In optical terms, what is ‘monovision’?

Monovision refers to a method of vision correction where one eye is corrected for distance vision while the other is corrected for near vision. This approach is often used in individuals who require vision correction for both near and far distances but prefer to avoid the use of bifocals or progressive lenses. By utilizing monovision, the brain learns to adapt to using each eye for different tasks, allowing for clearer vision at varying distances without the need for multifocal lenses.

This technique is particularly popular among contact lens wearers and those who have undergone refractive surgery, such as LASIK, as it can maximize utility and comfort. The other options focus on specific treatments or enhancements that do not align with the fundamental concept of monovision, making them unrelated to this method of vision correction.
