We get it, you seem to lose about 50 pairs of cheap sunglasses every summer. Your mate's party, Latitude Festival, that wild night out on Friday… no matter what the event is, you come home with your keys, phone, wallet, but always without those sunglasses. The solution is fairly simple: you buy another pair and don't care about the price tag, as they are always as cheap as a six-pack of beer (which you'll also be buying) in any supermarket or petrol station.

The issue with these cheap sunglasses is that – in most cases – they simply don't provide any sort of UV protection for your eyes. Over time, ultraviolet light damages our peepers and can leave us with a vast array of eye diseases. Okay, but cheap sunglasses are better than nothing, right? Nope. Humans naturally squint in bright sunlight and our pupils contract in order to let in as little light as possible. Cheap sunglasses with tinted lenses and no UV protection will trick your pupils into dilating and actually letting into more light and consequently, more harmful UV rays. Now you get the idea.

It's not as black and white to say that cheap sunglasses = bad sunglasses, but anything with a cheap price tag is usually more concentrated on looks rather than protection. Doctors will always recommend purchasing sunglasses with a "UV 400" label, which protect your eyes against UVA and UVB rays. Any doctor who says otherwise should definitely not be trusted.

We hear your complaints: you lose so many sunglasses that you don't want to pick up a more expensive pair. But, could it be that your inability to keep a pair safe comes from the fact that you know, deep down, that these are disposable and hardly need much care? Well, how about treating them with the respect that your phone, keys, and wallet also get? Expensive things generally receive more care from us, so how about looking at a pair with a bit of value, like Oakley, Ray-Ban, or Lacoste. Perhaps then you'll think twice about letting your unreliable mate just "wear them for a bit."

Good to know:

The sun's rays will be at their worst between 10am and 2pm
A cloudy day won't stop UV rays, as these can go straight through clouds
UV rays can bounce off water, sand, and snow, so wearing sunglasses when you go snowboarding or skiing is just as important as at the beach

While we're at it, how about you protect your eyes even more and stop looking at your phone in the dark before bed? Your eyes will thank you for it.
