The invention relates to spectacles, systems and methods for visibility enhancement, including by glare suppression. The spectacles, systems and methods for visibility enhancement includes spectacles and a spectacle lens having a liquid crystal cell (LC), the transmission (TR) of which may be varied by a suitable control and the liquid crystal cell (LC) designed so that the transmission (TR) of the liquid crystal cell (LC) may be switched between high and low transmission states. The liquid crystal cell (LC) includes a control for regulating the times of the state of high transmission (T.sub.on) of the liquid crystal cell (LC) such that the temporal position of the times of the high transmission state (T.sub.on) within a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously; and/or the duration of a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously. Such changes may be determined by a secret coding key.

Light weight ophthalmic lenses include a curved back lens attached to a curved front lens assembly having a functional element. An ophthalmic lens includes a curved front lens assembly and a curved back lens. The curved front lens assembly has an essentially constant thickness, forms an external world-side convex surface of the ophthalmic lens, and includes a functional element operable to modify an image of a real world scene viewed via the ophthalmic lens. The curved back lens forms an external user-side surface of the ophthalmic lens, has a world-side convex surface that is shaped complementary to and interfaced with the front lens assembly, and provides a prescribed vision correction.

Described are eyewear with one or more dimmable vision correction lens stacks. The eyewear can have various form factors, including eyeglasses with a separate lens stack for each eye. The vision correction lens stack may have a first lens and a second lens, with a dimmable liquid crystal layer arranged between the first lens and the second lens. The first lens and second lens may have the same refractive index, the refractive index may be configured according to a prescription of the user. The dimmable liquid crystal layer may be electrically coupled to a control module which may be used to change the light transmittance of the liquid crystal layer.

Eyewear having: an optical module; an input unit; a sensing unit; a storage unit that stores at least conditions that change optical properties of the optical module; and a control unit that performs electric control of the optical module, in accordance with a set mode, by using electric control. The set modes include: a first mode in which the control unit electrically controls the optical module on the basis of a condition stored in the storage unit and a detection value for the sensing unit; and a second mode in which the control unit electrically controls the optical module on the basis of instructions received by the input unit. The conditions stored in the storage unit are updated on the basis of the detection value for the sensing unit when the input unit has received an instruction in the second mode.

Various embodiments of the present invention provide for systems and apparatus directed toward using a contact lens and deflection optics to process display information and non-display information. In one embodiment of the invention, a display panel assembly is provided, comprising: a transparent substrate that permits light to pass through substantially undistorted; a reflector disposed on the transparent substrate; and a display panel aimed toward the reflector and substantially away from a human visual system, wherein the reflector reflects light emitted from the display panel toward the human visual system. The reflector may comprise a narrow band reflector or a polarization reflector.

Embodiments comprise an eyewear having a lens, the lens having an optical filter. A transmittance spectral profile of the optical filter comprises a transmission valley having a minimum transmittance with a spectral bandwidth, wherein the minimum transmittance of the transmittance valley is positioned at a first wavelength from about 450 nm to about 475 nm; and the spectral bandwidth, equal to the full width of the transmittance valley at the minimum transmittance plus 30%, is less than or equal to about 30 nm.
