To improve your depth perception, hold a pen arm's length away and practice repeatedly placing a cap on the pen, suggests AllAboutVision.com. Another exercise to try is extending your arm while holding a small object, such as a pebble or BB, and then placing the object into a drinking straw.
Alternating rolling the eyes clockwise and counterclockwise for a few minutes may help strengthen nerve impulses in the eye and improve depth perception in individuals with weak eye muscles, explains EyeHealthWeb. If one eye is dominant over the other and causing depth perception problems, resting just the dominant eye, or resting both eyes in low light may help improve the condition.
Consulting a vision therapist, or obtaining prescription contact lenses or glasses designed to help resolve depth perceptions issues may also help, informs EyeHealthWeb.
