Cataracts cause a clouding of the lens in the eye, making your vision appear to be foggy. Cataracts are the most common cause of vision loss in people over 40 and are the leading cause of blindness in the world.
Your eyes are meant to naturally adjust to normal light changes, adjust focus, and allow us to see both near and far. Your lens is primarily made up of water and proteins. The proper arrangement of these proteins is what contributes to normal vision. Some of these proteins clump together forming a clouding of the lens.
Cataracts are primarily related to aging, but other factors can contribute to their development, including:
Symptoms of cataracts can vary, but common signs include:
Early symptoms of cataracts can often be managed with new glasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. However, if these measures do not help and your vision loss interferes with your daily activities, you might need surgery. Cataract surgery is a common and generally safe procedure where the cloudy lens is removed and replaced with an artificial one.
