A cataract starts as a small clouding of the lens and at first has little effect on your vision. Cataracts gradually get worse over many months or years. You may notice that your vision is blurred, like looking through a frosted window. A cataract may also make light from the sun or a lamp seem too bright or glaring / dazzling. Colours may not appear as bright as they once did.

The optometrist will look for signs of cataracts when you come in for an eye examination. However, if you think you may be developing cataracts ask him to tell you if they have detected any clouding of the lens in one or both eyes. Also, ask whether you would benefit from cataract surgery. If you do, you will be referred to a specialist clinic where further examinations will be made before the surgery is approved.
