What is a potential disadvantage of using monovision to address presbyopia?

Monovision is a common technique used to correct presbyopia, where one eye is corrected for distance vision while the other eye is optimized for near vision. However, one of the notable disadvantages of this approach is the compromise in depth perception.

Depth perception relies heavily on the brain’s ability to fuse visual information from both eyes. When one eye is focused on near objects and the other on far objects, the brain may struggle to interpret these differing inputs, potentially leading to a diminished perception of depth. This can be particularly challenging for tasks that require accurate spatial judgment, such as driving, playing sports, or navigating stairs.

While monovision can offer benefits such as greater convenience and potentially lower costs, the trade-off in depth perception is a significant consideration. Individuals considering this method should weigh these disadvantages against their lifestyle needs and visual demands to determine if monovision is the right choice for them.
