Thanks I love the flip ups even better then my eagle pair.. I can see the dot of my 1w-2w 445nm still but blocks out any blue tint at all.. to me the dot turns white.. but they certainly work well and for 40$ you can't beat it.. OD6+ at 190-532.
Hey Thanks 94z28. I like the flip up ones too especially for aligning optics. they have two sets of od lenses, the main pair letting a little light in and a second flip up pair that completely block the light.
