The present invention provides eyeglass lenses for vision correction, characterized in that transparent eyeglass lenses include lines which are provided on the eyeglass lenses, block a part of a user’s field of view, and induce a holographic phenomenon in which the lines are placed in a space rather than a plane when the user sees a subject through the eyeglass lenses.

Described are polymerizable high energy light absorbing compounds. The compounds absorb various wavelengths of ultraviolet and/or high energy visible light and are suitable for incorporation in various products, such as biomedical devices and ophthalmic devices. Such devices exhibit a number of desirable properties, including providing wearers with favorable optical quality.

An illumination system adapted for an eyewear that includes a light source configured to emit a first light including a power spectrum having full width at half maximum of less than 100 nm in a first range of wavelengths and a second light including a power spectrum having full width at half maximum of less than 100 nm in a second range of wavelengths, the power spectrum of the first light and the power spectrum of the second light differ from each other, and the light source is further configured to emit pulses of light with a pre-determined time function. The pre-determined time function comprises a plurality of packets, each packet of the plurality of packets being followed by a packet interval, and each packet including a pulse alternation between a pulse of the first light and a pulse of the second light.

A method for treating a patient having a vestibular malady is provided. The method comprises (a) diagnosing the patient as having a vestibular malady; and (b) prescribing eyewear to the patient as a treatment of the vestibular malady, either alone or in conjunction with undertaking vestibular rehabilitation while wearing the eyewear. The eyewear (201) has a first lens (205) which extends over the field of vision of a first eye, wherein the first lens has first (207) and second (209) distinct optical regions. The eyewear imparts vision to the first eye which is characterized by a central vision having a first optical quality and a peripheral vision having a second optical quality.

Near-to-eye displays within head mounted devices offer both users with and without visual impairments enhanced visual experiences either by improving or augmenting their visual perception. Unless the user directly views the display without intermediate optical elements then the designer must consider chromatic as well as other aberrations. Within the prior art the optical train is either complex through additional corrective elements adding to weight, cost, and size or through image processing. However, real time applications with mobile users require low latency to avoid physical side effects. Accordingly, it would be beneficial to provide near-to-eye displays mitigating these distortions and chromatic aberrations through pre-distortion based electronic processing techniques in conjunction with design optimization of the optical train with low weight, low volume, low complexity, and low cost. Further, it would be beneficial to exploit consumer grade low cost graphics processing units rather than application specific circuits.

The detailed characteristics of the red fluorescence of the human lens—that occurs at the seventh decade of life—is recognized as an example of evolutionary photobiomodulation for repair of the retina, and then used as a paradigm for extending current parametric values for reproducible photobiomodulation. The new photobiomodulation parameters involve relative intensities for wavelength bands within the range of 600 nm to 900 nm.

Disclosed is an apparatus and method for combating light sensitivity, or photophobia, for people with low vision. Both the apparatus and method filter particular wavelengths of light associated with photophobia. This filtering is achieved while maintaining a luminance that is acceptable to the user and that maintains contrast. The apparatus of the disclosure is a mechanical filter that can be applied over an electronic screen. The method utilizes software and a filtering module associated with either the CPU or GPU of a computer. The filtering module processes a video signal by eliminating certain targeted wavelengths of light.

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

In one example an automatic false pupil contact lens comprises a body formed from an optically translucent material and a coating on the body formed from at least one of a photochromatic material or an electrochromatic material that, in response to an input, is to change between a first state in which the coating is optically translucent and a second state in which the coating is optically opaque in response to an input. Other examples may be described.

An optical device including an optical substrate providing with an optical filter configured to inhibit transmission of harmful UV and/or blue light wherein the optical device is further configured to allow retinal exposure of an eye to at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 560 nm, preferably of 480 nm to 520 nm.
