Cataracts: Question of the Day: What causes Cataracts?

A Cataract is a clouding or opacification of the Crystalline Lens within your eye. As the name implies the Crystalline Lens is crystal clear in its normal state.The Crystalline Lens is composed of clear protein much like the white of an egg. As protein denatures and decomposes it changes its structure and in doing so changes its optical clarity. This is the formation of a Cataract. The Crystalline Lens proteins can change due to exposure to radiation-sunlight is UV radiation, so protect your eyes from the sun as excessive sun exposure may accelerate the formation of a Cataract. Certain medications such as cortisone and steroids used to treat asthma can cause Cataracts to form as can having Diabetes. Or as is the most common cause of Cataracts-they can form due to absolutely no reason, just simply age. Age Related Cataracts are the most common types of Cataracts.
