Cataracts: A Cause of Cloudy Vision

By Dr. Ashley Verdon

What is a Cataract?

A cataract is a clouding of the lens inside the eye, which leads to a progressive blurring or dimming of vision. The lens sits just behind the pupil and is responsible for focusing light. As the lens increases in cloudiness, it becomes more difficult to see objects clearly and bright lights can cause glare. The most common form of cataract is due to the natural aging process of the eye. Other common causes include trauma, steroid use and diabetes.

A cataract starts out small and initially has little to no effect on vision.  As the cataract progresses, it becomes harder to read and night driving can be difficult as patients often experience visually debilitating glare. In the early stages, your doctor may recommend changing the eyeglasses prescription to provide temporary visual improvement. In addition, anti-glare coatings on eyeglass lenses can help reduce glare for night driving.

How Do You Avoid Cataracts?

You may be able to slow down your development of cataracts. Protecting your eyes from sunlight is the best way to do this. Wear sunglasses that screen out the sun’s ultraviolet (UV) light rays.  Annual comprehensive dilated eye exams allow optometrists to diagnose the early signs of cataracts. Depending on the stage of cataract formation patients may be advised to monitor for increased visual symptoms and follow a regular check-up schedule.

When cataracts disrupt your daily life, your doctor may recommend cataract-removal surgery. Our relationship with local ophthalmologists keeps you seeing your best. If you are concerned about cataracts don’t wait, contact us today at 585-349-3300!
