01

Key Findings

  • 01Progressive addition lenses (PALs) offer a wider range of clear vision across multiple distances.
  • 02PALs generally provide better visual acuity and functional vision for everyday tasks compared to bifocal lenses or monovision.
  • 03While contact lens options exist, spectacle-based progressive lenses are often preferred for their comprehensive visual correction.
02

Application

Design takeaway

When designing for presbyopic users, prioritize optical solutions that mimic natural vision by providing clear sight at all distances, with progressive addition lenses serving as a benchmark for comprehensive correction.

How to apply

When developing or evaluating optical devices for individuals experiencing presbyopia, consider the performance metrics of progressive addition lenses as a benchmark for user visual experience and functional capability.

Project actions
