EyeSight Vision Care - Eye Damage
July 10, 2010
What we feed our bodies feeds our eyes.
Many of the vitamins and minerals in our bodies are found in much higher concentrations in our eyes, so a diet lacking in these vitamins and minerals can lead to vision problems as we grow older.
Take the time every day to give your eyes (and the rest of your body) the nutritive support they need.
Eat the foods and take the supplements that provide the antioxidant vitamins and minerals your eyes require.
You’ll Protect Your Eyesight, ensuring years of good eye health, and increasing the odds that you’ll avoid blindness or vision loss for the rest of your life.

Do You Have a Vision Story That You Can Share?
I need your help.
I have a page on this website that is for my readers to tell their Eyesight story. My hope was to have people tell their story so it might help someone else with the same problem or experience.
But lately there has not been any activity on this page. Could you please look at this page and contribute someone if you can.

Here Comes the Sun
"Here comes the sun," the Beatles sang, "and it's all right" - though perhaps they should have substituted, "and if you don't protect yourself, you can jolly well get a nasty sunburn and skin cancer and even long-term, irreversible eye damage."
OK, as you head outside this month to weed your garden, skipper your sailboat, picnic in the park, or just head to work and back, here's what you need to know to be all right in the summer sun.
Fun Sun Facts
Children often draw the sun as a bright yellow circle that dominates everything else in the picture. Although the sun as seen in outer space is more white than yellow, the kids have got it right: the sun is by far the largest object in the solar system, containing 99.8% of the system's mass.
The Sun Gets in Your Eyes
If these facts aren't enough to convince you to slather on the sunscreen and slap on some shades, consider the following.
The damage to your eyes from the sun's ultraviolet (UV) rays is cumulative and can cause pteryguim (tissue growth on the whites of the eyes that can diminish vision) and age-related macular degeneration (deterioration of a part of the retina).
In addition, UV rays are the biggest culprit in the formation of cataracts. The World Health Organization estimates there are 16 million people worldwide who are blind as the result of cataracts, and as many as 20% of the cases may be due to UV radiation exposure.
Protect Your Eyes from Sun Damage
The best way to protect yourself from the sun is to stay out of it! This is not possible for most of us, however, so here are a few tips.
* UV radiation penetrates cloud layers, so protect your eyes even if you can't see the sun. * UV rays are most intense at midday, so try to avoid the sun between 10 am and 2 pm. * As with businesses, location matters: the higher your altitude, and the closer you are to the equator, the stronger the UV rays. * Likewise, snow, sand, and water reflect light more strongly. Take extra precautions if you are at these places. * Choose a good pair of sunglasses (see sidebar). And wearing a broad-brimmed hat doesn't hurt either. * Light-colored eyes need more protection than dark ones. * Don't forget the little ones: children's eyes are more vulnerable to sun damage.
Protect Your eyes, Your Eyes will thank you.
Vision Tip of the Month: How to Choose a Pair of Sunglasses
1. Look for a label that tells you how much UV protection the sunglasses offer. Ideally, your shades should block 99% to 100% of UV radiation.
2. Close-fitting sunglasses help block light more effectively: look for wraparound shades or large lenses.
3. Dark colored sunglasses don't necessarily protect you better. It's a special coating on the lens that makes them safe, not their darkness.
4. Gray, green, and brown lenses usually give better protection than other colors.
5. More expensive shades may be more fashionable, but they don't provide more protection.
Vision Facts of the Month
* People generally read 25% slower from a computer screen compared to paper.
* The eye of a human can distinguish 500 shades of the gray.
* The eyeball of a human weighs approximately 28 grams.
