摘要:
The invention is intended for patients with diabetes, and relates to a type of contact lens by means of which tear glucose level is monitored thanks to a biosensor disposed thereon.
摘要:
A contact lens having nanoparticles integrated within, or deposited onto, the contact lens. A method for altering the optical density and spectral transmission or reflection response of a contact lens. The method includes obtaining a nanoparticle solution having a predetermined concentration. The method further includes exposing the contact lens in the nanoparticle solution for a predetermined period of time. A method for manufacturing a contact lens further includes exposing contact lens material to nanoparticles for a predetermined period of time to alter the optical density and spectral transmission or reflection response of the contact lens material. A contact lens may be formed after the material is exposed to the nanoparticles.
摘要:
A method for molding an optical member (65) from a material of a nanocomposite resin (61) which includes a thermoplastic resin containing inorganic fine particles is provided. The method includes: charging a solution containing a solvent and the nanocomposite resin into a vessel (17) providing at least an optical surface shape (19a) and an opening (12) to an atmosphere, and evaporating the solvent from the opening to solidify and form an optical surface of the optical member into a finished shape.
摘要:
The invention is related to a method for making a silicone hydrogel contact lens having a nano-textured surface which mimics the surface texture of cornea of human eye. A method of the invention comprises creating a prime coating having nano-textures through controlled imbibition and/or depositions of a reactive polymeric coating material and fixing the nano-textures by crosslinking a hydrophilic polymeric material onto the prime coating to form a crosslinked polymeric coating that perserves the nano-textures of the prime coating and provides a nano-textured surface to the contact lens.
摘要:
Le domaine général de l'invention est celui des lentilles à immersion solide pour applications optiques, en microscopie à très haute résolution. La lentille selon l'invention comporte un secteur sphérique (1) limité par une surface plane (11) et un objet (2) de dimensions nanométriques disposé sur la surface plane, au foyer de ladite lentiile à immersion solide. Une couche opaque (3) à la lumière comportant une ouverture centrale (31) de dimensions nanométriques peut être disposée sur fa surface plane, ladite ouverture étant centrée sur le foyer de la lentille à immersion solide. Ce nanoobjet peut être un tube ou un fil de forme cylindrique. La lentille selon l'invention peut être réalisée par des techniques de lithographie.
