Those glasses interest me indeed and I think I will buy them very soon. I think the Method 7 glasses and the other lamp working/welder glasses are different. Here's my take.
Overview:
Method 7 glasses
*German lenses with "rendition technology"
*Italian frames
*Case
*Cleaning cloth
*Filters UVA, UVB, UVC and Infrared wavelengths
*Corrects color perception
Lamp working/Welder glasses
*Lenses with either special glass or an outer film applied to glass
*Most likely made in china frames
*Filters UV
*Reduces sodium flare
*Some block Infrared wavelengths
So Method 7 glasses are of the highest quality components(Italian frames, German glass etc). Lamp working/welder glasses vary in quality depending on where the parts are sourced from.
Key differences:
Method seven protects against UVA, UVB, UVC and Infrared wavelengths and they corrects color perception
Lamp working/welder glasses protects against UVA, UVB, UVC and sometimes Infrared wavelengths. They reduce sodium flare witch makes it seem like the flame is "smaller" on a torch making it easier to work but they do not change the color of what you see.
Conclusion:
If you want to protect yourself from UVA, UVB, UVC and IR($35 extra most likely) then get Lamp working/welder glasses($65-100)
If you want to protect yourself from UVA, UVB, UVC, IR AND you want to correct your color perception under the HPS light for added perception in determining plant health and identifying deficiencies and/or problems then get Method 7 glasses($200)
I feel like being able to identify a deficiency before it gets too late could easily save you the $200 you spent on the glasses. Just my 2 cents. I'll be ordering them in the coming future to give it a shot.
By the way thanks for posting about the glasses ismokepot. I was eager to check out someones honest opinion that actually has them. Those pictures you posted are incredible!
