Cataract is the clouding of the lens inside the eye, which leads in a decrease in vision. All people after a certain age show signs of cataract.

  • The eye lens is situated behind the iris, it has the size of a lentil and it is naturally transparent.
  • Cataract cannot be prevented nor cured with pharmaceuticals.
  • It is a very common disease and is correlated with aging.
  • In some occasions it can it be caused by eye injuries, certain diseases (e.g. diabetes, eye inflammations etc.) or certain treatments such as the long usage of cortisone.
  • In rare cases children can be born with cataract (relative cataract).


The main symptoms are:

  • Blurriness with progressive reduction of far or near sight.
  • Vision becomes gradually less accurate.
  • Seeing reflections and shines around objects.
  • Attenuated color perception.
  • Intense sun irritation.
  • Absence of pain.

All the above symptoms can influence daily activities such as:

  • Driving, especially in the evening or under strong lighting.
  • Reading books/newspapers or watching television. In certain cases, in early stages of certain types of cataract, reading is possible without corrective lenses.
  • Sewing or any other occupations that requires detailed focus


There is not particular advice for preventing cataract. When there are indications of cataract appearance we must immediately intervene so that to avoid surgical challenges that a mature cataract might pose. It is recommended to protect our eyes from the sun, even from early age, since there are indications that solar radiation can be connected with the creation of genetic predisposition of cataract. Therefore suitable sunglasses, that absorb the damaging ultraviolet and high energy of sun rays, should be worn during the day. Finally, it should be reminded that cataract surgery is the most frequent and most successful surgical intervention in Medical Science around the globe.
