Cataracts occur when the eye’s lens becomes clouded. This is caused by proteins in the lens becoming clumped. This clump of proteins can grow over time, causing gradual, decreased vision. Read below for more on this condition:
Cataracts symptoms range from blurred vision to a sudden (and temporary) improvement in near vision. For an individual with advanced cataracts, objects appear as if they are being looked at through a fogged-up window.

Treatment for cataracts starts with eyeglasses and stronger lighting, but as the disease progresses cataract surgery that involves cataract removal may be necessary. Luckily, this surgery is effective and safe. The procedure is simply removal of the clouded lens, which is replaced with a plactic intraocular lens.
