Laser projector bad for eyes? : r/projectors
Laser diodes produce a very tight beam of light, therefore it is very dangerous to look into even a low-powered laser pointer. However, in a projector, it works a bit differently. In a projector, the tight beam from the laser is scattered by (usually) a phosphor wheel and other optics to distribute it evenly over a large area (i.e. the viewable screen).
