Possible risk factors for cataracts include:
Probably the greatest risk factor for cataracts is age. And, although age-related cataracts may develop between 40 and 50 years old, vision is usually not affected greatly until after age 60.
• geographic location
Recent studies have shown that people who live in high altitudes are more at risk for developing a cataract(s).
• excessive sun exposure
Person who spend more time in the sun may develop cataracts earlier than others. The American Academy of Ophthalmology now recommends wearing sunglasses and a wide brimmed hat to lessen exposure to ultraviolet rays.
