Can I Get Into The Army With A Lazy Eye Army Training Info?? Help?

Army training info?? help? - can i get into the army with a lazy eye

I am interested in joining the army, I checked the site but for more information.
I am interested in medicine, medical assistant / nurse. Still unsure?
1. Is there a physical training of the same, no matter what the job insertion.
2. As the training is intense, often not. : (
3. The medical examination - I have a lazy eye, I am here?
4. To avoid the physical education should be in good shape, I saw a training video on you tube looks very intense. Why does not the physical part?
