How Does Pupil Optimized Design Work in Acuvue Oasys Multifocal?

Pupil Optimized Design is the optical technology at the core of Acuvue Oasys Multifocal — distinguishing it from older-generation multifocal designs. It is what enables this lens to deliver clearer, more consistent vision at near, intermediate, and far distances across a wider range of wearers.

The Core Challenge of Multifocal Lens Design

All multifocal contact lenses must incorporate multiple prescription powers within a single small lens. The challenge is that pupil size varies significantly between individuals and changes with age and lighting conditions. A multifocal design calibrated for one pupil size may perform poorly for a wearer with a different pupil profile — causing blurred intermediate vision, halos, or difficulty adapting.

How Pupil Optimized Design Solves This

Pupil Optimized Design tailors the optical zone configuration to two variables simultaneously: the wearer's refractive error (sphere prescription) and the wearer's age — which correlates with typical pupil size and the degree of presbyopia progression. Because pupil size decreases with age, a 48-year-old with early presbyopia has meaningfully different pupil characteristics than a 64-year-old with more advanced presbyopia. Pupil Optimized Design accounts for this by adjusting the size and proportion of near, intermediate, and distance zones for each prescription-age combination — with 100% of parameters optimized for the specific wearer's pupil behavior.

The Add Power System

Your eye care professional will determine your appropriate add power based on your age, near vision needs, and presbyopia progression. Consult your eye care professional if you are experiencing difficulty with near vision alongside your existing prescription.
