Behind the iris is a lens, which helps your eye focus light. In the majority of the population, this lens is transparent. However, aging, certain diseases, trauma to the eye, medications, and environmental factors such as air pollution and UV light can cause this lens to discolour or develop opacities. These changes are called cataracts and they affect the ability of the eye to focus light, much like a fingerprint on glasses or dirt on a window. If the cataract matures, many people notice blurry vision that is not correctable with glasses. Other symptoms of cataracts are glare, halos, and changes to colour vision. Once the vision loss is affecting daily activities, cataract surgery may be considered.
