Title: Chia-Hung Lan and Multifocal Toric Lens Innovation.

Introduction

Chia-Hung Lan is an inventor based in Taoyuan, Taiwan. His patent work includes an intelligent multifocal lens design intended to provide near, transition, and far vision zones within one optical zone.

Latest Patents

Lan is associated with 1 patent, titled “Multifocal Toric Lens.” The invention describes an optical zone with a near vision zone, a transition vision zone, and a far vision zone surrounding the other two zones. The near zone’s add power is negatively correlated with its radius, while the transition zone’s power reduction falls within a range of 0.1 to 0.6 diopters. At the interfaces between the near and transition zones, and between the transition and far zones, the adjoining powers are equal. This design aims to create continuity across the lens’s vision zones.

Career Highlights

Lan is associated with Pegavision Corporation. His patent reflects work on multifocal optical design and the integration of distinct vision zones into a single lens.

Collaborations

Lan’s listed coworker is Yi-Fang Huang. Their association connects the patent work with other contributors in the optical technology field.

Conclusion

Chia-Hung Lan’s “Multifocal Toric Lens” patent describes a zoned lens design that balances near, transition, and far vision, highlighting his contribution to optical innovation.
