Abstract: The present invention provides a screening method for searching a component inhibiting or treating scleral thinning, and eyedrops that contain the active ingredient, and hence can inhibit excessive thinning of the sclera, and as a result, can treat a posterior segment eye disease associated with the scleral thinning. The problems are solved by eyedrops containing, as an active ingredient, a component capable of simultaneously inhibiting the PERK pathway and/or the ATF6 pathway. The problems are solved by a screening method for a component capable of simultaneously inhibiting the PERK pathway and/or the ATF6 pathway, including a step of contacting a candidate substance with an eye-derived cell, and a step of selecting the candidate substance using, as an indicator, influence on scleral thinning in the cell.

Abstract: The ophthalmic composition effective for the prevention or treatment of myopia or ocular diseases are provided. In particular, the present invention provides an ophthalmic composition effective in a growing child or a young person in whom myopia develops and progresses, as well as a middle-aged and elderly person in whom age-related ocular diseases such as cataract, glaucoma, retinal detachment, retinopathy, maculopathy, choroidal neovascularization, posterior staphyloma, and optic neuropathy develop, a functional food containing the ophthalmic composition, and a screening method capable of searching for the same. [Solution] The above problem is solved by an ophthalmic composition or functional food product containing at least one component selected from the group consisting of crocetin and its pharmaceutically acceptable salts and ginkgo leaf extract.

Abstract: The purpose of the present invention is to provide a myopia prevention device. A myopia prevention device of the present invention comprises a light transmission part selected from a group consisting of an eyesight correcting tool, an eye protection tool, a face protection tool, a sunshade, a display device, a window, a wall, a light source covering, and a coating material. The light transmission part of the device transmits light having a wavelength within a range of 350 nm to 400 nm inclusive and thus suppresses the occurrence and progression of myopia. Further, a myopia prevention device comprises a light emission part selected from a group consisting of lighting equipment, a display device, and a light irradiation device. The light emission part of the device emits light having a wavelength within a range of 350 nm to 400 nm inclusive and thus suppresses the occurrence and progression of myopia.

Abstract: The present invention provides a screening method for searching a component inhibiting the PERK pathway and/or the ATF6 pathway, and by obtaining, by the screening method, an active ingredient inhibiting myopia progression without impairing normal growth of the eyeballs (emmetropization) in children, provides eyedrops and a composition containing the active ingredient. The problems are solved by eyedrops for inhibiting myopia progression in children containing, as an active ingredient, an inhibitor of the PERK (PKR-like endoplasmic reticulum kinase) pathway and/or the ATF6 (activating transcription factor 6) pathway. The problems are solved by a screening method for an inhibitor of myopia progression in children, including a step of contacting a candidate substance with an eye-derived cell, and a step of selecting the candidate substance using, as an index, change in a protein and/or a gene of the signal transduction system of PERK and/or ATF6.

Abstract: To provide a display system such as a smartphone, a game console, a personal computer, or a liquid crystal television, including a light-emitting element that irradiates light having a specific wavelength toward a user. The above-described problem is solved by a display system (1) including a first light-emitting element (6) that emits light used for image display, a second light-emitting element (3) that irradiates light (7) within a wavelength range of 360 nm to 400 nm, inclusive, toward a user, and a control unit (10) that controls irradiation of the light (7) from the second light-emitting element (3).At this time, the second light-emitting element (3) may be a single light-emitting element integrated with the first light-emitting element (6) or a light-emitting element provided separately from the first light-emitting element (6). When separately provided from the first light-emitting element (6), the second light-emitting element (3) is preferably provided to a peripheral frame (4) of a display screen (2), in the display screen (2), or as an accessory (5).
