Does it matter what direction you put a mag lens in your helmet? One side is curved and the other side is flat. Nothing on the package so I just assumed it doesn't matter but we all know what assumed means.

As a test, before you install it, look through it at something, then flip it over and look again, is the view the same?

My lenses have small writing along the bottom edge, I install the lens so I can read that writing as I look through it. Can't remember what it says, I haven't looked at if for a long time. It will make a difference which way you look through the lens, but not that big a difference because it's so far from your eyeball that the curvature is very slight.

I did look at it both ways and really couldn't see any difference and so I put it in as suggested. Thanks appreciate the help.
