But there are many other common symptoms as well. The first symptom of a cataract may be progression to becoming more nearsighted. Other early symptoms may be poor night vision or glare. Cataracts can also affect a person's ability to detect contrast and can affect your color perception. The second image is what you may see through a cataract when it blurs the vision and alters the contrast sensitivity.
Cataracts tend to progress very slowly.
The rate of progression varies on the individual and on the individual eye. It also depends on the presence of other illnesses and on the use of certain medications. Of course, this will vary widely based on the individual person. A cataract has to be removed via surgery, NOT laser. In Europe, scientists are experimenting with a laser that is strong enough to break up a cataract.
