When the eye lens thickens and becomes cloudy or opaque, then the eye cannot focus or handle light properly. This eye condition is called a cataract. The primary symptom of a developing cataract problem is a slow and painless loss of vision.
Cataracts are the number one cause of blindness in the world.
Sometimes, a cataract can swell causing secondary glaucoma. Senile cataracts are the most common, affecting persons over 65 years of age. These cataracts are often caused by free radical damage. These free radicals attack the structural proteins, enzymes, and cell membranes of the lens of the eye. These free radicals maybe in our food, water, air, and environment are probably the primary cause of increasing number of people suffering from cataracts.
