they block 0 IR.
In fact for any IR they are worse since the VLT is lower your eye will dilate and let more light in.
For green they are great, i get almost nothing on a spectrometer and no reading at all with a LPM or a lasercheck. it will drop a ~300mw beam to well below a milliwatt ( and start burning a hole in the lenses ) That's the dewalt ones I have though. I can't say anything about these.
