Cataracts: causes, symptoms and treatment
The appearance of cataracts is related to age and affects more than 50% of those over 65 years of age.
How are cataracts produced? Inside the eyes, we have a natural or crystalline lens. It refracts light rays entering the eye to help us see. The crystalline lens should be transparent and, if a cataract occurs, it becomes cloudy.
The most common cause is aging, but not the only one. Having relatives with cataracts, suffering from diabetes or having suffered an eye injury are other reasons that cause it.
To detect the presence of caratata early, you must take into account a series of symptoms: blurred vision, sensitivity to light, difficulty seeing at night...
One of the preventive actions is to use sunglasses that filter the ultraviolet light rays (UV) of the sun. Periodic review with the ophthalmologist or optometrist optician is also recommended, especially from the age of 40-45.
