Do Cataracts Affect my Vision?

Cataracts cloud the lens that lies behind the iris and the pupil. As a cataract grows it clouds more of the lens and makes it progressively harder to see.

How do Cataracts Affect my Vision?

There are two ways that cataracts can affect vision:

  • The lens is made of mostly water and protein. Cataracts occur when that protein clumps together, clouds the lens and reduces the light that reaches the retina. The clumps of protein diminish the sharpness of the image that reaches the retina. When the cataract is still small, only a small part of the lens is affected and you may not notice any vision changes. Cataracts usually grow slowly so vision slowly gets worse. As the cataract increases in size, cloudiness in the lens will increase and vision will become more limited.

Cataracts and Your Vision

  • The lens of your eye should be clear. With cataracts, the lens slowly changes to a muddy color and could add a brownish look to your vision. That tinting can make it more difficult to read or perform other activities.

What are Ways to protect my Vision from Cataracts?

Wear sunglasses and a hat to help block ultraviolet sunrays to help delay cataracts. Don’t smoke. Follow good nutrition habits such as eating green leafy vegetables, fruit and food with antioxidants.

If you are 50 years and older, see your ophthalmologist every year for a comprehensive dilated eye exam. If you have any problem with your eyes, contact your ophthalmologist immediately. Early diagnosis and treatment can save your sight.
