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 interact with machinery)
May help delay the worsening of presbyopia by relieving vision “stress” on 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!
