Understanding Cataracts: What They Are and How They Affect Vision
Knowing about cataracts is key to keeping your eyes healthy and preventing vision loss. We’ll cover the basics of cataracts, including what they are, where they are in the eye, and their symptoms.
What Is a Cataract Eye Condition?
A cataract is a cloudy area in the eye lens, which is behind the pupil. This cloudiness blocks light from reaching the retina, causing vision to blur. As we get older, the lens loses flexibility and may develop cataracts, impairing vision.
Where Is Cataract Located in the Eye
The cataract is in the lens of the eye, a clear, flexible part behind the iris and pupil. The lens is vital for focusing light on the retina. When it becomes cloudy from a cataract, it messes up how the eye focuses light, causing vision issues.
Common Symptoms of Cataracts in Humans
Common symptoms of cataracts include:
- Blurry or cloudy vision
- Double vision or ghosting
- Sensitivity to light and glare
- Fading or yellowing of colors
- Difficulty reading or driving at night
These symptoms happen because the cataract blocks light from reaching the retina, affecting how well you can see.
Spotting cataracts early is important for treatment. Regular eye checks can catch cataracts early, allowing for timely treatment.
