Dry eye syndrome: symptoms, causes and how we can prevent it

Vision is the most important sense we have, since up to 80% of what we perceive is through our eyes. Therefore, we must have good eye health and take care of it. Dry eye syndrome or dryness of the ocular surface is a very frequent ophthalmological problem that can be favored or caused by various factors (autoimmune, environmental, hormonal, toxic, etc.) and affects 5 million people in Spain, representing 11%. of the total population, which only 34% receive treatment.

Anyone can develop this syndrome, but it is true that you are more likely to have it if:

  • You are over 50 years old.
  • You are a woman.
  • Do you wear contact lenses?
  • You do not consume enough Vitamin A (carrots, broccoli, liver) or omega-3 fatty acids (fish, nuts, vegetable oils).
  • You have certain autoimmune conditions, such as lupus or Sjögren’s syndrome.

Symptoms of dry eyes

Among the most common symptoms that can appear in this disease are the following: sensation of a foreign body or grit in the eyes, watery eyes, eye itching and stinging, “eye pricking”, heavy eyelids, “visual fatigue”, photophobia or fluctuating blurred vision. In some cases, there may even be a need to keep your eyes closed. Of all the mentioned the most common symptoms are:

  • Slimy mucus around the eyes.
  • Sensation of having a foreign body in the eye.
