Though it may seem innocuous, rubbing your eyes can inflict significant harm, as advised by medical professionals. Many individuals rub their eyes to alleviate itching, irritation, or dryness. While this may offer immediate relief, it harbors considerable dangers. Dr. Sermed Mezher, a family medicine expert from the UK, recently underscored the perils associated with this common habit and its potential to irreparably harm your vision.
Dr. Mezher noted that the “pop” sound some hear while rubbing their eyes is generally just air moving into the tear duct and isn’t detrimental. However, the act of rubbing itself poses real threats. He emphasized that eye rubbing shouldn't be habitual as it can distort the cornea, the eye's clear outer layer.
Frequent eye rubbing can lead to a condition known as keratoconus, where the cornea might bulge and become misshapen. A healthy cornea maintains a smooth, round form, but consistent rubbing can alter its structure, sometimes necessitating a corneal transplant—a serious surgical intervention—to correct it.
Dr. Mezher provided an MRI scan illustrating the eye's response during rubbing; the pressure applied can weaken the cornea over time. If persistently engaged in, this behavior can result in permanent damage, producing blurred vision, heightened light sensitivity, and complications with contact lenses or glasses.
Rather than rubbing, Dr. Mezher advises identifying the underlying irritants. He explained that itchy eyes often indicate a more serious issue, such as allergies, dust, pollen, smoke, or dryness from screen overexposure. In some instances, old or improperly fitted contact lenses may also lead to irritation.
Treating the underlying cause is preferable to resorting to eye rubbing. For allergens, allergy drops may be necessary; if screen use is the culprit, taking regular breaks is key. Avoiding irritants like smoke or strong scents will also aid in alleviating discomfort. Addressing the source of the irritation can help safeguard your eyes and reduce the urge to rub.
Eye care specialists recommend rinsing the eyes with clean water, using artificial tears, or gently tapping the eyelid as alternatives to rubbing. Maintaining clean hands and avoiding face contact can also minimize irritation.
The doctor’s pivotal message is straightforward: your eyes are sensitive, and rubbing them can have long-lasting repercussions. Monitoring irritation and seeking timely treatment is the wisest approach.
