The risk of sun related eye problems is higher for people who:

• spend long hours in the sun
• have had cataract surgery* or have certain retina disorders
• are on certain medicines, such as tetracycline, sulfa drugs, birth control pills, diuretics andtranquilizers that increase the eye's sensitivity to light.

*If you have had cataract surgery, you may be more at risk of injury from sunlight unless the artificial lens you received during surgery absorbs UV rays.
