Cataracts (lens opacities) are common in all populations and most are related to the physiology of aging. However, many others are the result of gene changes (mutations). Many of these are present at birth and often associated with other health problems.

Vitamin C (Ascorbic Acid)
Several experimental and epidemiologic studies have shown that long-term consumption of vitamin C supplements may substantially reduce the development of age-related lens opacities. [Am J Clin Nutr, 1997 Oct, 66:4, pp.911-6]

A cortical cataract may give rise to poor vision associated with seeing haloes around lights or seeing things double with one eye.
Posterior subcapsular lens opacities tend to cause reduction in vision (especially for reading), susceptibility to bright lights and glare.

Closure of the iridotomy site is more likely if a uveitis presented after surgery. Up to 45% of patients will have anterior lens opacities after laser iridotomy, but these opacifications do not put the patient at an increased risk of cataracts.
