Aren’t lasers high energy? Why would you ever want that pointing into your eye? Why not project regular light?
Edit: never mind above TIL lasers are light and can be dimmed
- pastdiscovery 4y agoCan/has been done before. To make VRDs safe, they need to be dimmed with a filter, but it's achievable.

- once_inc 4y agoLasers are regular light, just all pointed in the same direction. The output of the laser (its capacity) is what makes it "high energy" and the number of photons hitting your retina is directly responsible for any warming of the tissue. A laser capable of just a bit of power, enough to outshine regular daylight by a little bit would be more than enough in most cases to make it feasible without concerns to your eyes damaging.

- tootie 4y agoLaser just means the light is tightly focussed in a beam. It says nothing of intensity or wavelength. Those little pen-size laser pointers run on AAA batteries.
