What is a Cataract?
Cataracts are a clouding of the lens in the eye. The lens, which lies behind the iris and pupil, is normally clear. The lens is responsible for focusing light onto the retina at the back of the eye; that light information is converted into electrical signals which are sent to the brain to be interpreted into an image—what we see. As the lens become cloudy the light getting to the retina is diminished and often scattered. This scattering of light causes blurriness in one’s vision. As the lens becomes cloudier this blurriness will increase and patients will often state that they feel like they are looking through a frosted piece of glass. Clouding of the lens will also cause colors to appear less vibrant and often with a yellow tint. The light scattering caused by cataracts often results in glare from car headlights at night, making night driving difficult and sometimes impossible.
Symptoms of a Cataract
Generally, cataracts are a natural part of the aging process; however, trauma, metabolic changes, radiation, and toxic chemicals found in certain medications can lead to or hasten the onset. Cataracts only get worse, if left untreated it eventually leads to total loss of vision. Blindness caused by cataracts is not permanent, sight can be restored with surgical removal of the cataract.
Patients with cataracts often experience the following symptoms:
- Blurred vision
- Glare, or sensitivity to light
- Double vision in one eye
- Frequent changes in his/her eyeglass prescription
- Difficulty in reading in low light
- Declining night vision
- Fading or yellowing of colors
