The invention relates to a method for coating eyeglass lenses, in particular for coating the edge of eyeglass lenses by means of a needle metering device or jet metering device, wherein the eyeglass lens and the metering device are moved relative to one another and at the same time a coating material is applied to the eyeglass lens, in particular to the edge thereof, from the metering device. The control data for controlling the movement of the eyeglass lens and/or of the metering device are determined before and/or during the application process on the basis of geometric data of the metering device and geometry data of the eyeglass lens surface to be coated, said geometry data of the eyeglass lens surface to be coated being measured or being drawn from a data store.

A method of manufacturing a colored contact lens including the steps of providing a transparent contact lens having a pupil section and an iris section, the iris section surrounding the pupil section and applying a colorant to the surface of the contact lens. The colorant is applied to the contact lens as an amorphous pattern and covers an effective amount of the iris section of the same. The amorphous pattern provides a lens capable of changing the apparent color of the iris of a person wearing the lens while imparting a very natural appearance.

A method of processing an order request for an ophthalmic lens to be manufactured by a manufacturing device includes the following steps: receiving an order request including at least information related to an ophthalmic wearer's prescription by a first processing device; processing the order request by the first processing device on the basis of predetermined processing rules so as to obtain manufacturing parameters to be applied to the manufacturing device so as to manufacture the ophthalmic lens according to the information included in the order request; sending and storing the manufacturing parameters identified as requiring a further modification to a storing device and sending the other manufacturing parameters to the manufacturing device; modifying the stored manufacturing parameters by a second processing device and sending the modified manufacturing parameters to the manufacturing device.

A computer-implemented method for optical element fabrication with optical scanner feedback includes initiating the optical scanner to obtain an optical measurement of an optical layer of a multi-layer film. A rotational orientation for an optical element that is to be cut from the multi-layer film is then determined based on the optical measurement. The method also includes initiating a cutting instrument to cut the optical element from the multi-layer film at the rotational orientation.

An ophthalmic apparatus includes: a light source; a measurement optical system that irradiates an eye with light from the source and guides reflected light from the eye; a reference optical system that guides the light from the source to use the light from the source as reference light; an abnormality detection optical system that has an optical path length of a predetermined length and to guide the light from the source to use the light from the source as abnormality detection light; a light receiving element that receives measurement interference light being combination of the reflected light from the eye and the reference light and abnormality detection interference light being combination of the abnormality detection light and the reference light, and the ophthalmic apparatus determines whether the measurement interference light is abnormal based on waveform of an abnormality detection interference signal outputted from the light receiving element.

A corrected optical lens includes an inner layer that includes a low stress optical lens and an outer layer that includes one or more corrective layers. The outer layer may be formed on at least a portion of an outer surface of the inner layer by scanning the outer surface of the inner layer, generating a surface characterization file based on the outer surface scan, and 3D printing the one or more corrective layers on the outer surface of the inner layer based on the surface characterization file as input to a 3D printer. The surface characterization file may be corrected based on a particular predetermined contour of the inner layer prior to being input to the 3D printer. The correction may include, for example, reduction of root mean square (RMS) values of deviations of detected peaks and valleys on the surface of the inner layer.

Different users of head-mountable devices have different needs for vision correction. A system can be provided to determine the corrective lenses that are most appropriate for a given user. A dispenser can contain a variety of different lenses that provide different types of vision correction. The dispenser can provide an appropriate one of the lenses, and a user can use the lens with a head-mountable device during a sampling session. During the sampling session, the user can verify that the lens is satisfactory.
