Itchy eyes can be caused by a variety of factors, and understanding the possible causes is the first step in relieving this annoying sensation.

  • Allergies: One of the most common culprits is exposure to allergens such as pollen, dust or mites. When these particles come into contact with our eyes, the immune system can react causing itching and redness.
  • Dry eyes: Spending long periods in front of a computer screen or in air-conditioned environments can reduce tear production, resulting in dry, itchy eyes.
  • Conjunctivitis: This inflammation of the transparent membrane that covers the surface of the eye can be viral, bacterial or allergic. All of these types can trigger intense itching.
  • Exposure to chemicals: Contact with irritating substances such as smoke, chlorine in swimming pools or cleaning products can cause eye irritation and itching.

How to relieve itchy eyes?

Now that we have an idea of why our eyes may itch, let's look at some strategies to relieve this discomfort:

  • Artificial Tears: If dry eyes are the culprit, using artificial tears can provide immediate relief, restoring moisture to the eyes.
  • Cold compresses: Applying cold compresses to closed eyes can reduce inflammation and soothe itching.
  • Antihistamines: For allergy-related cases, oral antihistamines or anti-allergy eye drops can help control symptoms.
  • Avoid irritants: if you suspect that chemicals are causing the itching, avoid direct contact and make sure to adequately ventilate the spaces.
  • Eye hygiene: Washing your hands regularly and avoiding rubbing your eyes can prevent the spread of germs that could cause conjunctivitis.

When to seek professional help?

Although many cases of itchy eyes can be managed with care at home, it is essential to know when to seek medical help:

  • If the itching persists for more than a few days.
  • If there is severe pain or changes in vision.
  • If the itching is accompanied by yellow or green eye discharge.

In conclusion, itchy eyes can be a temporary discomfort, but understanding its possible causes and taking steps to relieve it can make a difference. Take care of your eyes and enjoy clear vision without discomfort!
