The seemingly harmless habit of rubbing eyes can damage vision

The seemingly harmless habit of rubbing your eyes can pose significant risks to your vision, according to ScienceAlert. While many people instinctively rub their eyes when they feel itchy or uncomfortable, this action can increase the likelihood of infections, corneal damage, and other serious eye conditions.

Ophthalmologists identify allergic conjunctivitis as the most common culprit behind itchy eyes, accounting for nearly 50% of cases. This occurs when allergens like pollen, dust, or pet dander trigger an inflammatory response in the conjunctiva, leading to symptoms such as redness, swelling, intense itching, and small bumps on the inner eyelids. Dry eye syndrome or blepharitis can also cause discomfort that leads to rubbing.

One of the most severe consequences of persistent eye rubbing is keratoconus, a condition where the cornea progressively thins and bulges outward into a cone shape. This leads to irregular astigmatism, resulting in blurred or distorted vision. While treatments like corneal cross-linking can strengthen the cornea and halt progression, many patients still need special contact lenses, and severe cases may necessitate a cornea transplant.

Additionally, vigorous rubbing can cause painful corneal abrasions if fingernails scratch the eye's surface, potentially leading to infection. It can also rupture small blood vessels, causing subconjunctival hemorrhage, which makes the eye appear bloodshot and bruised. Eye care professionals recommend alternatives to rubbing, such as artificial tears, cold compresses, or anti-allergy eye drops. Maintaining good hygiene and avoiding allergens can also help prevent irritation and infection. Persistent symptoms warrant a visit to an eye specialist for timely diagnosis and treatment.
