AI Technical Summary

Technical Problem

Existing ophthalmic lenses fail to effectively address myopia progression and presbyopia, often sacrificing visual acuity for efficacy in vision correction.

Method used

Designing ophthalmic lenses with a power profile that minimizes the shape metric of the through-focus curve by incorporating a bump function and adjusting the power profile to flatten the through-focus curve, combined with apodization to refract and adjust light intensity.

Benefits of technology

The lenses provide improved vision correction while effectively slowing myopia progression and treating presbyopia, maintaining better visual acuity compared to conventional designs.
