What defines a monovision correction?

Monovision correction is a specific approach to vision correction where one eye is optimized for distance vision while the other eye is focused for near vision, typically for reading. This method is commonly employed for individuals who are presbyopic, meaning they have difficulty seeing close objects as they age, and it allows them to achieve a balanced vision without the need for bifocals or progressive lenses.

By utilizing one eye for distance and the other for near vision, patients can maintain visual acuity at varied distances, which is particularly beneficial for everyday activities such as driving and reading. This strategy takes advantage of the brain's natural ability to adapt and use the eye that provides the clearest image for a given task.

Various alternatives do exist, such as having both eyes corrected for distance or having multifocal corrections, but these do not align with the monovision concept. Monovision provides a simple and effective solution for many people, as it offers a practical compromise between the need for distance and the need for near vision.
