Did you know the Multifocal lenses disadvantages & advantages
yet? People with presbyopia or other refractive abnormalities can greatly benefit from multifocal lenses, an advanced option for those who need vision correction at various distances. Multifocal lenses, as opposed to conventional single-vision lenses, combine multiple lens strengths into one lens to provide sharp vision at varied focal lengths.
This sophisticated lens design offers a smooth transition between close and far vision, which is crucial for activities like reading a book or focusing on far-off objects.
For those who need to focus on close objects and distance vision with ease, multifocal lenses—such as concentric multifocal contacts and aspheric multifocal contact lenses—are the perfect option since they can support different prescriptions in a single lens.
Are older and middle-aged people the only ones who should use multifocal lenses?
No. While multifocal lenses are frequently given for presbyopia in adults, they are also prescribed for children, adolescents, and young adults who have particular vision problems that call for multifocal lenses or who have trouble seeing at different distances.

Segmented Bifocal Contacts:
These lenses include discrete near- and far-field vision zones that are divided by an obvious line. They work similarly to bifocal spectacles, which include a top portion for distant vision and a lower portion for close-up work or reading. Those who require precise vision correction at specified distances will benefit most from this kind of multifocal lens.
Rigid Gas Permeable (RGP) Multifocal Lenses:
