Bats can already see in daylight. Some bats actually rely on their sight and live daylight lives. They have wholly different eyes than their nocturnal cousins. It's not just the software, it's the hardware too.
Yes, cats can see very well at night - why can't bats? You do realize that your comment about cats and their fur explains - in a very dramatic way- why you're ignorant remarks about bats and their eyes are so laughable, right? Cats do end up ingesting alot of fur - but they don't get better at digesting it just because this happens. Nocturnal bats -can- see, they do use their eyes at night, but they don't get any better at it just because they do. Similarly, some megachiroptera have wonderful eyesight - they can even see in color, but they still won't fly on a dark night.
I'd like to remind you, since we're doing the normal meandering, that this all began as you attempted to separate environmental from evolutionary. I'm still waiting to hear back on that one - but I'm happy to drive forward and clear up any other misconceptions you have about the subject (which look to be massive) as well.
The particular trouble you seem to be having here, is that you've somehow incorrectly identified a bats nocturnal lifestyle as -the reason- that their eyes did not develop like say - our eyes (or more mysteriously, the cats eyes). You seem to be of the opinion that doing something a whole lot fuels adaptation. Again, both bats and cats do a their thing at night - one has wonderfully developed night vision - the other does not. You seem to think that being able to see better is a simple issue of say -turning on a light-. The notion that bats would be able to see better if they just had a candle in their caves is ridiculous. They would be able to see no better than their biology already allows, no better than they already can - in other words...they wouldn't be able to see any better at all. It's a biological barrier. It's not uniform, because some bats -do- have well developed eyes.....you've put the cart before the horse. The bats with well developed sight have this characteristic not because living a daylight life makes their eyes "work better", but because having well developed eyes allows them to live more successful daylight lives.
To put this a simpler way - in case you still don't understand- no amount of climbing trees will turn you into a chimpanzee - and that's what we're talking about with regards to nocturnal or diurnal bats, and their respective eyesight. Two species in the same order.
