These five symptoms can be early signs of cataracts:
1. Cloudy vision. A cataract occurs when the lens of the eye becomes cloudy. At first a cataract is small, so only a tiny part of your lens is affected, and you may not notice it. Over time, however, the cataract will grow and cause cloudy vision.
2. Lens discoloration. When you have cataracts, your lens slowly changes to a yellowish or brownish color. This adds a brownish tint to your vision. As with cloudy vision, the change in tint may at first be so slight you may not notice a vision problem. However, with time, the tinting or fading of colors can increase, making it more difficult to perform everyday tasks, such as reading or watching television. As the lens discoloration advances, you may not be able to identify colors, especially blue and purple.
3. Myopic shift. This happens when a person used to be able to see really well far away but needed reading glasses. All of a sudden they don’t need reading glasses anymore, but their distance vision has gotten much worse. This is a sign that the cataract is starting to evolve. It’s caused a change in the lens, and the patient has become very nearsighted. The change is only temporary. In a very short period of time, however, the lens will become very cloudy, and his or her vision may further deteriorate.
4. Poor night vision. People who used to be able to drive well at night and who did not get a lot of glare or star-bursting from oncoming cars find it much more difficult to drive at night.
5. Glare and halos. If you are developing cataracts, you may find that light from the sun, an oncoming car’s headlights, or lamps seem too bright. Cataracts can cause you to see glare or halos around the light sources.
