What causes cataracts?
Although scientists do not know for sure what causes cataracts, they suspect there could be several possible causes including:
- excessive exposure to sunlight
- steroid use
- diuretic use
- certain major tranquilizers
For several of the potential causes listed (i.e., steroids, diuretics, and/or major tranquilizers), additional research is needed to differentiate the effect of the disease from the effect of the drugs themselves.
