We’ve all been there – a long day, staring at screens, or maybe even battling with seasonal allergies, and suddenly, we find ourselves rubbing our eyes. It’s an almost instinctual response to relieve discomfort, dryness, or itchiness. However, what many don’t realise is that this seemingly harmless habit can have lasting consequences for eye health. Rubbing your eyes might feel satisfying at the moment, but the potential damage outweighs any temporary relief.
Here’s why you should think twice before giving in to the urge.
Risk of eye infections
Our hands come into contact with countless surfaces daily, collecting bacteria, viruses, and allergens. When you rub your eyes, these microorganisms can easily transfer to the sensitive eye area, potentially causing infections such as conjunctivitis (pink eye). Conjunctivitis is not only uncomfortable but also highly contagious. Additionally, rubbing can cause irritants to lodge deeper into the eye tissue, which could exacerbate allergies and make infections more severe. Eye hygiene is essential, and avoiding eye rubbing is one of the best ways to keep infections at bay.
Increased risk of corneal damage
The cornea – the transparent front part of the eye – is essential for clear vision. When you rub your eyes with any force, you risk causing microscopic tears in the corneal tissue. Over time, excessive eye rubbing can lead to more severe issues, such as corneal abrasions and, in some cases, keratoconus. Keratoconus is a condition where the cornea thins and begins to bulge outward, affecting vision and often requiring specialised treatment like contact lenses or even surgery. For those with pre-existing eye conditions, the risk of corneal damage from eye rubbing is even higher.
Worsening of dark circles and puffiness
If you’re concerned about dark circles, rubbing your eyes isn’t helping. The skin around the eyes is delicate and repeated rubbing breaks down the tiny blood vessels beneath the skin’s surface. This can cause or worsen dark circles, making you look more tired. Additionally, eye rubbing increases blood flow to the area, which can lead to puffiness and swelling, especially if the rubbing is frequent or vigorous. Long-term, this habit can affect your skin’s elasticity, leading to wrinkles and fine lines.
Triggering eye allergies
For many people, rubbing the eyes is an attempt to alleviate itching and irritation caused by allergies. However, rubbing can actually worsen the allergic reaction by increasing the release of histamines in the eye area. Histamines are chemicals that the body releases in response to allergens, causing inflammation, redness, and itchiness. When you rub your eyes, you may be setting off a cycle that makes allergy symptoms worse rather than better. Instead, eye drops specifically designed for allergies can offer relief without the risks.
Increased eye pressure
When you rub your eyes, especially with a lot of force, you put significant pressure on them. This increase in intraocular pressure can lead to temporary changes in vision and, if sustained or frequent, may pose risks for individuals predisposed to conditions like glaucoma. Glaucoma is associated with increased eye pressure and can lead to optic nerve damage and irreversible vision loss if untreated. While a single eye rub won’t cause glaucoma, regularly putting pressure on your eyes can lead to long-term damage.
Weakened blood vessels and red eyes
Rubbing can cause the tiny blood vessels in your eyes to break, leading to bloodshot eyes. While this redness is usually temporary, repeated strain and burst blood vessels can affect the overall appearance of the eyes and increase the likelihood of irritation. Frequent rubbing might also weaken the blood vessels over time, making them more prone to rupture and leaving the eyes looking red and tired.
Closing thoughts
Rubbing your eyes may seem like a harmless habit, but the potential risks make it a practice worth breaking. Eye health is essential to overall well-being, and taking preventive steps is key to protecting it. Avoiding eye rubbing, practising good hygiene, and using proper eye care can make a huge difference in maintaining your vision and appearance.
So the next time you feel the urge to rub your eyes, remember that the short-lived relief isn’t worth the long-term risks. Instead, reach for eye drops or try one of the alternative methods suggested above. Your eyes will thank you for it!
