  • Publication number: 20260061701
    Abstract: A system includes a substrate partially transparent to a curing radiation having an improved light pattern; a photocurable resin on top of the substrate; and a spatial light modulator for illuminating the resin with curing radiation that passes through a diffuser and the substrate, then enters the resin. The improved light pattern is such that each point in the resin is illuminated by light from a set of points in the diffuser covering at least 10% of a surface of the diffuser. The improved light pattern may be improved and optimized to compensate for a distortion generated by the spatial light modulator, a distortion effect of using curved diffusers, a variability of the spatial response of the light modulator, or for a lack of linearity of the irradiance response of the spatial light modulator. Or the improved light pattern may change over time while projected onto the diffuser surface.

  • Publication number: 20260014754
    Abstract: An eyewear lens resin containment system is used to create an eyewear lens. The system may include a first cone-shaped wall attached to an eyewear lens substrate. The system may include a walled substrate having a second cone-shaped wall that is an integral part of an eyewear lens substrate. The system may include a first containment wall printed on an eyewear lens substrate. The system may include a second containment wall manufactured on an eyewear lens substrate. In each case, there is a resin-tight connection between the wall and substrate. In each case, the substrate and the wall are configured to have resin dispensed on them.

  • Publication number: 20250236066
    Abstract: Systems and methods for lens creations are disclosed. The method includes initiating light transmission from a light source through a diffuser into a container holding resin and a substrate. The light transmission is performed according to an irradiation pattern wherein each point in the resin is illuminated by at least 10% of the diffuser. This causes a lens to be formed. To achieve this illumination, at least 15% of the diffuser receives light from the light source. Further, a diameter of the diffuser is greater than or equal to a diameter of the substrate. The system performing the methods includes a polymerization apparatus and may include a resin conditioning and reservoir apparatus, a metrology unit, a resin drainage apparatus and an optional postcuring apparatus.
