It could also be due to our healing ability being more about quickness than completeness. For example, many animals regenerate inner ear hairs, while we cannot. So we lose range and acuity over time and from injury, while they just recover. Humans have some form of that for taste and smell receptors though, so tongue burns won't usually cause permanent loss of taste.
As to vision, a bigger issue is that human vision is insanely acute for a mammal, and only bested by a few raptors. We don't even have many "blue" receptors in and around our mega-sharp fovea, because those wavelengths are a hint damaging too.
