An archaeobacteria(sp?) capable of living under extremely powerful DNA-modifying radiation corrects mutations by error-checking between _four_ identical DNA strands at once, as I remember.
I understand that each sighted person has the retinal ability to perceive a number of UV light wavelengths (the number might be '1', I forget), and that only the UV opacity of our corneas restricts us from seeing them; seeing the patterns bees see on flowers and such. Cornea replacements can bypass this, as could future genetic engineering. Maybe we will all look back at the way things appear now and see our current vision as partially disabled.
