Why frequent eye rubbing can damage your vision and thin your cornea

Frequent eye rubbing can lead to serious corneal damage, according to a Pune eye expert. Dr Sharoon Shitole, a consultant ophthalmologist and managing director at Vencer Hospital in Pune, warns that the clear front surface of the eye cannot handle repeated mechanical stress.

Health Risks

Habitual eye rubbing is strongly linked to keratoconus, a condition where the cornea gets thinner and bulges forward into a cone-like shape. This causes increasing astigmatism, blurred or distorted vision, and sometimes the need for specialised treatment. Dr Sharoon notes that this concern is especially relevant for younger people, as keratoconus often starts during adolescence or early adulthood and can progress over time. Hard rubbing can also cause temporary pressure spikes inside the eye, irritate the surface, and transfer germs or allergens from dirty hands.

Underlying Causes

Persistent itching often points to an allergy, while burning, grittiness, and the urge to rub can signal dry-eye disease. Long hours on digital screens also reduce blinking and worsen surface dryness. Stopping the habit addresses the action, but not the root cause.

Prevention And Relief

A clean cold compress can offer temporary relief from itching. However, recurrent symptoms need an eye check-up. Lubricating drops may help some patients, and allergies might need specific treatment. Warning signs that require an ophthalmic assessment include frequent changes in spectacle power, increasing astigmatism, glare, distorted vision, or worsening sight despite new glasses.

Context

Ophthalmologists treat disorders and diseases of the eye, ranging from simple surface irritation to complex structural conditions like keratoconus. Medical professionals advise treating eye health proactively rather than waiting for vision to become noticeably impaired.
