Denver is a great place to live because of our fantastic scenery and clear skies. Many of our city’s great qualities are owed to the fact that we sit a mile above sea level. However, because we have less atmosphere to filter out the sun’s radiation, we receive more ultraviolet (UV) light than those living at sea level. Your eyes are very sensitive to UV light, and the consequences of UV light on the eyes and vision can be severe. Cataracts are common opacifications of the crystalline lens that sit behind the iris. UV light contributes to the formation of cataracts. Macular degeneration is a disease that results in central blindness and is also due to UV light being absorbed by the most sensitive part of the retina, the macula. There are many ways you can reduce the amount of UV light your eyes absorb. Sunglasses can block UV light, as can clear lenses made of polycarbonate or trivex. Some contact lenses block UV light including Acuvue’s 14-day replacement Oasys lens (also available for astigmatism). At your comprehensive exam, Dr. Abert and Dr. Pedroza will discuss how you can protect your eyes to ensure a lifetime of healthy eyes and vision.
