I really couldn't agree with this more. Reading before you sleep is so important to getting a good night's rest. Using a physical book or an e-ink screen, anything that doesn't emit light itself.

Seriously, invest $150 into getting a good e-reader, if you don't have one already. It's well worth the sleep benefits, potentially even more than a good mattress (for a programmer, anyway).

One thing I personally found useful was f.lux - an OS X app that changes the temperature of your screen when it gets dark outside. Sounds trivial but makes a huge difference.

I use red sunglasses for that (sometimes advertised as "UV protection"). The advantage is that it works on all devices, even analog ones. :)
