I have a condition called amblyopia. Oddly, peripheral vision is as good as the right eye but central vision is canceled by the brain to prevent double vision. Depth perception is an issue but the brain is remarkable and half-sighted people usually can compensate quite nicely. I mount a mirror on my left handlebar and angle it so my good eye can use it. The wrist mirror with Velcro is interesting; I may try that.
