Freeform lenses outperform aspheric designs in vision and patient satisfaction

Freeform spectacle lenses (FFLs) offer improved peripheral optics, faster adaptation, and higher patient satisfaction compared with aspheric lenses (ASLs), according to a review of more than 90 studies evaluating modern lens design performance. Findings were grouped into optical performance, visual function, subjective outcomes, and practical considerations to compare ASLs and...
