In at least one person, this has been shown to give enhanced colour vision.

Though there are special glasses available now to CORRECT color blindness, by filtering out (masking) nearby colors that normally prevent perceiving the missing colors. With these new glasses, color-blind people can see colors they never saw before. It is such a life-changing event it often makes people cry when they put on these glasses for the first time.

Now, that makes me anxious for some tetrachromatic folks (those with four color dimensions) to create "colorblind correction" glasses for those of us "color-impaired" (vast majority of us) folks who can only see the three overlapping R/G/B color bands. Though perhaps we do not have impaired sensation, just absent, in which case we will need to wait for direct-neural stimulation to supply such missing or extra perception. We will be
cyborg then.
