Title: Innovations in Ophthalmic Lens Manufacturing by Randall Pugh

Introduction

Randall Pugh is an accomplished inventor based in Orange Park, Florida, with a notable portfolio of nine patents. His work primarily focuses on advancements in additive manufacturing techniques for ophthalmic lenses, which have significant implications for the optical industry.

Latest Patents

Among his latest patents, Pugh has developed methods for polymeric additive manufacturing of ophthalmic lenses. One of his key innovations involves a method and apparatus for creating articles that correspond with an energy transmissibility image. This technology can be applied to contact lenses or intraocular lenses. The improvements he introduced allow for the repeated application of a monomer according to a pattern that aligns with the energy transmissibility image, such as a grayscale image. His method includes intermittent pinning of the deposited polymerizable mixture, partial curing, and final curing of the mixture. This process enables the manufacturing of a pattern with multiple defined areas, each representing a specific amount of energy transmissibility.

Another significant patent focuses on methods of additive manufacturing of articles that correspond with arrays of data values. This innovation also pertains to optical lenses, including contact lenses and intraocular lenses. The methods involve generating an array of data values and emitting droplets of polymerizable mixture in a pattern that corresponds with these arrays. After the droplets are deposited on a receiving surface, they are integrated and pinned through exposure to actinic conditions. This technique allows for the combination of two or more patterns of droplets to form a combined volume of polymerizable mixture, which is then cured.
