The effects of wearing one contact lens: Many of the symptoms you had before getting proper vision correction can return in the unprotected eye, including blurry vision and trouble with depth perception.
You may have issues with your near vision, preventing you from reading small text close to your face assuming the dominant, protected eye has a prescription for distance vision. Summary: Is wearing one contact lens temporarily okay? These variations include:. Mini-monovision: In this variation, a less-than-typical magnifying power is added to the near vision lens. Mini-monovision often is an excellent solution for people who find that standard monovision does not give them the sharp distance vision they desire, and they don't need to do a lot of close-up work or they don't mind wearing reading glasses on occasion.
A good example is someone who spends much of their day driving and little time working on a computer or reading, but wants to be able to read a menu without prescription glasses. Though a person with mini-monovision may need to use reading glasses more frequently than someone who has standard monovision, he or she will be less dependent on readers than a person wearing regular distance contact lenses in both eyes.
Modified monovision: In this variation, a single vision contact lens is worn on the distance eye, and a bifocal contact lens is worn on the near eye. Modified monovision, like mini-monovision, can provide sharper distance vision than standard monovision, while still providing acceptable near vision without reading glasses for many close-up tasks.
The distance power of the bifocal lens also can be adjusted to provide sharper vision at arm's length for tasks such as computer work. The downside of monovision is that some people find it compromises the clarity of their distance vision too much, making distant objects appear slightly blurred.
Others find monovision doesn't provide adequate near vision to give them the freedom from reading glasses they were hoping for. Also, although the two eyes still work together as a team in monovision, it can sometimes cause a slight decrease in depth perception. In standard monovision and mini-monovision, conventional single vision contact lenses — including disposable contact lenses — are used. Presbyopia is the gradual decline in near vision after the age of 40, which is due to loss of elasticity of the crystalline lens inside the eye.
The first sign of presbyopia is the need to hold reading material, especially smaller print, further away than you used to. Eventually reading glasses or bifocals will be necessary to read except in the case of a near-sighted myopic person who may be able to remove the distance glasses to read.
Either way, computer work and reading will become much more difficult with contact lenses if they are correcting the distance vision only. Monovision provides vision so that both eyes still have vision at both far and at near. However, in monovision the dominant eye will have better vision faraway and the non-dominant eye will have clearer vision at near. A monovision contact lens fit consists of fitting the dominant eye with a contact lens for far vision and the other eye with a contact for near vision.
If a prescription is not needed for distance it would be possible to use one contact lens for near. This may seem like a strange method but it actually works very well.
The reason you can get used to wearing a near and distance contact lens is because we all have a dominant eye. Our dominant eye is the one that primarily focuses on an image. The non-dominant eye helps as well but the brain pays much more attention to visual information coming from the dominant eye.
