subject: Cataract operations – A routine surgery [print this page] If you are concerned that you may have cataracts then you should consult a medical professional, but there are a number of symptoms that you can look out for. The most common symptom is blurred vision, where everything you see appears hazy. You may also find that you are dazzled by bright lights, so may find it difficult to be out in the sunlight. Your ability to distinguish colours may also be affected. There are other conditions which can cause similar symptoms, such as dry and wet macular degeneration, and your optician will be able to rule out other possible causes.
