Food for Sight

It’s a well-known fact that carrots are good for your eyesight, but did you know there are several nutrients that can keep your eyes healthy throughout your life? A healthy diet may help reduce the risk of vision issues like cataracts, glaucoma, age related macular degeneration and diabetic retinaopathy and help promote good eye health from as early as infancy.

Beware of Cataracts

Cataracts are the most common cause of vision loss in people over age 40 and blindness worldwide. A cataract is a clouding of the eye’s natural lens, which lies in the middle part of the eye that helps to focus light onto the retina (light-sensitive tissue at the back of the eye). The most common symptoms of a cataract are blurry vision, sensitivity to light and glare, and increasing difficulty with night vision. Symptoms of early cataract may be improved with new glasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. If these measures do not help, surgery is an option that involves removing the cloudy lens and replacing it with an intraocular lens (IOL) implant, thus allowing light to properly enter the eye again.

Risk factors for cataracts include age, diabetes, excessive exposure to ultraviolet radiation, prolonged use of corticosteroid medications, and smoking. Cataracts can affect the center of the lens (nuclear cataracts), the edges of the lens (cortical cataracts), and the back of the lens (posterior subcapsular cataracts). Although most cataracts are related to aging, other types of cataracts include secondary cataracts (from health problems like diabetes or due to steroid use), traumatic cataracts (after an eye injury), and congenital cataracts (present at birth).

Have your eyes examined yearly. Your optometrist will perform a dilated eye exam including a visual acuity test and refraction to assess your risk for a cataract and discuss appropriate treatment options.

UV Rays Can Seriously Damage Your Eyes, Even In the Winter

Everyone knows that UV radiation causes skin damage.  But those same rays can cause cataracts, cancer of the eyelids, benign growths on the eye’s surface, and snow blindness.

Beach dwellers and skiers are at particular risk.  UV radiation reflects off surfaces such as snow, water, and white sand.  The risk of ocular damage from UV radiation is particularly high on the beach, the waves, and at the ski slopes.

People need to wear sunglasses outdoors when working, driving, playing sports, or running errands.  At a minimum, lenses should:

  • Block at least 99% of both UV-A and UV-B radiation.
  • Screen out 75% to 90% of visible light.
  • Be gray for proper color recognition and free of distortion and imperfection.

Buying Sunglasses — What to Look for:

  • Check lenses to be sure the tint is uniform
  • Ensure that lenses are distortion free.
  • Try them on in front of a mirror. If you can see your eyes easily through the lenses, they probably don’t block enough light. Note: this test doesn’t apply to photo chromic (light-sensitive) lenses.
