What are Cataracts?
A cataract is a clouding of the lens in the eye that leads to a decrease in vision. It is caused by protein clumping that occurs over time and results in the lens becoming opaque. This prevents light from properly passing through the lens to the retina at the back of the eye, causing blurred vision.
Cataracts tend to develop slowly over many years and are very common in older adults, with most people over the age of 60 having some degree of cataract formation. The cloudy areas in the lens prevent clear images from forming on the retina, making vision hazy and colors appear faded.
