The leading cause of blindness is diabeties, the next is cataracts. Animals are as susectable to both conditions as humans are.
Yes, Crows have very good vision. They have considerably better eye sight than most other Birds, as they can see a wide range of colours and hues from very far away, leaving them with the ability to pinpoint things from far away, hope I helped!
the answer to this very cool question is yes
Probably because animals aren't the same as us. They evolve from other creatures from us and the animals they evolved from may have had better sight than us.
To an extent, yes. Animals lose some of their ability to effectively hunt, but not to necessarily kill. Animals learn hunting strategies from members of the family or by watching others. Some even learn just by doing it. In captivity, animals dont need to use those skills. If an animal were being rehabilitated, the people running the camps would try and make it as "natural" as possible for the animal.
the answer is yes, as the toctis infects the animals retna and travels through the cells to close the naked eye as of wich it dies.
Yes, if the optic nerve is severed, you will lose sight in the eye connected to that nerve. This means that you will lose sight in one eye if only one optic nerve is severed, but vision in the other eye will remain unaffected.
