Latest Patents

Among Billard's latest patents is a game-changing design for non-corrective lenses that improves peripheral vision. This invention details a method for modifying the shape of a spheric or toric non-corrective lens blank, aiming to reduce astigmatic and peripheral defects. By utilizing the Gullstrand Formula, Billard establishes a visual axis relative to the lens blank's reference axis, allowing for an offset in the preferred toric lens design. The inner concave surface is then adjusted to enhance optical quality around the visual center.

Another notable patent covers a non-connecting lens blank that integrates an optical function insert. The design features a matrix of transparent material that facilitates the transmission of light. Additionally, the lens blank allows for convenient trimming by visually aligning the geometric placement of the optical function insert. This insert may incorporate a polarization feature, aligned with specific geometric edges, to provide enhanced functionality.
