Most age-related cataracts start small, and you may not notice any changes in your vision right away. As the cataract grows larger, many people begin to notice blurry vision or other symptoms that may develop gradually over time.
The lens of the eye is located just behind the iris (the colored part of the eye) and the pupil. It is transparent so that light can pass through it easily. When working properly, light focuses on the back of the eye (the retina) to form clear, sharp images of what you see, and nerves transmit those images to the brain.
As we age, proteins in the lens start to break down and the lens gradually becomes cloudy. As a cataract develops, the lens delivers fuzzy images to the retina, causing blurred vision. There are three main types of cataracts – nuclear, cortical, and posterior subcapsular – and each type can affect your eyesight differently.
- Nuclear cataracts: These cataracts affect the center of the lens and are the most common age-related cataract. In the early stages, a nuclear cataract can increase nearsightedness. As it progresses, the lens gradually yellows and begins to cloud your vision. Many people find that colors become less vivid, and night driving can be particularly difficult.
- Cortical cataracts: A cortical cataract clouds the edges of the lens, called the cortex. These cataracts look somewhat like wheel spokes that point inward toward the center of the lens, causing light to scatter. Many people with this type of cataract experience problems with glare.
- Subcapsular cataracts: You may notice his type of cataract sooner because it develops at the back of the lens, directly in the path of light that is passing through on its way to the retina. It is most common in people who have had prolonged steroid use or suffer from diabetes. Common symptoms include blurry reading vision, halos and glares at night, and sensitivity to light.
Watch for These Signs
Cataracts are most often associated with the aging process, but can also affect younger people. Eye injuries, certain medications, and genetic conditions can cause cataracts, even in babies. These cataract symptoms and vision changes could also be signs of a different eye condition:
- Cloudy, blurry or distorted vision
- Light sensitivity
- Glare and halos around bright lights
- Increasingly poor night vision
- Frequent changes in eyeglass or contact lens prescription
- Fading or yellowing of colors that were once vivid
- Double vision in one eye
You may also notice that you blink more than usual to try to clear your blurry vision, or that you need more light to complete tasks that you were once able to do with normal light levels.
If you suspect you may have cataracts, be very careful at night and don’t drive when your vision is compromised.
