Title: The Innovative Contributions of Charles Hayes Powell
Introduction
Charles Hayes Powell is a notable inventor based in Irvine, CA, who has made significant contributions to the field of contact lens technology. With a total of 5 patents to his name, Powell's work focuses on enhancing the safety and comfort of contact lens wearers.
Latest Patents
One of Powell's latest inventions is a leak-proof contact lens container. This innovative container is designed for disinfecting and storing contact lenses. It features a nonporous but oxygen-permeable, water-impermeable liner that creates a continuous barrier layer. This design allows oxygen to escape while preventing water from escaping when the container is pressurized. The container includes a rigid shell that is porous to oxygen and consists of a main body and a cap that can be attached to the upper rim of the main body. Additionally, the container may have a lens holder for supporting a contact lens. The liner can be made of nonporous silicone, while the shell can be constructed from polyethylene or other rigid plastics.
Another significant patent involves compositions and methods using sub-PPM combinations of polyquaternium-1 and high molecular weight PHMB. These multi-purpose solutions for contact lens care provide substantial comfort and acceptability for lens wearers, minimizing corneal epithelial punctate fluorescein staining. The solutions include an aqueous medium, an antimicrobial component, a surfactant, a buffer, a viscosity-inducing component, and a tonicity component. These formulations lead to improved ocular health and help avoid issues associated with contact lens wear.
