OPTICAL DEVICE FORMING AN ELECTROCHROMIC OPHTHALMIC LENS, SPECTACLE GLASSES INCORPORATING IT AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240045298 titled 'OPTICAL DEVICE FORMING AN ELECTROCHROMIC OPHTHALMIC LENS, SPECTACLE GLASSES INCORPORATING IT AND METHOD FOR MANUFACTURING THE SAME

Simplified Explanation

The abstract describes an optical device that is designed to create an electrochromic ophthalmic lens for the wearer. This device includes at least one electrochromic cell, which consists of a rear shell and a front shell. These shells have transparent electrodes and enclose a sealed cavity filled with an electrochromic composition. One of the shells is made of mineral glass, while the other is made of an organic polymeric substrate. This combination forms a hybrid mineral-organic ophthalmic lens that can be either plano (non-prescription) or prescription lenses for correcting vision.

  • The optical device is designed to create electrochromic ophthalmic lenses.
  • It consists of at least one electrochromic cell with transparent electrodes.
  • The cell is enclosed by a rear shell and a front shell.
  • The rear shell and front shell are made of different materials - one is mineral glass and the other is an organic polymeric substrate.
  • The electrochromic cell forms a hybrid mineral-organic ophthalmic lens.
  • The lens can be either plano or prescription lenses for vision correction.

Potential Applications:

  • Vision correction: The electrochromic ophthalmic lens can be used to correct vision for individuals with different prescriptions.
  • Sunglasses: The lens can be used to create sunglasses that can adjust their tint based on the lighting conditions.
  • Protective eyewear: The lens can be used in safety glasses or goggles to provide both vision correction and protection.

Problems Solved:

  • Limited options for vision correction: The hybrid mineral-organic ophthalmic lens provides an alternative option for individuals who require vision correction but prefer a different material than traditional lenses.
  • Inconvenience of carrying multiple pairs of glasses: The electrochromic lens eliminates the need for carrying separate sunglasses, as it can adjust its tint based on the lighting conditions.

Benefits:

  • Customizable vision correction: The electrochromic lens can be tailored to individual prescriptions, providing personalized vision correction.
  • Convenience: The lens eliminates the need for carrying multiple pairs of glasses, as it can adapt to different lighting conditions.
  • Enhanced comfort: The ability to adjust the tint of the lens based on the lighting conditions can provide improved comfort and visibility for the wearer.


Original Abstract Submitted

an optical device for a wearer intended to form an electrochromic ophthalmic lens, spectacle glasses comprising two such lenses fitted on a frame, and a method for manufacturing such an optical device. the optical device includes at least one electrochromic cell which has a rear shell and a front shell respectively defining for the optical device a backside surface proximal to at least one eye of the wearer and an opposite front surface, the rear shell and the front shell being provided with at least one pair of transparent electrodes and delimiting a sealed cavity filled with an electrochromic composition. one of the front shell and the rear shell includes a mineral glass substrate, and the other one includes an organic polymeric substrate, and the electrochromic cell forms a hybrid mineral-organic ophthalmic lens selected from plano lenses and prescription lenses satisfying a prescription for power correction.
