What is a Cataract?
A cataract is a clouding of the eye’s natural crystalline lens. The lens is responsible for focusing light and producing clear, sharp images. When we’re young the lens is clear but as we age, it begins to harden and become cloudy. The cloudy lens diminishes quality of vision.
Cataracts tend to develop slowly starting in your 40’s and 50’s. You may not notice any changes with your vision at first. As the cataracts worsen, you may find they interfere with your day to day activities.
Common symptoms of cataracts are:
- Clouded, blurred or dim vision
- Increasing difficulty with vision at night
- Sensitivity to light and glare
- Need for brighter light for reading and other activities
- Seeing "halos" around lights
- Fading or yellowing of colors
- Double vision in a single eye
At first, the cloudiness in your vision caused by a cataract may affect only a small part of the eye's lens and you may be unaware of any vision loss. As the cataract grows larger, it clouds more of your lens and distorts the light passing through the lens. This may lead to more noticeable symptoms.
Cataracts generally develop in both eyes, but not evenly. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.
