I used to know someone who ran a reptile rescue who had taken in a number of Corns with sight problems over the years. the common factors which she had identified were that they had been kept with UV and were generally (but not always) lighter coloured morphs, missing the black pigment. This is just anecdotal and by no means scientific, but together with everything else, it's a reasonable case against.I just was curious if the lighting would harm the snake or blind it. I just want to use it for aesthetic reasons.
