Individuals limited by loss of vision in one eye have difficulties in depth perception." "Determining the distance within three feet from the eye is extremely difficult and highly unreliable."
Lossing an eye results in approximately a 25% decrease in the size of the field of view. These will cause problems in eye hand coordination, depth judgments, orientation, mobility, and some activities of daily living such as playing sports, driving, climbing stairs, crossing the street, threading a needle etc. Most people who lost an eye are expected to adapt to their condition by one year with many reporting the loss had not changed their life in any permanent way. A head turn in the direction away from the loss is an expected adaptation and serves to maximize the remaining field of vision. One-eyed individuals can be expected to demonstrate more head movements as a way of enhancing depth perception for eye-hand coordination tasks and accommodation (focusing).

They will suffer from a lack of depth perception.
While one may be able to tell how far away an object is by its relative size their 3 dimensional vision of the real world will be impaired. This is because both eyes transmit a slightly different picture to the brain, the brain processes the differences and allows you to tell how far away the object is.
Try this experiment. Place a cup on the floor 10 feet away. Cover one of your eyes and direct a friend how to move drop a coin into the cup. After a few tries you should be able to understand how the eyes work and what it would be like to not have one.
Note: A person will not see a "black image" from the missing eye because the cells will no longer be transmitting signals to the brain. Instead it appears as if the eye was just closed. In addition their peripheral vision will be impaired on the side they had the accident.

It will be some loss in depth perception but you can still calculate depth very good based on surrounding things and experience.
You wont be able to see 3D images or movies anymore, (well you can see them but the effect isn't there) they are all about having two eyes.
And you will have to turn your head a bit more, but you can practice you good eye to look in directions it is not used to.

Without the normal offset produced by two eyes in slightly different positions (stereopsis) there will be a loss of depth perception. There will also be a change in peripheral vision, owing to the loss of sight on one side.

There will be no depth perception, like when you look down and know the difference in height between the curb and gutter. Or how far away the horizon looks. There will also be loss of 180 degree range, it will go down to 90 degrees and they will have to turn their head more to see everything better.

He will loose the field of vision, which is obvious since he has lost his eyes and more importantly, he will loose the sence of depth perception.. He will not be having the exact idea as to how far an object is away from him..

Yeah definitly the depth perception, his good eye may become stronger to compensate for the missing eye...with a little time he'll adjust to it

my best friend is a guy..he lost his eye as a child when he fell on a stick.he has a good prosthetic eye..which he delights in freaking out people with by popping it out and handing it to someone.not everyone..but ya get the image.
he drives,does intricate mechanical work and is a great marksman with a wide range of weapons.would not know it if you were not told...or gifted with the pleasure of holding the eye for him.....:)

His periforal vision will be reduced drastically, as well as depth perception.

He will have no depth perception.....that is, he will not be able to tell how far away something is.
