This common condition occurs when the internal clear lens inside our eye becomes less transparent and affects our vision.

It happens more often in people over 60, but it can also be found in younger patients, or even newborns (congenital cataracts).


Cataracts can be caused by advancing age, due to internal changes within the lens. It can be also inherited, or as a result of injury, disease, or certain medications. Risk factors include UV exposure, cigarette smoke. There is no way to prevent cataracts, but wearing UV protection can decrease the risk associated to that radiation exposure.

Symptoms and Signs

Cataracts are painless. The only indication someone may feel is blurry or hazy vision. Sometimes that comes along with a prescription change, and updating the glasses prescription can improve the blurriness. Other times there can be glare, especially at night.


When the vision is not good enough, and the mentioned change in vision cannot be improved by a new prescription glasses, the optometrist can refer you to an eye surgeon in order to do a cataract surgery assessment.
