List of Affordable Blue Light Blocking Film/screens Alternatives

edited April 2017 in Sleep Hacking

I'm looking for blue light blocking material to cover lights emitted from electronics. Companies sell screens for phones and computers and they seem incredibly overpriced. I'm looking for a low-cost solution that could be cut to fit the desired device. Clocks should be easy, making it fit nicely on a computer may be more of a challenge.

Here are some things I have come up with on amazon. Anyone have any thoughts? Any reason these should not work?

There are lots of options on amazon. Many of the promising ones are marketed as car light decals
