The basic definition of monovision is the adjustment of one eye for near vision & of the other for distance vision. This means that each eye is operating separately instead of working together. If you were to select monovision, your dominant eye, or the one that would be used to focus on a camera, would become the distance eye & the other would be used for near vision.

How Monovision is Achieved

The corrections used to create monovision can be done:
? Surgically with laser vision correction
? With IOLs (intraocular lenses)
? Traditionally with something like contact lenses

In most cases, your ophthalmologist may recommend trying contact lenses with monovision to see how you adapt to it before choosing permanent monovision through LASIK surgery. If monovision is created using laser vision correction & isn’t well tolerated, it may be reversed by having LASIK treatment on the other eye to make them the same.

How Monovision Works

Even though monovision may sound strange because we’re used to our eyes working together, it can have its advantages. Monovision works because the brain chooses whichever image is appropriate for the task at hand, & ignores or filters out the blurry image from the other eye. This method is one type of vision known as simultaneous vision. For example,
? If you’re reading & need near vision, the far vision image will be filtered out
? If you’re driving & need far vision, the near vision image will be filtered out Most people can easily adjust to monovision in time, but some people have difficulty with it.

Side Effects

There are some reported side effects of monovision, such as:
? Loss of sharpness,
? Decrease in depth perception
? Blurred near vision. People who require very sharp vision for a hobby or occupation may not actually be pleased with monovision results. Monovision may require people to give up a small amount of distance vision to gain close up vision. There’re also reports of seeing shadows when attempting to read small print. To correct some of these problems, people with monovision may need prescription glasses for things such as night driving.

However, the cost of monovision is lower than some other options like bifocal or multifocal implantable lenses.

Monovision may be the solution you’re searching for if you want to preserve both near vision & distance vision, especially if you’re over age 40-45. This is when presbyopia creeps up on us. Presbyopia is stiffening of the lens so that it can not change its curvature so readily in order to accommodate itself to near vision. Reading glasses become necessary.

As with other vision correction solutions, you should discuss monovision thoroughly with your ophthalmologist to determine whether or not you would benefit from it… Dr. Jonathan Davidorf in West Hills, California offers more information about monovision on his website.

If you or a family member is considering vision correction, monovision may be the choice for you… For lots more information about monovision, as well as other types of vision correction, contact Dr. Jonathan Davidorf & the Davidorf Eye Group in West Hills, California.
