Ciba Vision Monovision Contacts
Monovision is a technique used to aid those that need help focusing up close. There comes a time in everybodies life when simple tasks like reading, filing your nails, seeing your watch, or anything else up close becomes visually challenging. This is where monovision helps.
In it's simplest form, monovision basically means that one eye (usually the dominant eye) is corrected for distance, while the other eye wears a correction for near vision. Because two single vision contact lenses can be used, you are not limited to only ciba vision monovision contacts.
If you currently wear comfortable distance vision lenses and notice your near vision is no longer clear, simply having your care provider adjust your prescription in your non-dominant eye can be a simple solution. As simple as this sounds, it still warrants a visit to your lens specialist to find the perfect balance for you.
How do you tell which is your dominant eye? There are so many ways to figure this out that your eye care provider my do it without you even knowing. If you are curious for yourself, the easiest way is to take a picture. Which eye did you use to look through the viewfinder? whichever eye you used is your dominant eye.
Once your dominant eye is defined, a simple adjustment to the power of your non-dominant contact lens will give you monovision. The amount of adjustment will depend entirely on what, if any, contact lenses you are currently wearing, your age, and visual expecatations. Near vision challenges, referred to as presbyopia, becomes noticeable in your early 40's and continues to progress very slowly for about 20 years.
If you are an emerging prebyope (about 44 years of age), adding a +0.50 to your non dominant eye may do the trick. However, if you are 54, more add power may be needed. With modern advances in contact lenses, multifocals are the preferred choice for correcting near vision with contacts.
The problem with a straight monovision fit is; there comes a point when your eyes can't merge the images because the focal points are so different. One eye sees great at a distance, the other sees great up close. However, with both eyes open, nothing is clear. This is when a modified monovision is used. A modified monovision fit basically uses the same monovision fitting technique, only with multifocal lenses. Using a modified monovision, everything is clear. Near, far and everything in between.
