Is the EyeQue Miniscope safe to use?

The EyeQue miniscope is perfectly safe to use.  While taking the vision test, your eyes are exposed to only the light from your smartphone's screen, which most consumers look at daily.  The process itself is non-invasive.  The miniscope is made from ABS plastic and comes with a soft silicone eyecup that gently fits over your eyes for maximum comfort.
