How does monovision contact lens fitting work?

Monovision contact lens fitting works by correcting one eye for distance vision while the other eye is corrected for near vision. This method is often used for individuals who are presbyopic, which is a common age-related condition that affects the ability to focus on close objects. The brain learns to adapt to this setup; when the individual needs to see something up close, it naturally relies more on the eye that is corrected for near vision, and for objects at a distance, it utilizes the eye corrected for distance.

This arrangement allows the person to transition between different focal distances without needing to switch lenses or wear reading glasses. It can provide a more functional visual balance in daily tasks, such as reading and driving, compared to other methods that may rely solely on bifocals or multifocal lenses.

Other options, such as correcting both eyes for distance or using the same prescription for both, do not offer the specific benefits of presbyopia correction that monovision provides. Similarly, fitting only one eye with a contact lens does not address the need for bilateral vision correction, which is essential for depth perception and overall visual comfort.
