the belief was that two blue-eyed parents could not have a brown-eyed child, however, while it’s not common, this combination can and does occur. Genetic research in regards to eye color is an ongoing pursuit and while they have identified certain genes that play a role, researchers still do not know exactly how many genes are involved and to what extent each gene affects the final eye color.

The Iris

Looking at it simply, the color of the eye is based on the amount of the pigment melanin located in the iris. Large amounts of melanin result in brown eyes, while blue eyes result from smaller amounts of the pigment. This is why babies that are born with blue eyes (who often have smaller amounts of melanin until they are about a year old) often experience a darkening of their eye color as they grow and develop more melanin in the iris. In adults across the globe, the most common eye color worldwide is brown, while lighter colors such as blue, green and hazel are found predominantly in the Caucasian population. 

Abnormal Eye Color

Sometimes the color of a person’s eyes are not normal. Here are some interesting causes of this phenomenon.

Heterochromia, for example, is a condition in which the two eyes are different colors, or part of one eye is a different color. This can be caused by genetic inconsistencies, issues that occur during the development of the eye, or acquired later in life due to an injury or disease. 

Ocular albinism is a condition in which the eye is a very light color due to low levels of pigmentation in the iris, which is the result of a genetic mutation. It is usually accompanied by serious vision problems. Oculocutaneous albinism is a similar mutation in the body’s ability to produce and store melanin that affects skin and hair color in addition to the eyes.

Eye color can also be affected by certain medications. For example, a certain glaucoma eye drop is known to darken light irises to brown, as well as lengthen and darken eyelashes.

Eye Color – It’s More Than Meets the Eye

It is known that light eyes are more sensitive to light, which is why it might be hard for someone with blue or green eyes to go out into the sun without sunglasses. Light eyes have also shown to be a risk factor for certain conditions including age-related macular degeneration (AMD).  

Color Contact Lenses

While we can’t pick our eye color, we can always play around with different looks using colored contact lenses. Just be sure that you get a proper prescription for any contact lenses, including cosmetic colored lenses, from an eye doctor! Wearing contact lenses that were obtained without a prescription could be dangerous to your eyes and your vision.
