Do these exist for gen 5 Prius? I've had them in previous cars and enjoyed the glare reduction and improvement in situational awareness.
I don't know of specific replacement for G5 but there are plenty of add on ones that should do the trick
Toyota makes blue-tinted water-repellent mirror glass* for the gen5, but I don't think there's an OEM convex glass option. However @jtchinoy recently installed a set of mirrors that he said came from Spain(?) that I think had convex sections and maybe blue? I think he said they didn't work because the convex angles were set for a right-hand drive car. He kept the new housings for the turn signals and folding motors, but swapped in his original glass. *PN: 08169-47040 - around $80+SH from Japan As far as aftermarket options, I've got no idea on that front.
