8 results about "Vision disorder" patented technology

Illustrative methods and devices for providing stimulus to the eye to treat vision disorders. Systems and methods for testing thresholds and configuring the stimulation for a patient are provided. Various examples may include therapies for vision disorders that can progress to blindness, such as macular degeneration or other diseases and disease processes.

A UV-laser-based system (UVL-LVC system) for correcting the impaired vision of a patient's eye has a UV-laser source, which emits laser radiation to treat the patient's eye, and imaging optics for focusing the laser radiation onto the cornea of the patient's eye. The imaging optics allow a detection of a reflection of radiation, which is emitted onto the cornea of the patient's eye with the imaging optics and is at least partly reflected by the cornea of the patient's eye back into the imaging optics at an acceptance angle χMax of at least 2.5°. Additionally a method for centering a UVL-LVC system is disclosed.

Illustrative methods and devices for providing stimulus to the eye to treat vision disorders. Systems and methods for feedback relating to the stimulus itself as well as the effect of such stimulus on the patient are provided. Various examples may include therapies for vision disorders that can progress to blindness, such as macular degeneration or other diseases and disease processes.

Eyeglass set, comprehensive a) a pair of glasses (1) i) with at least one lens (4), ii) with a nose cutout (6) for the nose of a glasses wearer, and iii) with a head-holding device (9) connected to at least one lens (4) for holding the glasses (1) on the head of the wearer, b) a nose support element (2) that can be detachably and magnetically attached to the glasses (1) for supporting the glasses (1) against the nose of the wearer when the nose support element (2) is mounted, and c) a vision correction component (3) that can be magnetically attached to the glasses (1) and which i) has at least one corrective lens (24) for correcting a visual impairment of the spectacle wearer, and ii) has its own nose support (26) to support the glasses (1) against the nose of the wearer of the glasses when the corrective lens (3) is mounted.

The present disclosure relates to methods and systems for evaluating vision in subjects, particularly those with low vision or visual impairments. Further provided herein are methods and systems that enable effective testing to monitor and evaluate changes in a subject's vision over time.

Methods, kits, and material compositions for use in correcting eye conditions are disclosed. This involves a selected three-dimensional patterning of the user's corneal surface. The pattern is selected to provide an optical effect according to a given visual impairment of the user. A dispersant in liquid (aqueous solution) form containing nanoparticles is applied onto the selected three-dimensional pattern, thereby dispersing the nanoparticles in the incision areas of the pattern. The nanoparticles include biocompatible protein-based nanoparticles. The dispersant may also be used as eye drops, thereby allowing the nanoparticles to occupy etching areas on the cornea, thereby functionalizing and maintaining the visual correction effect of the pattern on the eye condition. The disclosure further provides methods and kits for ablating corneal tissue in a selected pattern by using visible-spectrum light.

The present invention relates to a photosensitive ring oscillator, its preparation method, and a flexible artificial retina. Specifically, the photosensitive ring oscillators (PROs) based on 2D semiconducting materials have been fabricated on flexible biological compatible substrates, which transduces light information into electrical pulse signals directly, propagating through the optic nerve. The output oscillating frequency varies quasi-linearly with the change of light intensity. The flexible electronic devices can be used as implantable biomimetic retina for artificial vision to recover the sight sense for sight-handicapped people.

The system according to this embodiment aims to provide early detection and countermeasures for vision loss and visual impairment. [Solution] The system according to the embodiment comprises a collection unit, an analysis unit, a detection unit, a notification unit, and a suggestion unit. The collection unit collects visual acuity test data, eye photographs, and lifestyle data. The analysis unit analyzes the data collected by the collection unit to understand the individual's visual state. The detection unit detects abnormalities based on the data analyzed by the analysis unit. The notification unit notifies the abnormalities detected by the detection unit in real time. The suggestion unit proposes preventive measures and corrective measures based on the abnormalities detected by the detection unit.
