What is a Cataract?

A cataract is a clouding of the lens of the eye. The lens is responsible for focusing light onto the back of the eye, which is then translated into images for the brain to process. When a cataract forms, the lens becomes clouded, making it more difficult for light to pass through. This can lead to vision problems such as blurred vision, double vision, or light sensitivity. Cataracts can also cause colors to appear faded or yellow.

The most common type of cataract is called a nuclear cataract, which develops in the center of the lens and typically progresses slowly. Another type of cataract is called a cortical cataract, which develops in the outer edges of the lens and tends to move more quickly. In rare cases, a cataract may be caused by trauma or an underlying medical condition.

While the exact cause of cataracts is unknown, some factors have been linked to their development. Age is the most common risk factor, as the risk of developing cataracts increases. Other risk factors include smoking, excessive exposure to sunlight, certain medications, and certain medical conditions such as diabetes. 

The most common symptom of cataracts is blurred vision. Other symptoms may include double vision, difficulty seeing at night, and light sensitivity. Colors may also appear faded or yellowed, and light glare may be more pronounced. If you have any of these symptoms, you can consult one of our eye care specialists here at House of Optical.
