Understanding the Features of Bifocal Lenses
Bifocal lenses integrate a zone for seeing distant objects (distance vision zone), a zone for near objects (near vision zone), and an intermediate zone for objects in between.
However, due to their design, bifocal lenses have an area where users may experience “wobbling and distortion,” causing aberrations and blurry vision. Some people find it difficult to use or adapt to bifocal lenses because of the wobbling or distortion entering their field of view.
Recent Advances in Multifocal Lenses
Multifocal lenses have recently seen significant design improvements, greatly enhancing comfort compared to traditional bifocals. Developed based on neuroscience, these lenses provide significantly improved usability and adaptability.
Moreover, individually optimized lenses designed according to frame shape, face shape, and each wearer’s prescription have been developed and incorporated into the latest multifocal lenses.
