Cheap sunglasses damage your eyes

As I am walking through the street markets in Thailand, I am bombarded with temptations to buy cheap fashion sunglasses at 50 bath ($1.50). Though they are super cute, I can probably only wear them indoor. Recent studies have shown that, wearing sunglasses without UV protection could cause more damage to your eyes than not wearing sunglasses at all!

Putting on sunglasses causes your eyes to dilate, letting more light in and in the case of sunglasses not offering UV protection, more UV rays as well.

UV radiation from the sun can damage not only the skin of your eyelids but also the clear outer parts of the eye — the cornea and conjunctiva. UV exposure also contributes to the development of certain types of cataracts, leading to burns, blindness, and increases the risk of cancer (Environmental Graffiti).

When you’re choosing sunglasses, look for UV protection details on product labels. Choose sunglasses that block at least 99 percent of UVB rays and at least 95 percent of UVA rays. This level of UV protection is in accordance with guidelines established by the American National Standards Institute (mayoclinic).

So spend a little more on the sunglasses and don’t risk your health for a good bargain!
