Cataracts are caused by a clouding of the eye's natural lens, which causes fuzzy sight and other visual symptoms. Because the onset is often quite slow, people don't always know they have cataracts developing until the symptoms become severe or the problem is noticed by an optometrist. Once someone has developed cataracts, they'll need cataract surgery to replace the cloudy lens with an artificial one, which is usually a quick and easy procedure despite how complex it might sound.

Ocular sarcoidosis is an inflammatory condition that occurs when your body's immune system overreacts to a threatening substance, such as bacteria or a virus, and causes clumps of inflammatory cells to form in the eye. Ocular sarcoidosis typically affects the conjunctiva, uvea or optic nerve. It's not fully understood why some people are more susceptible to developing this condition than others, but women and those with a family history of sarcoidosis are at an increased risk.
