A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. The lens is a clear oval structure with three layers: the nucleus, the cortex and the capsule. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. You have a cataract when the nucleus becomes opaque (no longer clear) or when small opacities develop in the cortex that block or scatter light.
Cataract Signs and Symptoms
A cataract starts out small and at first has little effect on your vision. In fact, in the early stages, only a doctor can detect a cataract because there may not be any symptoms. When you do start to notice changes in vision, they could include:
- Blurry distance vision, especially outdoors;
- Streaks or rays of light seeming to come from headlights and stop lights;
- Instinctively shading your eyes from the sun, or feeling more comfortable wearing a visor;
- Print appearing faded and lacking in contrast;
- Colors appearing faded in hue (Blue may appear to be green and yellow may look white).
