Designs, strategies and methods to improve biocompatibility of energization elements are described. In some examples, the biocompatible energization elements may be used in a biomedical device. In some further examples, the biocompatible energization elements may be used in a contact lens. The present application especially proposes biocompatible electrolyte formulations, such as electrolyte formulations approximating the composition of a tear fluid or electrolyte formulations encapsulated to decrease an effusion of the electrolyte to an external environnment.

The present invention is drawn to a process of drilling organic glasses, comprising the following steps:

(a) providing an organic glass substrate;

(b) providing onto at least one surface of said organic glass substrate optionally via an adhesive layer selected from the group consisting of pressure sensitive adhesives and hot melt adhesives, a polymer film having an elastic modulus of equal to or less than 3 GPa in at least one direction and a E*h² is equal to or more than 3.5 N in at least one direction, E and h being respectively the elastic modulus and the thickness of the thermoplastic polymer film; and

(c) drilling a hole through the substrate and polymer film by means of a drill.

Method for perfuming a pair of glasses comprising plastic components, wherein the method comprises the following successive steps of: heating at least a portion of the plastic components of the glasses; applying a perfume to the heated portion of plastic components of the glasses; cooling the heated portion of plastic components of the glasses.

A marking apparatus for spectacle lenses according to this invention includes a printing data generation device (H) which generates printing data of a layout mark to be printed on the optical surface of a spectacle lens. The apparatus also includes a printing device (D) implemented by an inkjet printer which prints the layout mark on the spectacle lens in cooperation with a conveyance device (A) based on the printing data. The apparatus moreover includes a UV curing device (E) which cures the ink printed on the spectacle lens. The printing data generation device includes a storage unit (101) which stores image data of the layout mark, and printing condition data including a plurality of printing conditions each corresponding to the surface state of the spectacle lens, and a process unit (100) which generates the printing data based on the image data and a printing condition selected from the plurality of printing conditions.

Aspects of the present invention provide an electro-active lens and method for manufacturing the same that encapsulates liquid crystal using solid transparent optical material using an improved liquid crystal seal feature. The seal feature greatly reduces the visibility of the liquid crystal seal feature in an assembled electro-active lens. The seal feature is also structurally robust such that the electro-active lens can be processed to fit a spectacle frame without disturbing containment of the liquid crystal and without disrupting electrical connectivity to the lens used to alter the refractive index of the liquid crystal, thereby ensuring fabrication of a commercially viable electro- active lens.

Mittels des Verfahrens und der Vorrichtung gemäß der Erfindung werden beschichtete Brillengläser (2) bearbeitet, um an diesen Fügeflächen auszubilden, die ein zuverlässiges Verkleben der Brillengläser (2) mit der Brücke und den Backen einer randlosen Brille ermöglichen. Bei dem Verfahren ist vorgesehen, dass für das jeweilige Brillenglas (2) zwei Bearbeitungsbereiche mit deren Gestalt, Größe und Ort am Brillenglas (2) vorgegeben werden und dass in den zwei vorgegebenen Bearbeitungsbereichen die Beschichtung am Brillenglas (2) lokal durch Bestrahlen mit einem Laserstrahl (30) abgetragen wird. Die Vorrichtung zeichnet sich aus durch eine Halteeinrichtung mit zumindest einer Aufnahme für ein Brillenglas (2), eine Laserstrahlvorrichtung mit einem Laserkopf (54) zur Erzeugung eines Laserstrahls (30), eine Stelleinrichtung (62) zum Bewegen der Halteeinrichtung und des Laserkopfes (54) relativ zueinander in einer Bezugsebene, und eine Steuereinrichtung (68) für die Laserstrahlvorrichtung und die Stelleinrichtung (62), wobei mittels der Steuereinrichtung (68) die Laserleistung, die Relativstellung zwischen dem Laserkopf (54) und dem zumindest einen Brillenglas (2) sowie eine Scanbewegung des Laserstrahls (30) steuerbar sind.
