  • Publication number: 20240286240
    Abstract: This relates to a method including: detecting, using an optical sensor, an intrinsic optical feature of a lens member to be positioned on a manufacturing apparatus configured to apply an optical lens manufacturing operation to the lens member; and determining, using a processing unit, the position or orientation of the lens member in a framework of the manufacturing apparatus based on the intrinsic optical feature. The method can be used to position and block a lens member, i.e. a lens blank or a finished lens, on any type of manufacturing apparatus used for the manufacture of an optical lens. The intrinsic optical features have not been intentionally etched or engraved onto the lens member for the specific purpose of determining the position or orientation of the lens member.
