Caused by several factors—injury, severe inflammatory disease of the eye, drug reactions or radiation, disease such as glaucoma or diabetes, sun exposure, smoking or congenital. Most develop late in life due to aging.

At a cellular level cataract is basically clouding in the lens which obstructs the passage of light.

Not really sure what you are after ... hope that helps.

Cataracts typically result from aging, or are due to UV radiation - but all cataracts, no matter the cause, involve the clumping of oxidised crytalline proteins within the lens.

i got this from this guy called kuya
The most common cause of cataracts is the ageing process although they can develop cataracts at any age even infancy. As we age, the lenses in our eyes become less flexible, less transparent and thicker. The lens is made mostly of water and eye proteins. As the eyes get older, certain eye proteins such as alpha-crystalline fail to function properly. Alpha-crystalline is important in protecting other lens proteins. If they fail to work, normal clear lens proteins would clump together and lose their transparency clouding some part of the lens (cataract develops). Alpha-crystalline can also be damaged by highly charged, unstable molecules known as free radicals that may have resulted from smoking and exposure to UV light.
