What is a common treatment for diplopia?

Wearing an eye patch on one eye is a common treatment for diplopia, or double vision, because it helps to eliminate the misalignment of visual images that occurs when both eyes are used together. By patching one eye, the brain is forced to rely on the functioning eye, which can reduce confusion between the two images and help the individual regain clearer vision. This treatment can be particularly beneficial in cases where there is a motor issue leading to misalignment of the eyes.

While other options like engaging in eye exercises and surgical interventions may also be appropriate in specific contexts, the use of an eye patch is a straightforward and effective immediate strategy to address symptoms of diplopia by simplifying visual input. Wearing corrective glasses may help address refractive errors, but does not directly manage the underlying causes of diplopia related to eye alignment.
