What is a cataract?

Many people have heard the term cataract before, but are unsure as to what exactly it is. A cataract is a clouding of the natural crystalline lens of the eye. This lens sits right behind the iris, the colored part of the eye. It is used to help focus when reading at near. Due to ageing, ultra-violet light exposure, injury, or certain medications, it can start to yellow and become opaque. This clouded lens, or cataract, can cause a glasses prescription change, glare, blur, and washing out of colors. Once the visual symptoms become bothersome enough, your optometrist will refer you to an eye surgeon to have it removed. An artificial lens is then inserted into the eye to help maintain the optical power of the eye.
One of the best ways to slow down the progression of cataracts or delay their onset is to protect your eyes from UV light. This can be achieved by wearing sunglasses when outdoors. This is important year round, not just in the summer months. Your optometrist will monitor for any cataract changes at your yearly eye exam.
