A cataract is a clouding of the lens of the eye, which is normally clear. They grow slowly, but as the clouding worsens vision can be affected.
Common symptoms of cataracts include:
Not all cataracts need treatment. In many cases, an ophthalmologist may monitor your vision for years before treatment is needed.
