ever wonder HOW SAFE the sunglasses online are for your eyes? how much UV do they filter?

here is my attempt to find out some information about the reported UV protection amounts reported by sellers. it should not be used as any official results - just to help you get an idea of each pair.

the sun emits harmful rays called UV rays, which take the form of UVA, UVB, & UVC rays. now that the ozone layer is deteriorating, there is less protection between the earth and the suns radiation. this accounts for the rising levels of skin cancer and what SPF lotion is used to protect people from. however, this also adds to the potential damage that can be done to the eyes.

when our eyes are in the presence of bright light, our pupils shrink to allow less light to enter the eye-ball so you can see better instead of getting blinded. on the other hand, when your eyes are in the dark (like behind the shade of sunglasses), your pupils enlarge & allow MORE light (and harmful UV rays) into your eyeball so it can be easier to see. this is why sunglasses should filter out 99% - 100% of UV light.

in this experiment, i have to assume what the numbers mean because the UV meter gives a level of UV detected from 0 -- 15. so i assumed that if it reads 0, that means that it cannot detect any UV rays (and the lenses being tested in front of the sensor filters out 100% of the UV rays, or the maximum amount). when you try a real machine made for this type of stuff, it will actually give you a percentage, not a 0 -- 15 scale. that is a better and more accurate read-out than this method, because here, each number (except for "0") represents a range of percentages (I assume).
i will always take every reading 2 times, to make sure the outcome is consistent. if there is a discrepancy, i will take the reading a few more times just to try to get the best number. first, i use the meter to calculate the UV without any filter as a control (to know the maximum amount at this time & place). then i measure the UV filtration for each pair of a variety of glasses.

so, interpret the results for yourself & i hope this helps!

This is really interesting. I wish it was more accurate though.

@akwardsauce

Play :D

Reeeeeeeewiiiinnndeeeeeeeee

[akwardsauce]

@crapzors ya i guess different ones have different quality...at least this shows that there is SOME uv protection in most fakes...not conclusive, obviously...

[crapzors]

@akwardsauce Damn... I thought the fake ones had low uv protection and that it could be an efficient way to figure you are not buying the fake stuff, oh well...
