The offspring will not be affected by the blindness.
We have to, of course, assume that there is a very slim possibility of the offspring being born blind.
However, the cat was blinded in one eye in a fight, but not from birth.
Outside influence, not genes, caused the cat to be blinded.
So, since genes didn't affect the cat to be blinded in one eye, the offspring will not be affected in terms of blindness by any passed on genes.
