We received an email to write about cataracts, so breaking the chain of Vitamins, We will continue with Vitamins after this blog.
Let’s start with the description of eye, the cornea is the transparent external membrane of the eye. It is the one to receive the first impact of light. Next to the cornea comes the Iris, a thin colored ring(that gives color to the eyes). This Iris includes the Pupil, which controls the amount of light that enters the eye through dilation and contraction. Behind the Iris is the Crystalline lens or optical disc. This is where the light rays are finely focused to form the image on Retina, situated in the rear of the eye. All together they form the Eye ball.
Now, you know the structure of eye, let’s come back to the topic, Cataracts are the condition in which the lens of the eye (Crystalline lens) becomes cloudy or opaque. It becomes difficult to focus on objects and things seem dark to the person. The whitish or opaque appearance indicates a change in the lens fibers. It is similar to the change of an egg white when it is cooked.
Symptoms: Progressive loss of vision, no pain but some sensitivity to light, sometimes you can see radiance around points of light.
Most common causes:
Diabetes and the combination of drinking large quantities of milk and not being able to process galactose, which is a sugar abundant in milk.
Deposits of calcium and cholesterol in the capillaries of the eyes which reduce blood circulation to the eyes.
It can also be caused by a blow or injury to the eye, and by inadequate nutrition.
Too much sun tanning can cause cataracts since sun’s ultraviolet rays cloud the crystalline lens causing opacity of the lens. The effect light produces on the lens is similar to that of heating of an egg white, it becomes opaque. Cataracts also seem to be part of normal aging process and exposure to X-rays can also cause it.
SUGGESTIONS : Take food containing Beta- carotene, Vitamin C and Vitamin B-2, The principal antioxidants in the lens of the eye are Vitamin C & E. Both are needed to activate Glutathione. Glutathione is a protein fragment which protects the eyes from damage produced by free radicals.
