It does look like a female. You can actually tell by the ears and the front legs too.

Actually the oldest female American Toad is said to have been in her mid forties and she passed. So it's thought these toads can live into their forties depending on the care. I'd like to get a male toad in the conversation for a longer lifespan but we will see about that.

As for the eye I agree with taking to a vet to get checked out it's the best way!

Good luck!
