Videos of men shaving or trimming their eyelashes for cosmetic reasons have become increasingly visible on social media over the past year. Some are doing so in the belief that shorter eyelashes create a more masculine appearance.

However, eyelashes play an important role in protecting the eyes. Removing or trimming them can reduce this protection and may increase the risk of debris entering the eyes, as well as irritation, infection or injury.

How eyelashes protect your eyes

Dr Paramdeep Bilkhu, clinical advisor at The College of Optometrists, said, “Eyelashes serve several key functions to keep your eyes healthy – they help prevent dirt and debris, including dead skin cells and sweat, from entering the eyes to keep them comfortable and reduce the risk of infection; and help reduce exposure of the eye surfaces to harmful UV light.

The risks of using a shaver or scissors near your eyes

As they are highly sensitive to touch, this helps to trigger the blink reflex which protects the eyes when an object or threat approaches the eyes. In addition, using shavers near the eyes can result in cuts and nicks to the sensitive skin, or even penetrating injuries where scissors are used. Even the eyelash trimmings can act like an irritant if they get into your eyes, particularly as the tip and cut end may be quite sharp. So by removing, trimming or attempting to remove/trim your eyelashes, you are risking real harm to your eyes.”

What to do if you have already trimmed or removed your eyelashes

“If you have already removed or trimmed your eyelashes, the good news is they should grow back – but this may take many months. During this period, you should take extra care when washing, grooming or applying make-up to avoid products entering the eyes; and consider wearing eye protection when in dusty or outdoor environments.”

If you have cut or injured your eyelid, experience any eye irritation or redness, or if you notice any sudden change to your vision, please contact your optometrist.
