DilatoLighting

 lights which are only as light as your eyes want

My new house has got dimmer switches which 'warm up' from low light to full brightness when you switch them on, which is a charming, if unoriginal spin on the dimmer.

Enter dilatolighting, which comes complete with a sensor to look at how dilate your eyes are before judging how bright the lights should come one. Therefore, if I enter the room from complete darkness, it warms the lights up slowly, wheras if I turn on the light and it's really bright (my pupils aren't dilated much) then it flips straight on to full beam.

in case you're interested it looks at the dilation of the person turning on the switch.

       Do you have to look into the switch to turn on the light? How does it sense how dialated your eyes are?

       it measures their dilation, using a low powered laser, or similar.

       So whats wrong with the present dimmer switch solution? And what if you have guests over and there's more than one person in the room?

       [lbaf] that's why it focusses on the person that flicks the switch. Present dimmer switch option is annoying when it's day time and the room is in pitch darkness (there are no windows).

       Which drugs would you be on that allow your eyes to dilate so slowly that you are out of sync with the room? Watch someone (someone not on drugs) as they blink or look around. Their eyes adjust quite quickly. The dilator system is counting on a phenomenon that does not exist. If you are in a dark room, your eyes are going to be dilated. Again, assuming no heavy sedatives.

       This needs a way to adjust,trim, for the differences in dilation between people. I've noticed the variation in people's eyes can be dramatic.

       Lighting that monitors those in the room and adjusts for the direction they are looking has been preheated in fiction for fifty years or more.

       I want the pupils in my eyes to have as much exercise as they can get. In biology it's typically use them or loose them, and I only have one set.
