Isn't staring into your computer screen all the light you need? Everyone (even Apple now) says that the light screws up your sleep cycle. Wouldn't it help with SAD?

It's (probably) enough light to disrupt melatonin production in the evenings, but that doesn't imply that it's enough light to get you to produce Vitamin D etc and help with SAD during the day. Computer screens don't produce much light even compared to a normal bulb.

Good point. I forgot about Vitamin D.

But isn't that produced through exposure to UV, which LEDs don't emit?
