Trifocal Lenses at Eye Doctors of Arizona
If you're always taking your glasses off and putting them back on again depending on what you're trying to look at, you may need a type of multifocal eyewear known as trifocal lenses. These lenses offer three distinct corrective fields to ensure that you can see clearly at near, intermediate, and long distances. Here at Eye Doctors of Arizona, we can confirm your need for trifocal lenses and prescribe the perfect pair of glasses.
How Trifocal Lenses Work
Just as bifocal lenses contain both a distance-vision correction and a near-distance correction, trifocals provide separate segments to correct your vision at different distance levels. The main difference is that trifocals include a small third segment for intermediate vision. This distance level is the one you might use to look at your computer screen, consult your car dashboard indicators, or read music on a music stand. The intermediate segment is placed between the distant-vision and near-vision segments, right in the middle of the lens.
Both bifocal and trifocal lenses are necessary to treat an age-related issue called presbyopia. As you enter your 40s, your eyes' lenses become stiffer, making it harder for the focusing muscles to manipulate them. As a result, you may have trouble seeing close-up objects. If you already had trouble seeing distant objects, you now need more than one corrective power in your glasses to compensate. Some people only need two different segments, while others need three. There are also progressive multifocal that offer a smooth transition through all corrective powers, from distance to near vision.
Precision Trifocals from Your Phoenix AZ Eye Doctor
If a comprehensive eye exam and vision test reveals that you have trouble with your near, intermediate, and distance vision, your Phoenix AZ eye doctor at our optometry clinic may recommend trifocal or progressive lenses. While progressive lenses represent the state of the art in presbyopia correction, some people can't get accustomed to some of the aberrations that they introduce, such as a fairly narrow corrective corridor (down the center of the lens) and a "swim" effect that can feel disorienting. If you can't get used to your progressive lenses or if your insurance doesn't completely cover their cost, you may find that trifocals suit your needs better.
