Reading Glasses Information

As reading glasses provide a plus power that would normally be used to correct hyperopia, many people incorrectly believe they are becoming hyperopic. Those previously myopic may believe they are both hyperopic and myopic, which are mutually exclusive. Whenever changes in vision occur, it is always best to be evaluated by a competent eye care physician to determine the problem exactly.

Anyone who has needed to use readers, as they are often called, knows just how frustrating and irritating presbyopia can be. Many people have had excellent near and distant vision without glasses all their lives, until those dreaded readers become necessary because of presbyopia.

There are currently no reliable and predictable surgery techniques or medications that will outright cure presbyopia, however there are a number of permanent and semi-permanent techniques to deal with the focusing changes and challenges caused by presbyopia. One of the more popular ways to work around presbyopia is with monovision correction. For many, monovision will reduce or eliminate the need for readers, bifocals, or trifocals. The concept of monovision is very simple.

One eye is corrected for near vision and the other eye is corrected for distance vision. The brain figures out which eye to use and when. How to achieve monovision varies, depending upon the patient's current eyesight.

If a person has never needed corrective lenses like glasses or contacts before, then a small amount of myopia can be induced in that person's non-dominan eye. The dominant eye remains uncorrected, as it already provides full distance vision.

If a person already has less than two diopters of myopia, that person's dominant eye can be fully corrected for distance vision, and the non-dominant eye not changed, which already provides good near vision.

People with greater amounts of myopia may have the dominant eye fully corrected to provide good distance vision, and the non-dominant eye undercorrected to less than two diopters myopic for good near vision. A patient who is already hyperopic can be overcorrected into myopia for the non-dominant eye, and the dominant eye either corrected for distance vision, or remain untouched.
