A contact lens includes a central region, an annular region and a peripheral region. The central region includes a central point of the contact lens. The annular region symmetrically surrounds the central region. The peripheral region symmetrically surrounds the annular region. The peripheral region includes at least one color pattern portion. The annular region includes at least one power of critical point.

A motion sickness prevention eyewear presents a demarcation line in a field of view in a lens assembly. The demarcation line varies relative to the orientation of the eyewear to present a visual depiction corresponding to a natural horizon. The eyewear includes at least lens assembly that has an interior cavity defined between an inner lens, an outer lens, and a sidewall defined to join the lenses around the periphery of the lens assembly. A volume of liquid is carried in the interior cavity. The volume if liquid is responsive to changes in the orientation of the eyewear relative to the horizon.

A contact lens according to an embodiment of the present disclosure includes: a lens unit to be placed on an eyeball; and an optical device that is mainly provided in a circular region opposed to a pupil that becomes small by contraction in a case where the lens unit is placed on the eyeball, and provides an action that is different from an action of the lens unit to light entering the eyeball.

An eyeglass assembly includes a frame and a lens assembly attached to the frame. The lens assembly includes a body, a connecting portion extending below the body, and a glare reducing portion extending below the connecting portion. When the eyeglass assembly is worn by a wearer, the glare reducing portion is located below a vision level of the wearer.

A spectacle lens includes an activable optical filter having at least an electrochromic device and being configured to be actively switched between at least three configurations. In the first configuration, the activable optical filter is uniform. In the second configuration, the activable optical filter attenuates selectively light from a localized light source. In the third configuration, the activable optical filter is uniform. Furthermore, the chromaticity difference Chrom between each of the configurations is smaller than or equal to 20.

A colored glass lens for eyeglasses and a method for making such lens, where the lens includes a front glass wafer and a rear glass wafer having a convex surface connected to a concave surface of the front wafer, at least one of either the convex surface of the rear wafer or the concave surface of the front wafer being colored, and a layer of glue interposed between the surfaces for bonding the front and rear wafers to each other.

An optical lens having three discrete filtering zones is disclosed for eyeglasses. The eyeglasses can be worn two to four hours prior to bedtime to reestablish a proper circadian rhythm even in the presence of artificial evening light. The three discrete filtering zones can differently filter green or blue light.

A contact lens includes a central region, an annular region and a peripheral region. The central region includes a central point of the contact lens. The annular region symmetrically surrounds the central region. The peripheral region symmetrically surrounds the annular region. The peripheral region includes at least one color pattern portion. The annular region includes at least one power of critical point.

An eyewear includes an eyewear frame; and two lenses held in place via the eyewear frame, each of the two lenses having a top portion composed of a clear polycarbonate; and a bottom portion integral with the top portion and composed of an orange polycarbonate; the bottom portion absorbs blue light and the top portion allows all light through.

An apparatus is provided to create a focal zone for mindfulness meditation. The apparatus includes a first member extending between a first edge and a second edge, the first member having a translucent portion, a first elongated side member attached adjacent the first edge of the first member, and a second elongated side member attached adjacent the second edge of the first member, the first and second elongated members being generally parallel to another and lying in a single horizontal plane.
