It would be funny if it got fixed, and he still wore red shades, just because he's spent a lifetime getting used to that, and all the other colors are a bit overwhelming to him, and the monochromatic world he's used to is somehow more comforting and makes him feel 'in control.' (Plus he's afraid of the 'fix' going away, somehow, which is a possibility in a world full of hostile telepaths, etc., so he always carries a spare visor or glasses, just in case.)
