SAS Safety 541 1500 Sidewinder Readers Review

These glasses can be adjusted up and down depending on the task when looking through the bifocal or clear part of the lens.

later First, the bifocal lens is so thin you have to bob your head up and down to see anything in your hand. Using it in my shop was a waste of time and took about 30 seconds. I don't know who they designed them for but I'm a medium height male and when I bend over they literally fall off my face. The hands are weak and the overall construction is unimpressive. I bought these to see if they are any better than the 3Ms I had and I will be going back to 3Ms.
