Cataracts are a 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 in color 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.

The most common causes are:

      • 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.
  • They can also be caused by a blow or injury to the eye, and by inadequate nutrition.
  • Too much sun tanning can cause cataracts since the 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 the normal aging process. Also, exposure to X-rays can cause them.
