How Do Multifocal Contact Lenses Work?

If you normally wear multifocal glasses, you may find the same convenience and benefits by wearing multifocal contact lenses. Just as in multifocal glasses, multifocal contact lenses include a range of optical powers so you can see clearly, from far to near and in-between. They’re great for reading a menu or playing sports, without having to carry an extra pair of glasses.

At Advanced Eyecare Center in El Segundo, Redondo Beach, and we offer different types of multifocal lenses. Learn more about multifocal lenses and how they work.

What Are Multifocal Contact Lenses?

Multifocal contact lenses are made with different lens powers, allowing wearers to see clearly at varying distances. These contact lenses have multiple prescriptions in one lens, making it easier to switch between seeing close-up, in-between, and far away.

What Are The Different Types Of Multifocal Contacts?

Multifocal contact lenses come in both soft lens and gas permeable lens materials. There are two types of multifocal contact lenses: segmented vision lenses and simultaneous vision lenses.

Alternating vision lenses

Segmented multifocal contact lenses are very similar to bifocal and trifocal eyeglass lenses. These lenses have a zone for distance vision in the central and upper areas of the lens. There is also a zone for near vision in the lower half of the lens. The distance and near zones are separated by a visible line in the lenses.

Simultaneous vision lenses

Simultaneous vision lenses have different zones of the lens that are designated for far and near, and sometimes intermediate, vision. Depending on the object being viewed, you can determine which regions of the lens provide the sharpest vision.

Simultaneous vision lenses come in either aspheric or concentric ring designs.

Aspheric simultaneous vision lenses blend the different powers together across the lens, so there is a progressive change from far to near powers.

Concentric ring simultaneous vision lenses consist of numerous rings with different powers. The rings alternate between far and near vision powers.

If you are considering multifocal contact lenses over multifocal glasses, contact Dr. Hansen to learn more about which type would best suit your eyes.
