Do Sunglasses Block UV light?

[Longline]

After hours of research I have not found any studies or tests that prove sunglasses block UV light.  Manufacturer's put labels on sunglasses claiming they block UV light .....but when you ask them for there test results they go quiet??

Governments just rubber stamp what manufacturers state in their labels.

There is a simple test everyone can do ( as I have done )

Get a UV flashlight and a credit card.  I used my Visa.  Shine the UV flashlight on the credit card and images will show up only when UV light is present.

On a Visa Card there is a large V behind the word Visa. Then cover the credit card with your sunglasses and see  if you can still see the large V. The expensive brand of sunglasses I tested FAILED.  I could still see the large V

One of the many lies we have all been told!

Maybe try staring at the sun a few hours, please

I think the biggest surprise is that Longline was able to get a Visa.

 

Not a surprise that he has crummy sunglasses though.

You don’t realize there are varying wavelengths these filters (lenses) block right?  I don’t think your experiment is valid lol

What experiments have you done?

Can we have your studies peer reviewed? I think we could all use a good laugh.

Are you using your alien vision again.... have the aliens taught you some x-ray vision tricks.....  can you shoot lasers out of your eyes ..... if you remove your cheap sunglasses?

Or are you just blowing smoke up our ...... well you should know the rest of that phase. 

Roflmao 

Welcome home..... again Longline.

you probably also want to check your UV light as well to see if its not throwing off fake light....these days, you can't trust anything or anyone.

Be silly if you tossed your ray bans because your UV light was faker than your fake glasses.

Does that mean that if you cover half of your head with tinfoil it won’t be affected by the nonsense posted on social media?  Would it still be a nice bright yellow or brown and mushy…?

I've tried the UV flashlight test too, and it does seem like some sunglasses might not block as much UV as they claim.
