Title: William R. Grovesteen: Innovator in Contact Lens Technology
Introduction
William R. Grovesteen, an inventive mind from West Dudley, MA, has made significant contributions to the field of optical technology. With a remarkable portfolio of five patents, Grovesteen has focused his efforts on developing improved contact lens materials and methods.
Latest Patents
Among his latest inventions is a groundbreaking patent concerning the preparation of a hydrated contact lens. This innovative contact lens composition is characterized by enhanced dimensional stability, making it suitable for the creation of corrective hydrated lenses or eye bandages. The composition includes polymerized random graft copolymers with specific ratios of HEMA, PVP, EDMA, MA, and water. After hydration, the contact lens retains 45% to 65% water.
To further enhance the quality of these lenses, Grovesteen has developed an advanced method for shaping, polymerizing, cutting, and hydrating the lens composition. This method involves using a low-temperature initiator, de-gassing prior to polymerization to eliminate oxygen, and maintaining a controlled reaction temperature for optimal polymerization. A specialized, closed rod-shaped casting mold lined with polyester film is employed in the process, resulting in a polymeric rod that can be cut and polished into the final contact lens shape. Additionally, hydration occurs in a buffered saline solution, ensuring the lens meets pH requirements that contribute to its comfort and performance.
