The problem with cheap sunglasses

 cheap sunglasses   are everywhere. It is a popular popular gift offered by companies that want to look fashionable. They are on sale in all stores, near a beach, as well as everywhere people often go in the summer (theme parks, for example). But you should be very very careful with  cheap sunglasses   because even if they help you keep the sun out of your eyes, they can actually do more harm than good.

The problem is that  cheap sunglasses   do not protect against ultraviolet rays, which can cause problems like eye cancer and cataracts. Instead, they fool your eyes into thinking that it's nighttime when it's not, which causes the widening of the pupils of your eyes, letting in a lot more UV rays than they would not normally do it. This massively increases the damage that the sun can cause to your eyes. Although you may be happy to use them to prevent the sun from dazzling you, if you do so often, you could be very detrimental to your health. If you have a cheap  pair of sunglasses   - or if you get one for free - the best thing to do, all things considered, is to throw them in the trash.

Of course, the opposite of  cheap sunglasses   is not necessarily that of sunglasses. The sunglasses you are looking for are those that offer 100% UV protection, but their price can be very reasonable - and as long as you keep track of where you put them at the end of the day. in the summer, they can last you for decades to come, which makes them even better value. You need to look for some kind of official certification that the sunglasses have passed the UVA and UVB tests, and only buy from a trusted store, preferably an established pharmacist.
