Geordi La Forge was born blind and yet he can see better than anyone else on the Enterprise thanks to his signature visor.

It may look like a hair clip, and clash with everything in his wardrobe, but as this comic by Caldwell Tanner shows Geordi's visor gives him the extraordinary ability to see what his fellow crewmates wish to remain hidden. And Captain Picard has some 'splainin' to do about that tattoo!
