About Mono Contact Lenses

Monovision contact lenses may be prescribed by some eye doctors as a means of fixing specific vision problems, such as presbyopia. Monovision lenses help correct this condition, which causes trouble in reading small print and focusing on distant objects, by fitting one eye with a far-sighted lens and the other with a near-sighted lens.

Significance

• Each person has a dominant and nondominant eye. When the far-sighted lens is fitted to the dominant eye and the near-sighted lens is fitted to the nondominant eye, it allows the brain to believe the lens is actually part of the natural eye.

Considerations

• As the lens wearer adjusts to the monovision contacts, he will notice that the correct eye is automatically used pertaining to the distance of the object being viewed.

Effects

• Monovision contact lenses cause each eye to work on its own, which will result in a differing of vision from when the eyes were used binocularly.

Benefits

• Oftentimes, an eye doctor will see the need for a patient to wear only one monovision contact lens, leaving the other eye completely natural. Monovision lenses are also considerably cheaper than bifocal contacts.

Warning

• Monovision contact lenses may result in the loss of depth perception and three-dimension vision, and may not be suitable for those who drive a lot at night.
