Does your 445 (OR 300mW+) "hurt" from backsplash with goggles?

Ok so wearing my wraparounds obviously protect with a big fat OD7+

The gap under the glasses allows the intense blue light in. I am white and all the back-splash light from the room is visible just under my cheek bones.

Would you say this is bad for you. It looks amazing, but does feel uncomfortable in a dark room. Now I kinda wish I got the style 60.. (the room is only like 25ft with white walls).
It is much more uncomfortable when lighting a candle up close. :tsk:

How do you guys feel about the back splatter? I feel that it is very unfocused and not too harmful, but it sure is bright!

Im not entirely sure but i would take any chances.. it may damage your eyes over a period of time or something like that. I'd recommend attaching something to the goggles to block the light coming in from underneath them thats what i would do so i don't have to buy a new pair:D

I was concerned about it when I first received my Eagle pairs and glued a couple of pieces of bike inner tube to the bottom of them. If you want Ill try to get a pic to show you? :beer:

Edit: I got really concerned once trying to adjust the focus a 445 laser. I was new and didn't realise the aixiz focus adapters could easily unscrew off the lens. Anyway I kept screwing, because it wasn't focusing, and it fell of. I got a very bright flash under the goggles and decided that was too close for comfort. So I got to work to prevent any more light from getting underneath! ;)

Hope this is not too off topic:

I think I might be the only one here since I have never heard anyone mention this but I have always felt an after effect on the skin of my face for a couple hours afterwards from the reflected light of a 1W+ 445nm when burning up close. Feels a little bit like a mild sunburn and could be that the backdrop behind what I was burning was lighter in color so gave more reflection.

After getting this sensation a few times I kind of lost my interest in burning experiments which isn't a big deal because my main appreciation of lasers is to admire the beam where there isn't a chance for close reflections onto skin.

I might try burning again when I put together a ~850mW 635nm I have been slow to work on. I'm really curious to find out if this slight sun burnt sensation from the reflected light I have experienced is only with shorter wavelengths and is in any way possibly related to the blue light hazard.

Sorry if this is a bit off topic but just thought I might add this. :eek:

Thanks! :D

EMF, what you're saying kind of makes sense cause sunburn is UV radiation and 445nm blue is pretty close to that. And i looked up the blue light hazard and on wikipedia it says humans aren't affected by it but only rodents and other primates. My best guess is that it is basically a mild sunburn.

I've noticed it too, face feels warm.
And yes I think the reflected light off your face will cause damage in the long run, Model 60s for me.

Just thought Id have a look and I found a pic with one of my pairs of goggles ;) You can see the bike inner tube around the base and it completely seals the goggles against light entering from below! I was thinking about starting a thread about it, but never got round to it...:beer:

Neat idea placing the tube on there... Doesn't look too shabby either. :)

Cheers!

I saw the eye doctor (ophthalmologist) earlier this month and was diagnosed with incipient cataracts and macular degeneration. Apparently everyone gets this as they get older. Some people just get it earlier if they spend a lot of time in the sun or play with lasers.

Now I have to wear sunglasses 24/7. Besides filtering out UVA and UVB, they also need to filter out blue light.

Sensitivity to blue light is a symptom of macular degeneration.

For people who suffer from migraine headaches, blue light can also trigger an attack. That's why people with migraines wear the same kind of sunglasses.

If you are also sensitive to bright light in general, I would see an eye doctor. Your regular doctor can refer you. If it's just in the early stages, the treatment is pretty simple: just wear the right sort of sunglasses.

Wow sorrry for the huge delay, (my phone isn't telling me that yall responded :yabbem:)

Very nice touch Grainde!
I have been thinking about these swimming goggle liners, but I would feel horrible gluing them on with some kind of dense non-clear glue/epoxy on these expensive blockers...

I haven't noticed the "skin effect" but if that can happen I wonder what the blue haze under my cheeks could do :eek:

If you can glue to the rubber of the frame it should be fine, but those look a little too small. I glued mine with super glue about a year ago and they are still good. If you use super glue just make sure the glue doesnt come into contact with the plastic lenses...It could damage them. I didnt test it though ;)

Also let any glue you use dry properly before you put them away in the case. This is because some glues give off solvents and other volatile chemicals, which could also damage the plastic lenses. After 24 hrs it should be fine!:beer:
