I like the specs on the Fabricator helmet but there is one that has me confused....

Under "Auto Adjusting Lens Shade" it's says that the only helmet from Everlast to do that is the Defender.
What does "Auto Adjusting Lens Shade" mean?

The way I take that is that the helmet is not auto sensing BUT It says "Fast switching time reduces eye exposure to arc rays, and reduces night blindness".

I'm confused!?
