Color blindness is most often of genetic nature (i.e., people are bprn with it), but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.

Yes - for about 99% of all people affected by color blindness. On the other side it can also happen when a cricket ball hits hard on your head (really heard about this story) or through aging, chemicals or drugs. Also diabetes, heavy tobacco consume or glaucoma (raise of pressure in the eyeball fluid) can cause weak color blindness.

Yes.
Interestingly, all bulls are colour blind too. So when you see matadors waving a red flag around, the bull is not literally 'seeing red' - it's just pissed off coz there's a prat in a silly outfit waving a flag around. You'd be pissed off too.

most of the time they are born color blind. It is hereditary. or sometimes they could contract color blindness but it is very rare.
