I actually have those goggles, but find they don't fit well over my glasses. Know of any pair designed to work with glasses?
I know flux isn't perfect. But as I don't really use my phone much before bed, it seems to work well enough. The glasses could be useful for late night computer work though.
There is a website that sells over the glasses shades for this purpose, but those are way over priced. Most anything orange stands a good chance of working. You can park an incandescent bulb behind one and look at its spectrum reflected off of a CD or DVD. Look for the blue that looks like the sky on a cloudless day. I'd buy over-glasses safety goggles from a store, then test them at home and return them until you found a pair that works.
For $24, you can get enough orange filter gel to make a filter for your 27" screen, then have enough left over for a couple of iPads and several iPhones.
