Cataracts are blurs in the lens of the eye that are found in the front of the eye behind the cornea. They can be acute or chronic. 

• Cataracts are the most common cause of blindness, having affected 18 million population, or 48% of all blindness in the world.

• Age factor: Among people of 75-year-olds, about half have blur in the lens, which affects vision. Nearly all in their 80s have various degrees of opacity in the lens.


They develop gradually and almost imperceptibly, but can worsen quickly within a few weeks.

Patients do not necessarily feel pain, burning or itching in the eyes, or any discomfort if the changes are modest. The genes usually start on one eye, but over time, both eyes will be affected. For example,

- reduced vision, both at a distance and close by

- double vision, which does not disappear when you cover one eye

- problems with glare, especially if suddenly exposed to bright light...


Cataracts cannot be prevented. However, the risk of getting cataracts is reduced if you can prevent or treat diseases such as diabetes, injuries or other eye diseases.
