Sorry, I didn't now it. I think it's correct when talking about dots, not beams. Anyway, as said, this has been discussed at length, so no need to bring it back.

Beams should be the same too. Remember, a beam is an intense light source, and your photopic vision doesn't "switch off" since the surrounding environment is dark. The type of vision that is engaged depends on the type of light you're viewing. Laser beams are bright - usually

Even when I smoke a room up, I can just hardly see the beam while I can easily see the beam on a 1mw red laser, however, I blame my eyes.
Let your eyes become dark adapted. That will take as much as 30-45 minutes even longer to become fully adapted. In your case visual acuity is secondary.
