Larger pupils, lower contrast decrease visual performance of multifocal contact lenses

Key takeaways:

Multifocal and single vision lenses performed similarly in conditions of high contrast and smaller pupil size.

Clinicians need to understand the effect of multifocal designs.

Perspective from Seema Banerjee, PhD, FAAO

When patients wear multifocal contact lenses, visual performance decreases under conditions of lower contrast and larger pupil size, according to a study published in Optometry and Vision Science .

“The growing use of multifocal contact lenses makes it imperative to better understand not only their ability to slow axial elongation but their impact on visual performance,” specifically visual acuity and contrast sensitivity, Jackson C. Dolce , OD , of University of Houston College of Optometry, and colleagues wrote. “Previous studies have not spec
