![]() ![]() Being reliant on one eye will not damage the good eye, though you may find it helpful to take regular breaks to prevent fatigue. ![]() You may also find you are unable to work in the same way as before due to becoming more easily fatigued as your brain tries to adjust to making the best use of your remaining vision. Depth perception is essential in judging distance, for example judging the height of steps or kerbs, and correctly coordinating when pouring a liquid into a cup. Loss of depth perception (3D vision) will be an issue for items within three metres. The area of loss is shown to greyed out on the right. The picture below shows how the loss of your peripheral vision may affect what you see. Peripheral vision is important in being able to navigate through your environment the loss of some of this will impact on your ability to do this as well as you used to. The two measurable differences in your vision will be a loss of the peripheral vision to the affected side of approximately 30%, and a loss of depth perception (3D vision). Your visual system will have to adjust to this new level of sight and you will have to learn to trust what you are seeing. You will have to learn to use your vision in a different way and at times this may not be as automatic as before. This will be the case even if the loss of sight is not complete, as the poor sight from the affected eye may ‘interfere’ with the vision of the good eye. Having to rely on the sight from one eye will take time to adjust to both emotionally and practically. Whether it is short or long term, gradual or sudden, it is normal for it to take time to adjust. This may be due to the loss of vision in one eye due to a disease process, or as a result of a need to cover (occlude) one eye using a patch or similar to stop double vision (diplopia). Monocular vision is where an individual is reliant on only one eye for their vision.
