Needs another functiion
As I'm a very light sleeper, I had to darken the lenses but even then it went off to late in my dreams (about 30 seconds) and hasn't and don't know if it ever will. Another function setting the time less than 30 seoncds would do the trick. Probably the lowest setting could reduced by a factor of 3 or 4 for those of us who are very sensitive to the light, which, as it's red, goes right thru the eyelids.
