Can cataract be prevented or treated with medication?

Cataracts that occur due to the ageing process cannot be prevented as the ageing process itself cannot be prevented. Using the eyes for reading and similar activities has nothing to do with cataract formation. Avoiding the use of eyes will not prevent cataract.

Till date as per all authentic medical research no medication exists to prevent or cure a cataract. The only known treatment for cataract is surgery.
