Take Time and Discuss Your Eyes and Vision With Your Eye Doctor – Cataracts Are Not an Eye Emergency
Sun ,13/09/2009
A cataract is a clouding, opacity, yellowing, or accumulation of fluid in the lens of the eye that results in a loss of vision and interferes with your lifestyle. Most cataracts are related to aging, and by the time you reach the age of 70 most people will show some signs of cataracts. Age related cataract may occur in one eye first but with time will usually be present in both. The lens is a clear part of the eye that helps to focus light, or an image, on the tissue lining the back of the eye called the retina. The retina is lined with the receptor cells that transform light particles into electrical impulses. A healthy lens is transparent due to the special proteins that help the layers repeat in a regular pattern that causes the least interference and passes the most light through.
The lens does some filtering of the ultraviolet radiation from the sun preventing UV from reaching high levels in the retina. While the lens filters out UV in both the A and B bands, it filters virtually all of the UV radiation between 320 to 400 nan meters and the proteins responsible oxidize over time. Free radicals also increase and the lens yellows and loses transparency as water starts accumulating in-between the layers.
Eye surgery for glaucoma and other conditions can lead to cataract formation. Certain health conditions like diabetes can also cause cataracts, occasionally very rapidly and in some instances also rapidly reversible. Unfortunately, they are usually permanent. Prescription steroid medications used long term can result in cataract development. Traumatic cataracts result after serious eye injuries but usually will not progress over time like age related cataracts. Infants occasionally are born with cataracts or develop them in early childhood, These cataracts may be so small and enough off the line of sight that they do not affect vision. While technically a cataract, I feel an opacity needs to cause lifestyle interruptions before they should be labeled as a cataract. Cataracts are best described by function rather than form. If they do interfere with your daily life, the lenses may need to be removed. Radiation exposure can result in cataracts if the dose is high enough or accumulates over repeated exposure.
First and foremost, keep in mind that vision insurance benefits are a supplement to health insurance. If you do not have an occupation or affiliation that will allow you to acquire insurance, you may want to consider purchasing insurance on your own to take care of your medical needs. Yet the selection aspect can be puzzling to some since there are different kinds of vision insurance available.
Smoking is the best thing you can do if you want to develop cataracts at a young age. Smoking also is associated with the other leading causes of blindness, glaucoma and central retinal degeneration. Reducing your UV sun exposure by wearing quality sun glasses that meet A.N.S.I. standards is helpful. Sun wear that wraps and blocks sun exposure from the side is even more helpful. Although research studies have given mixed results, time will probably bear out a protective effect of antioxidants on the lens tissue. Supplementation with vitamin C, vitamin E, and special plant pigments likely will be shown to reduce cataract development. Eating foods that are complex carbohydrates such as whole grains and less refined foods with a lower tendency to cause sharp rises and falls in blood sugar are associated with a decreased risk of cataract formation. Leafy green leafy vegetables, fruit, and other foods with antioxidants are always the best source of supplements.
Palming like this is one of the best eye exercise to relax your eyes, and can help improve your vision, especially during times of high stress and strain. So the next time you find yourself stressed out, feeling strained, and having some vision problems, take a timeout to perform the palming eye exercise. It will help you relax your eyes.
