Description
Thomas Kohnen, Sahar A. Nouri, and Daniel Carson ran a 2023 bench study on halos seen around car headlights with implant lenses. Lenses that fix age-related near vision loss can leave rings of light at night. The team used a lab bench that mimics a far car headlight in dim light.
They tested six smooth-design lenses and ten split-design lenses with varied near powers. Plain single-focus lenses gave the weakest halos. Split-design lenses gave stronger halos than smooth ones. When a lens sat half a millimeter off center, split designs showed lopsided halo shapes. The authors note that patient reports in clinic studies are still needed to link bench halos to real night driving comfort.
