What are the risks involved with a single functional eye?

Q: My relative lost the vision in her left eye due to some disease at birth. She has a stone eye fitted. Will seeing through one eye cause excessive load on that eye? Does she have a tendency to develop some complications in her right eye in near future? Will her eye ball movements remain the same? Will this deformity be transferred to her offspring?

A:There is absolutely no chance of excess load on the only eye, and also no risk of any other chance of vision going down if you take care of external causes like injury or infection as for any other person. The only loss is that she cannot have binocular vision or depth perception.. And that cannot be retrieved by any means, so need not go shopping for it.
