In the case of human beings, sunlight plays a key role in our lives, being responsible for producing certain forms of vitamin D, which regulates the incorporation of calcium in bones. However, these radiations can also be harmful to health, especially can damage the

In the case of the latter, ultraviolet radiation seems to have a greater incidence, which includes the wavelengths between 150 and 400 nm, although the visible radiation (from 400 to 780 nm.) And the infrared (from 780 to 1400 nm.) They can have negative effects.

In people who already suffer from cataracts, these radiations cause discomfort and glare. The main symptoms of cataracts are:

  • Dazzle
  • Progressive decrease in far vision
  • Cloudy or blurred vision or with spots

  • Avoid exposing yourself to sunlight from 10:00 a.m. to 4:00 p.m. because it is the period in which the radiations are most aggressive.
  • Use glasses or lenses with 99-100% protection against ultraviolet rays. See that they have the CE hallmark
  • Do not use sunglasses if it is not necessary and never do it in dark places, since by forcing the pupil to dilate unnecessarily frequently you can develop a long-term photophobia and become hypersensitive to sunlight.
  • Check at least once a year with the eye doctor.
