The present invention is an anti-glare and light extinction optical lens for adjusting an incident light to an emitting light, and the wavelength of the emitting light is part of the wavelength of the incident light, the anti-glare and light extinction optical lens comprises an optical carrier and a plurality of opening holes. The optical carrier has an incident surface and an emitting surface. An accommodation space is formed between the incident surface and the emitting surface. Wherein the incident surface is at a distance from the emitting surface. A plurality of opening holes is formed in the accommodation space of the optical carrier. The plurality of opening holes forms an optical tunnel, and each of the plurality of opening holes has a hole pitch from each other. Wherein when the incident light influxes from the incident surface into the accommodation space, the light tunnel filters out a part of wavelength of the incident light and outputs the emitting light from the emitting surface.

Contact lenses incorporate mask lens designs that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the lens; at least one peripheral zone surrounding the center and having a dioptric power that is different than that at the center; and an opaque mask beginning at a radial distance from the center, thereby providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.

Examples of the present disclosure relate to an apparatus and method for near eye display. In some examples, there is provided an apparatus configured for use in a near eye display, the apparatus including: means configured to provide stenopeic viewing; and means configured to reflect an image to a user's eye.

A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

An accommodation assisting lens comprises a lens main body, and dots that are isotropically and uniformly disposed in the lens main body, and in a visible light region, a difference in average transmittance between a dot portion based on the dots, and a non-dot portion other than the dot portion is 2% to 50% inclusive.

A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

An athletics visual aid focus device is disclosed. The athletics visual aid focus device providing horizontal tunnel vision may be worn by athletes to block out peripheral visual distractions. The athletics visual aid focus device may include upper and lower opaque regions disposed to block out peripheral vision along horizontal planes above and below the user's eyes and may provide a lower transparent region allowing the user to position his feet without head movement.

A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

Contact lenses incorporate mask lens designs that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the lens; at least one peripheral zone surrounding the center and having a dioptric power that is different than that at the center; and an opaque mask beginning at a radial distance from the center, thereby providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.

A manufacturing method of a soft contact lens for presbyopia that increases the depth of a focus by forming a light transmitting region and thus selectively blocking incident light upon eyes. A relatively bright vision is provided by forming, at an outside of the light transmitting region, a light blocking region having a certain diameter and being provided with fine holes with a distribution density that increases toward an outer edge of the first light blocking region, while allowing light complementing the lack of light caused by the presence of the light blocking region. A soft contact lens which can be used by users having different corneal topographic pattern is provided.
