What characterizes segmented multifocal contacts?

Segmented multifocal contacts are characterized by having defined sections with visible lines. This design allows for different zones for viewing at various distances, such as near, intermediate, and far. The visible line serves as a clear delineation between the different optical zones, making it easier for the wearer to transition between different focal points.

The presence of these defined sections means that the wearer can quickly identify where to look for different visual tasks, which is particularly beneficial for activities that require varying levels of visual acuity, like reading or driving. This structured approach is essential for those who have presbyopia or other vision issues that require multifocal solutions.

Other designs, such as seamless multifocal contacts, do not have these visible lines and can create a different visual experience that relies more on gradual transitions between prescription strengths.
