Colorblind Glasses Response

3 things I learned from this article:
- That colorblindness could be restored.
- That glasses had the potential to fix colorblindness and not something more medicinal.
- Non-colorblind people can also see better, more full colors with these glasses.

2 opinions:
- 600 dollars for these glasses is pretty insane.
- 400 dollars is even more insane for people who don't even need them.

1 question - I wonder what would happen if I wore multiple colorblind glasses at once...would I see through walls eventually?
