Auto darkening sunglasses

[Anglerunner]

I am a tacker by trade and I wear shade 5 sungalsses to do my job which work great for what I do. However someone told me that they made auto darkening welding sunglasses which would be even better I'm sure. The only problem is I can't find them anywhere, so I am looking for some help.

Never heard that one before, doesn't mean they aren't out there.

I wear transitions/photogray lens but I don't think that counts.

They have made auto darkening sunglasses for more than 30 years. They are slow to darken and slower to change to light shade. The ones I had never lightened shade to clear. You could install 2"X4" solar auto darkening welding lens in Oxy Acetylene welding googles shown in link. Might work with external shade adjustment knob if it had sensitivity adjustment. I don't think it would work very good.

Flip up lens would be simple and reliable. Shown in link and available as regular glasses.

You would be shortening your eyesight by a considerable length of time, By using any type of shade changing sunglasses. Since the protection offered by the sunglasses no matter whether they are fixed or the transitions style are not intended for welding, cutting, forging, melting, kiln or glass work!
The levels of and types of UV and other visible and invisible radiation from glowing metal, will and does cause cataracts they go by usually the trade names that they be fall the workers potter's, founders, etc.
Here are some basic's (http://digitalfire.com/4sight/hazards/ceramic_hazard_eye_injuries_due_to_radiation_348.h tml) the information is pretty much the same for anybody, that deals in glowing metal, glass or ceramic materials.
You can check the plasma cutting glasses or shields on this forum.
Not trying to scare anybody and you will do what you think you can do. But these are the stone cold facts and what will be the result.

Thanks for the suggestions, the reason why I was looking for auto darkening sunglasses was to save on my eyes so I could go a darker shade when welding and still keep my full line of sight. The is because I work on open bridge beams and seeing where you walk is very important. Other wise I would just wear a shield but it slows me down a lot and production suffers.
