what is a multifocal lens


Multifocal lenses are contact lenses with multiple prescriptions all in one lens, typically for very close objects, normal objects viewed at a distance, and intermediate distances. 1 They are available in two types, bifocals and trifocals 2 , and can be used for a variety of activities such as reading GPS and driving. They can also be used in cataract surgery, providing multiple points of focus and less dependency on eyeglasses and contacts. 3 4 Multifocal glasses, or progressive lenses, provide a smooth transition between distance and close vision. 5
