Wow. Lots of respect here. Too bad it can't help when having to do quick glances.

I like this before/after illustration: http://blogs-images.forbes.com/andygreenberg/files/2010/12/b... thats pretty cool because while I can see both images and the numbers in them, the second is so much more vivid.

Seems like an idea that's overdue.

I wonder how long until someone invents some glasses that refract just certain wavelengths to be a little higher? Could be very lucrative.

Unless I'm hideously misremembering things, air-glass-air refraction will result in the same wavelength and frequency, just a change of direction.

It just seems to 'change' colours sometimes because its scattering white light.

I'm not claiming I know the science of these things, but I think it's just a matter of time until someone figures out how to do it. Most glasses aren't made of 'glass' now anyhow. This new technique might be ridiculously more expensive at first, but I'm sure it'll catch on. It could literally be a lifesaver for some people.

I can't see the numbers on the left at all. I need to get this app.
