Medical Falling asleep with TV on linked to depression, obesity and other issues

What might the effect be on the blind?

Is there a secondary mechanism in the spurring of melatonin production?
Could our bodies actually sense gravity to the degree that we can regulate to the rising and stting sun even though we can't see it?

Just wondering.

-edit, i'm sorry i should have read the posts first. you have all pretty much cover all of that. =/
The result is a severe sleep disturbance. It depends on the nature of the blindness though.

Could it be that fat depressed people are just more likely to watching the TV in bed?

no, the body can sense light on the skin, too, not just through the eyes. this stuff really does mess up peoples' body clocks, and lots of computer work late at night is just as bad.
You don't cover yourself with blankets? About the only part of my body exposed to light would be the back of my neck and one forearm. And what about moonlight, streetlights, nightlights, and clocks?
