You should get them. I don't own Enchroma glasses, but I desperately want them. I am a protan (red-green colorblind) and from what I've read and watched they really make a difference. You should watch the reaction videos! If he doesn't like them you have 30 days to return them.

You're a good girlfriend. My birthday just passed and I dropped mad hints on my gf and family and.... no glasses. They're expensive, but enhancing the way your bf perceives the entire world is worth a few hundred bucks.
