JohnsonLevel and Tool 40-6725 Green Brite Laser Enhancement Kit

I’m a general contractor specializing in framing. This product is useless, and changes nothing aside from looking stupid in them.

The green lasers work better in daylight than red, which is not saying much.The glasses do help sharpen the lines, but a lot depends on the brightness of your beam.Most DIY lasers seem to be limited in how far they can project a viewable beam.The included rectangle target is small, 2.5 x 4 inches, has some foil on the backside to help.It does not seem to help, and finding my beam beyond 15 feet (outdoor shade) is nearly impossible.What is possible however, is a nice big white bucket lid, or light cardboard, anything big and nearly white.Also helps to use the glasses.My laser is the uMeasure Cross Line, projects a great green 40 meter beam indoors, not so much outdoors.FYI: on the physics side of light, longer wavelength greens (and blues) are dispersed more in the atmosphere than shorter wavelength reds. That's one reason we have rainbows (the other reason being water drops).

I can see the green light better with my bare eyes than with those glasses

It arrived as described. The glasses help a little in daylight and obviously don't need them when its darker. If all you need is a little boost, then this is for you

The target is only 2.5" x 4" which is pretty much a waste of money. Hope the glasses work.
