Can rubbing the eyes damage the retina and lead to blindness?

Whether it's after a long day of staring at screens or when we sense a speck of dust, we have all had those moments when we just want to rub our eyes. Even though it could temporarily relieve our symptoms, repeatedly rubbing our eyes can seriously harm our eyes, especially if we do it regularly. At this moment it becomes quite crucial to realize, though, that there may be more serious repercussions than we may initially realize, such as retinal damage. Here are the effects of repeated eye rubbing and how they may eventually affect our vision.


Increased risk of retinal damage


The pressure that rubbing one's eyes puts on the retina—the layer of tissue at the back of the eye that converts light into visual signals—is one of the most well-known hazards associated with it. A 2022 study “Digital Eye Strain- A Comprehensive Review,” has demonstrated that putting frequent or excessive force on the eyes might create strain on the retina. In extreme circumstances, this strain may result in retinal detachment, a dangerous disorder in which the retina rips away from its usual position and causes blindness if left untreated.



Worsening of existing eye conditions



The last thing a person should do if they already have eye problems such as glaucoma or myopia (nearsightedness) is rub their eyes. In particular, increased pressure inside the eye in glaucoma causes damage to the visual nerve. Rubbing the eyes might momentarily boost this pressure, adding to additional damage over time.



Thinning and weakening of the cornea

A disorder known as keratoconus, in which the cornea—the transparent, dome-shaped surface of the eye—begins to thin and protrude outward into a cone shape, is also connected to eye rubbing. In severe situations, this structural change may result in impaired vision and corneal transplant surgery becomes necessary at that moment. People who rub their eyes a lot are more likely to develop keratoconus, according to research

Infection risks and allergic reactions


Every time we rub our eyes, we are transferring germs, dust, and allergens from our hands into the delicate area around our eyes. This can worsen pre-existing allergic reactions and result in infections like conjunctivitis, or pink eye. Although dry eyes or allergies are frequently the cause of the itching and irritation that leads to eye rubbing, rubbing can worsen these symptoms and start a vicious cycle of misery.
