Are you a smartphone owner and having trouble catching those ZZZZZs at night? You might have to blame the lack of sleep on your handset; according to the Rensselaer Polytechnic Institute in New York, exposure to the light from a tablet could drop the body's melatonin levels by 23%. For those who ironically slept through high school, melatonin is a naturally occurring substance in the human body...

Interesting. Heard a study/report about this some months before. but what about TV/PC Monitors/Screens? Inflict AMOLED screens the same "damage" as LCD / IPS. Would be interesting to see a bit more about the "techy" side of this study.

Setting quiet hours on an Android devices will prevent notification sound, while still allowing calls to go through in case of emergencies. I would assume iOS has something similar

I work night shift and occasionally fall asleep holding my phone. I wake when I drop it though.

I use twilight (no, not the movie) app to help make my eyes feel better at night. I basically colores the screen red. You might not see a difference at first but you notice it if you try switching back to normal.

I really don't spend lot of time on my phone that is If I'm doing LOTS OF DOWNLOADING media. I also watch my movies on my Xperia phone during lunch time and breaks unless I"m not on my PC but not very addicted too it. But here's a weird thing. When I have my phone turn on with its alarm i get weird dreams. when I don't have my phone on i don't. doesn't that sounds kinda weird?

LCD displays such as the HTC one x are more brighter and emit more light even though its on the lowest brightness its still very bad to look at it when ur in a dark room, causing strain on your eyes resulting in ur retina forcefully focus too much on the screen. On the other hand, a amoled display such as the galaxy s3 are not bright tend more on a darker side giving the advantage to lcd displays in outdoor sunlight visibility, but in a dark room samoled is ur best bet in a dark room but still bad for your eyes but not as bad as LCD displays. My solution for LCD displays is too download night mode keeping the light emitted to stay inside a layer of dark filter. Sorry for the essay guys :)

Get some amber goggles or sunglasses for night. It blocks the blue light and keeps your circadian rhythm from being affected by the light.

Basically looking at a bright screen emulates sunlight so your body still thinks it is daytime and you get screwed over.
