Glad this got bumped since I missed it before.
Like most people here for me it depends on the laser(s), their power, location, and what I'm doing.
Examples when I would wear glasses:
- Burning anything.
- When photographing, or working close to the beam like in most of the photos in
this thread I posted you can bet your ass I was wearing them because there was a fairly good chance I could inadvertently put my face in the beam. (Fairly sure I did at least once too)
-Working around reflective objects.
When I wouldn't:
- Just about any laser under 50mw without reflective surfaces around.
- When I have my argons setup for their maintenance since you'd have to be a moron or try really hard to get hit in the eye even when they're at full power.
- When I have my HeNe lasers setup. With one exception they all are under 4mW so again you'd have to try really hard to get eye damage. Even with my 1145P which is rated at 20+ mW you'd still have to try hard or again be a complete moron.
- When photographing higher power lasers that are SECURED in place and from an off axis position from the beams at a safe distance where accidental exposure isn't going to happen. An example of this would be my
Lasers in the Night thread. I did wear them when I was shooting down the beam of the argon but otherwise I didn't.
It may be a bit hypocritical to say goggles are a must and should be worn at all times then not do it myself but I still think for all new owners of high powered lasers this is a must until they know what they're doing. Once you know proper laser safety and how to properly setup and use your lasers there are many times where you can enjoy using your lasers without them. Until then it's better to be safe than sorry. Let xoul's experience be a warning and lesson to all of us, 'noobs' and 'vets' alike of what can happen when things go wrong and what can happen in literally less than a link of the eye.
