Travelling and long flights can leave your eyes feeling dry, irritated and fatigued. Dr Himanshu Mehta, Senior Ophthalmologist, ASG The Vision Eye Center, shares simple ways to keep your eyes comfortable and healthy every time you travel.
For many travellers, the focus is on staying hydrated, stretching and keeping skin moisturised while on the move, especially while flying. However, one aspect of health that is often overlooked is eye care. The low humidity inside an aircraft cabin, coupled with prolonged screen time and airconditioning, can leave your eyes feeling dry and irritated by the time you land. Whether you’re a frequent flyer or heading off on your next holiday, a few simple precautions can help keep your eyes comfortable throughout your journey.
Combat The Effects Of Dry Cabin Air
Aircraft cabins have extremely low humidity levels, often below 20 per cent, which causes tears to evaporate more quickly than usual. This can lead to burning, itching, redness and the sensation of having something in your eye.
To help maintain moisture, blink consciously and more frequently, especially if you’re reading or using a screen, as these activities naturally reduce your blink rate. Carry preservative-free artificial tears (eye drops) recommended by your ophthalmologist to provide additional lubrication during the flight.
Avoid Direct Airflow
The overhead air vent may feel refreshing, but direct airflow can quickly dry out the eye’s protective tear film.
Adjust the vent so that it is directed away from your face or close it if possible. Wearing spectacles can also provide a physical barrier against the drying effects of circulating cabin air.
Give Contact Lenses A Break
If possible, wear glasses instead of contact lenses while travelling. Soft contact lenses tend to dehydrate, making them uncomfortable and increasing the risk of irritation.
If you choose to wear contact lenses, remove them before sleeping, even during a short nap. Sleeping in contact lenses restricts oxygen supply to the cornea and significantly increases the risk of eye infections.
Soothe Tired Eyes
A clean, cool face cloth or alcohol-free, fragrance-free wet wipes can provide welcome relief during long travel. Choose hypoallergenic wipes designed for sensitive skin around the eyes, as they help refresh the area without causing irritation.
Reduce Digital Eye Strain
Mobile devices can make a journey pass quickly, but prolonged screen use can place additional strain on your eyes.
Follow the 20-20-20 rule: Every 20 minutes, look at an object around 20 feet away for at least 20 seconds. This helps relax the eye muscles and reduces fatigue.
If you’re watching content on your phone or tablet, reduce the screen brightness to a comfortable level and remember to blink regularly. Studies have shown that blink rates can fall by as much as 50 per cent while looking at digital screens, contributing to dry eyes.
Stay Hydrated
Hydration plays an important role in maintaining healthy tear production. Drink plenty of water before and during your travel, and limit alcohol and caffeinated beverages, which can contribute to dehydration.
Keeping your body well hydrated helps your eyes retain their natural moisture and reduces the likelihood of discomfort.
Some travel essentials fit neatly into a suitcase; others are simply good habits. Looking after your eyes is one investment that pays dividends long after you’ve landed.
