Re: Wonder what effect ethanol has on the proteins?
Viagra definitely messes up blue sensitivity causing things to appear off colour/brighter/etc due to interference with red and green light sensing proteins, had personal experience with that one.
Interestingly some older folks with eye problems have found that their symptoms improve briefly probably due to ocular pressure variance, not sure why it would cause one problem and help with another though.
It seems that the effect can be seen as interference with ERG response.
