Severe pain, swelling, tearing and even a temporary reduction in vision: a day in the sun can be pleasant, but the symptoms you may experience if your eyes are too exposed to the sun are certainly not.

According to the Professional Association of Ophthalmologists in Germany, your sunglasses should have a UV400 level to provide sufficient protection against harmful UV rays.

It is also sufficient if your sunglasses say “100% UV protection” or “UV absorption up to 400 nm”. Alternatively, you can try a cap with a protective visor that has a UV index of three.

Sure, spend more on a nicer pair of sunglasses, but don’t assume price means better protection. In fact, even the cheapest pair of sunglasses from the drugstore can have sufficient UV400 protection, according to the American Academy of Ophthalmology.

Also, don’t assume that polarized or dark lenses in your sunglasses will help protect your eye health. Darker lenses don’t mean more protection, the academy says, and neither does polarization, which itself doesn’t provide UV protection but merely reduces glare from reflective surfaces like the sun. ‘water.

While ophthalmologists say the color and level of darkness won’t change how well your eyes are protected, the size of the lens does change because smaller goggles won’t give you as much UV protection as larger ones.

In more southern countries and places by the sea or in the mountains, the eyes are particularly exposed to solar radiation, according to ophthalmologists.

Indeed, a good pair of sunglasses will protect the surface of your eyes from sunburn. But if your eyes have been exposed to too much UV radiation from the sun, you’ll notice it soon.

Sore eyes, swollen conjunctiva, profuse tearing, and temporary reduction in vision are all likely if your eyes get too much sun exposure. However, the symptoms are likely to disappear after eight to 12 hours, according to ophthalmologists.

If you wear contact lenses, ophthalmologists say you shouldn’t just take a break from your usual hygiene rules while on vacation and be sure to pack cleaning and care products in your suitcase.

Even if you don’t plan on wearing glasses, it can be handy to pack a pair. Your eyes can be irritated or dry in different weather conditions and prolonged exposure to air conditioning on the plane or hotel.

In areas where air conditioning systems are common, it’s a good idea to bring a bottle of eye drops with you. According to the BVA, drinking plenty of fluids can also help.

If you rely on eye drops and eye medications, these should preferably be kept in a cool place to avoid heat.
