Why you shouldn"t rub your eyes: doctors named dangerous consequences

The common habit of rubbing your eyes can result not just in irritation, but in serious vision problems — up to and including corneal damage and dangerous infections. This warning was issued by ophthalmologists from the University of Illinois at Chicago. This was reported by The Conversation.

As doctors note, itching and an irresistible urge to rub the eyes is one of the most common complaints at ophthalmology appointments. The main culprit is allergic conjunctivitis, which accounts for nearly half of all cases of eye itching.

The mechanism is simple: with allergies, the conjunctiva becomes inflamed — the thin transparent membrane covering the surface of the eye. Allergens trigger the release of inflammatory substances, resulting in itching, redness, swelling, and a feeling of discomfort. Besides allergies, people reach for their eyes due to dry eye syndrome, blepharitis, or irritation of the eyelid skin.

But the main danger lies elsewhere. As specialists emphasize, systematic eye rubbing significantly increases the risk of developing keratoconus — a treacherous condition in which the cornea gradually thins and deforms, taking on a cone-like shape. The result is deteriorating vision and pronounced astigmatism.

"The most serious risk associated with eye rubbing is the development of keratoconus," the scientists warn.

Modern medicine has a treatment method available — a corneal cross-linking procedure that strengthens its structure. However, in advanced cases, patients may need special contact lenses or even a corneal transplant.

In addition, overly vigorous rubbing can cause a corneal abrasion — a painful scratch on its surface. Such injuries open the door to infections and require antibiotic treatment.

Another unpleasant consequence is subconjunctival hemorrhage: due to the rupture of a small blood vessel, the eye becomes bright red. Although this condition usually resolves on its own within one to two weeks, it looks quite alarming. Furthermore, rubbing the eyes promotes the spread of conjunctivitis, especially viral conjunctivitis, which is easily transmitted through the hands.

To manage itching without risking your health, doctors recommend using artificial tears, applying cold compresses, and avoiding contact with allergens whenever possible. During pollen season, sunglasses and the habit of washing your face after being outdoors can help.

Ophthalmologists also caution against drops that promise to "get the red out": they provide only a short-term effect and can provoke side reactions.

If symptoms persist, specialists strongly advise consulting a doctor for the selection of antihistamine or anti-inflammatory medications.
