This application relates to a corrective lens and diopter adjustment method for AR glasses displays, belonging to the field of AR displays. It is used for mounting on AR glasses. The waveguide glasses include a frame and a waveguide lens, including a central beam. A polarizer assembly and a correction assembly are connected to the inner and outer sides of the central beam via clamps. The polarizer assembly and the correction assembly are clamped to the inner and outer sides of the frame via clamps. The correction assembly includes a light-transmitting base and an adjustment component. The light-transmitting base is hollow and contains a liquid light-guiding medium. A planar transparent substrate is located on one side of the light-transmitting base near the waveguide lens, and a transparent elastic layer is located on the other side. The planar transparent substrate, the liquid light-guiding medium, and the transparent elastic layer are stacked together to form a diopter lens with diopter. The adjustment component is configured to adjust the liquid pressure of the liquid light-guiding medium. The pressure difference between the liquid light-guiding medium and the external atmosphere causes deformation of the transparent elastic layer, thereby changing the thickness and surface curvature of the diopter lens.

This application discloses a near-eye display device and a near-eye display apparatus. The device includes an eye-tracking system, an optical display system, and a corrective lens. The eye-tracking system includes a light source module and an image acquisition module. The light source module emits polarized light. The image acquisition module includes a stray light suppression component, which can suppress at least a portion of stray light from entering the image acquisition module. The stray light is polarized light reflected by the corrective lens. The polarization properties of the light transmitted through the stray light suppression component are different from the polarization properties of the stray light reaching the image acquisition module. This avoids stray light formed after the illumination beam is reflected by the corrective lens from entering the image acquisition module, which helps improve image clarity and thus improves the accuracy of eye-tracking calculations.

A unitary lens structure is provided which is employable with spectacles as well as goggles and safety eyewear and AR and VR eyewear. The lens is formed as a unitary structure with a curved first lens having one or a plurality of projections thereon having surfaces which are formable to prescription eyewear providing vertical vision correction and curved horizontal vision correction.

A custom lens device is disclosed as a corrective lens created by a specialized 3D printer. Specifically, a qualified technician working with an ophthalmologist and / or an optometrist combine laboratory measurements of the retina and other eye surfaces, then combine that data with subjective input from the patient's correction to an Amsler grid, to create a custom lens that will un-distort vision which has been distorted (i.e., warped), due to undulations in the retina caused by a number of eye diseases, including, but not limited to, epiretinal membrane and macular degeneration.

This invention discloses a corrective lens belonging to the field of lens technology, comprising: a first region, a second region, a third region, a fourth region, a fifth region, a sixth region, a seventh region, an eighth region, and a ninth region; the first region is the central area, composed of a basic spherical lens and a cylindrical lens, used for precise refractive correction; the lens adopts a nine-square grid layout, which prevents reversal naturally and has a significant effect on myopia correction.
