As we age, it is common to lose our ability to focus on near objects. This condition, referred to as presbyopia, can be easily corrected with multifocal contact lenses. Traditionally, the only option for this condition was reading glasses. However, this can be a difficult solution for people with active lifestyles. Multifocal contact lenses provide multiple prescriptions in one contact lens so that users can see clearly from all distance levels. Unlike bifocal lenses that sharply demarcate vision prescriptions correcting near and far-sightedness, multifocal contact lenses allow for a more gradual transition between prescriptions. This alternative allows for good near and distance vision without the burden of reading glasses.
How Do Multifocal Contact Lenses Work?
A concentric bifocal pattern is a common prescription for people with presbyopia that provides a small circle in the middle of the contact lens for up-close reading surrounded by a larger circle for correcting distance vision. Alternatively, the “up-close” circle can be placed on the outside of the distance correction circle if the patient’s vision requires this type of correction.
Translating designs, or alternating image designs, are another type of prescription for multifocal contact lenses that have distinct zones for near and distance vision but are only available as rigid gas permeable lenses.
Reasons for Needing Multifocal Contact Lenses
By providing two different vision powers, multifocal lenses work perfectly to:
- Significantly improve vision for reading, computer work and driving
- Give you the ability to judge distances more precisely (especially useful if you drive frequently or interaction with machinery)
- May help delay worsening of presbyopia by relieving vision “stress” to the eye’s muscles and nerves
- Enhances peripheral vision
- Allow you to wear sunglasses that block UV radiation
- Prevent eye strain and tension headaches
In addition, multifocal contact lenses are available in rigid gas permeable or soft lens materials designed for either extended wear or one-day disposable wear. If you are over 40, or have been diagnosed with presbyopia, multifocal contact lenses could be the answer for you!
