Birthday presents are rarely life-changing, but this man's gift to his colourblind friend is.
YouTuber HaightNLife gives his friend a pair of Enchroma glasses, which correct his colourblindness, and allow him to see colours properly for the first time. He can finally see his purple-haired friend's true hair colour, appreciate art, among so many other things.
The cost for the glasses the man is wearing start at around £215 ($330), but of course, his reaction is priceless.
