Eye rubbing is a common, often involuntary response to various stimuli, but repeated, intense rubbing can have severe consequences, including keratoconus and even glaucoma-like optic nerve damage. Ophthalmologists are urging patients, especially children, to be aware of the risks and take steps to break the eye rubbing habit.

Why it matters

While eye rubbing may seem harmless, it can gradually weaken the cornea's structure and lead to serious vision problems over time. This is a particular concern for children and young adults, who may be unaware of the long-term risks and continue rubbing their eyes as a habit or response to conditions like allergies. Raising awareness and providing effective treatment options are crucial to preventing irreversible corneal damage.

The details

Eye rubbing can be triggered by a variety of factors, including allergies, dry eye, stress, and even certain dermatological conditions. The repetitive mechanical stress and inflammation caused by chronic eye rubbing can disrupt the cornea's delicate collagen fibers, leading to a thinning and irregular shape known as keratoconus. In extreme cases, persistent eye rubbing has also been linked to a form of 'eye rubbing glaucoma' that can cause optic nerve damage and vision loss.

  • Experts have recognized the link between eye rubbing and keratoconus since the 1850s.
  • A 1976 study found a significant history of eye rubbing in 75 patients with keratoconus compared to 231 controls.
  • A recent 2026 study in Israel found that patients with allergic conjunctivitis had nearly double the risk of developing keratoconus.

What they’re saying

“While parents have forever told their children not to touch their eyes, 'don't rub your eyes, that's not good for you', they don't fully know the extent of the damage that this might cause.”

— Bibiana Jin Reiser, MD, MBA, Pediatric cornea specialist

“Eye rubbing creates repetitive mechanical stress on the cornea. The cornea isn't designed to tolerate chronic shear and compression forces, especially when this happens over years. That mechanical trauma can weaken corneal structure, disrupt collagen organization and gradually reduce biomechanical stability.”

— Zvi Gur, MD, Principal investigator

“Not a risk factor but the indispensable ingredient. That's why I say 'no rub, no cone' because rubbing may not be the full picture, but if you remove this ingredient, the cornea does not develop keratoconus.”

— Damien Gatinel, MD, PhD, Ophthalmologist

What’s next

Ophthalmologists recommend closely monitoring patients, especially children, who exhibit signs of chronic eye rubbing. Early intervention to address the underlying causes and break the eye rubbing habit is crucial to preventing long-term corneal damage and vision loss.

The takeaway

Eye rubbing may seem like a harmless habit, but it can have serious consequences for vision health. Raising awareness, identifying the root causes, and providing effective treatments to stop chronic eye rubbing are essential steps to protect patients, especially young people, from irreversible corneal damage and vision problems.
