How do Multifocal and Bifocal Contact Lenses Work

Contact lenses have been around for a long time and have come a long way in design and technology. Several different contact lenses are available at Karns Vision Center in Knoxville, TN. Our selection of contact lenses includes multifocal and bifocal lenses. How do these types of contacts work? Let's take a closer look.

What are Multifocal Contact Lenses?

Multifocal contact lenses are designed to correct myopia or nearsightedness. They provide two different optical powers, one for distance vision and one for near vision. This allows the wearer to see clearly both near and far away. Multifocal contact lenses are available in both soft and gas-permeable varieties.

What are Bifocal Contact Lenses?

Bifocal contact lenses are also designed to correct myopia or nearsightedness. Like multifocal contact lenses, they work by providing two different optical powers, one for distance vision and one for near vision. However, bifocal contact lenses are designed for people with presbyopia.

What is Presbyopia?

Presbyopia is a condition that affects the ability to see close up. It typically occurs in people over the age of 40 and is caused by the natural aging process. Bifocal contact lenses are designed to correct this condition by providing two different optical powers.

Types of Multifocal and Bifocal Contact Lenses

Bifocal contacts are considered multifocal as they are available in two prescriptions. However, not all multifocal lenses are bifocals. There are several different types of multifocal and bifocal contact lenses available, including:

Soft Toric Contacts: These contacts are designed to correct astigmatism. They are available in both soft and gas-permeable varieties.

Hybrid Lenses: These lenses are a combination of soft and gas-permeable contacts. They are designed to correct myopia and astigmatism.

Toric Gas-Permeable Contacts: These contacts are designed to correct astigmatism. They are available in both gas-permeable and disposable varieties.

Silicone Hydrogel Soft Lenses: These lenses are made from silicone hydrogel and are designed to provide greater comfort than traditional soft contacts.
