What is cataract?

It is a type of eye disease with various reasons, beginning with blurriness of the lens of the eye and as the lens becomes more blurry, the vision of the eye is disturbed. Fortunately, in most cases where cataract causes visual impairment, it can be treated with a delicate surgery.

Common causes of cataracts

  • Old age (the most common cause);
  • An impact that disrupts the nutrition of the lens;
  • Ionizing rays, x-rays, gamma rays caused by old televisions;
  • Prolonged exposure to sunlight or ultraviolet rays;
  • Diabetes;
  • Injury to the eye and lens;
  • Congenital impairment;
  • Malnutrition;
  • Long-term use of some drugs such as corticosteroids.

Some common symptoms of cataract

  • Diplopia;
  • Blurred vision, usually happening in bright light. Usually, this state happens for the first time at night when seeing the lights of cars in the form of a halo;
  • Pupils becoming blurry and milky white;

According to the researchers, using non-standard sunglasses damages the eyes more than not wearing them, being a reason for the occurrence of cataracts. Accordingly, dark sunglasses cause the pupils to open and if the glasses are not able to absorb UV rays, this rays will cause damage to the eyes more than when a person does not wear glasses.
