Would these do as safety goggles?

So... I was searching through the house trying to find some sunglasses to see if they would block my blu-ray. I know these aren't usually sufficient as protection, but I decided to try anyway, just for fun. So I found two pair of glasses. The first pair were useless as safety glasses, as the dot just became a little bit less bright. So I try the other pair, and the dot gets a lot weaker! I've taken some pictures to show the difference in brightness and to hear what you guys think about it. All the pictures were taken with a bit longer shutter time to avoid the flash, so on all three pictures the dot looks brighter than in real life.


This is without the glasses.



With glasses, beam entering in the "front" of the sunglasses, to simulate me getting hit by the laser.



Glasses in front of the camera. Seen from the "back", to simulate how it would look like wearing them.


So, can I use these for protection or are they totally useless?

yeah, some glasses that block UV can also work well for bluray

So short answer and synthesys of what's usually said: better than nothing + don't risk your eyes, buy proper, certified goggles.

Before seriously thinking of using any sunglasses for this purpose, make sure they can take a direct hit at full power for at least 10 seconds! There is a lot of good info on this in the safety section of the forum.

When I took the second shot the glasses took a direct hit for more than 10 seconds and the dot was still very weak. When I shine my blu-ray into the glasses I think I see some kind of fluorescence, that might be why they are working so good.

If you want to get some that you know for sure will protect against blu-ray, check the link in my sig.

The problem is that I don't have any money to buy goggles for :-/

I'm planning to do it in the future, but for now these will do. Btw, is it normal to shine your blu-ray on everything you can to see if it will fluoresce? ;D

I wouldn't go around burning with those goggles. However, judging from the pictures they seem to be ok, especially if you are pointing/making stuff fluoresce in your house, just make sure to keep the beam away from mirrors as a specular reflection would not be something to test out on your eyes. They will also work so you can fine tune the focus of the BR.

That being said I suggest you limit your indoor use, until you can afford a nice set of goggles.
