As far as the need for laser glasses/goggles goes, here is a good laser hazard chart---have a look and draw you own conclusions. http://www.lasersafetyfacts.com/resources/FAA---visible-laser-hazard-calcs-for-LSF-v02.png and also have a read of: https://en.wikipedia.org/wiki/Laser_safety

An excellent source of additional laser hazard info--see: http://www.laserpointersafety.com/menu-safety-info.html

Get a pair of good laser glasses/goggles to protect your eyes
Accidents are accidents and they happen. Accidents with lasers happen so fast there is no chance of correcting to avoid them

An Eagle Pair is the way to go -- see: https://www.survivallaserusa.com/Safety_Goggles/cat1667093_1527285.aspx
Thank you.

Anything melting, glass, gloss surfaces, anything shiny...
Don‘t forget about windows. They may look clear, but they do reflect a considerable amount of light on each surface. If you use tripple glass windows, shining through them gets you at least 6 reflected beams scattering around - probably back to you. Even if 90% of the light passes (which would be a very good value), 10% of 1.5W are still 150mW. You don‘t want this to hit your eyes.

And while we are at it, you may hit someone unseen in the dark outside.

If you eventually think about shining through a window, take the proper precautions.
