Was my first thought as well - does f.lux not scratch an itch that a physical pair of lenses does?

f.lux isn't as portable, as it doesn't cover TVs, smartphones, LED bulbs, etc.

You can get, for example, Lux Auto Brightness for Android though. Helps me since I read in bed on my phone before going to sleep.

Edit: the name notwithstanding, it does more than adjust brightness, including filtering color temperature, much like f.lux

GP's point was that glasses do everything. Nobody is going to port flux to your lightbulb, or TV. ;)

Why install N pieces of software when 1 piece of hardware will do?

Maybe not your lightbulb!

I knew someone would post that ;)

Kudos!

Well, I find the app more comfortable than glasses when lying in bed...

Certainly, there are solutions for each, but glasses seem to be the only universal solution so far.

"Twilight" for Android works well for me.
