Below is a photon-accurate comparison of two different multifocal contact lens designs. One represents a softer design, similar to an aspheric lens, with many gradual changes in power across the lens. The other represents a harder design, characterized by fewer, larger, and more abrupt power transitions. For a deeper explanation of this concept and how the simulation was created, please refer to the linked blog post.

The Future of Multifocal Contact Lenses (Inspired by the Past)

If you are frustrated with progressive glasses, or you want to wear contact lenses but are tired of not being able to read with them, you have probably been told that multifocal contacts “just don’t work.” It may be time to reconsider. Some newer multifocal designs lean on an older optical principle, and that shift appears to be creating a genuine step change in how well these lenses perform.
