Why is excessive rubbing of eyes dangerous?
We’ve all heard it from our mothers: “Don’t rub your eyes!” But few knew just how serious that advice really was.
In the Winelands District of Cape Town, allergies are common, especially ocular allergies that cause extremely itchy eyes. While rubbing might feel relieving, it comes with a serious risk.
The Hidden Danger: Keratoconus
The cornea (the clear front part of the eye) is made up of delicate collagen fibres, particularly vulnerable in children. Excessive rubbing damages this structure, significantly increasing the risk of developing Keratoconus.
Keratoconus is a progressive condition that causes the cornea to thin and bulge into a cone shape. It typically begins in the teenage years and leads to:
Progressive decline in vision
Glasses no longer working
Need for rigid contact lenses to improve sight
In advanced stages, a corneal transplant may be required
A corneal graft involves transplanting a donor cornea to save the eye from severe damage. While it may restore some vision, it’s a major procedure and not one without risks.
