Depth perception is the ability of the [[visual cortex]] to calculate how far away an object is just by looking at it. Depth perception is a combination of [[accommodation]] and [[convergence]] that occurs when you try to focus on something. Problems with depth perception and resulting vertigo may occur when lenses are changed, because the relationship between accommodation and convergence changes. Wear your [[prescription]] when driving or operating heavy machinery, and consult with your [[optometrist]] if you have problems with depth perception while wearing your prescription. When changing your [[normalized]] or [[differential]] lenses, make gradual changes, and give your visual cortex time to adjust. | Depth perception is the ability of the [[visual cortex]] to calculate how far away an object is just by looking at it.
