POLYMERIZABLE COMPOSITION FOR OPTICAL ARTICLE AND OPTICAL ARTICLE
Provided is a polymerizable composition for an optical article, said composition including component A and component B below. Component A: A polyfunctional (meth)acrylate having a molecular weight of 500 or more and containing a polyalkylene glycol moiety. Component B: A monofunctional (meth)acrylate represented by formula 1. Component C: A photochromic compound. (In formula 1, R10represents a hydrogen atom or a methyl group, and R11 represents a straight chain alkyl group with three or more carbon atoms or a branched alkyl group with three or more carbon atoms.)
A spectacle lens comprising a base material and an antifogging layer, wherein the thickness of the antifogging layer is 5-50 μm, and the antifogging layer contains a resin and an antimicrobial agent.
A refraction characteristics measuring device (1) measures the refraction characteristics of an eye (25), and comprises: a light emitting unit (20); an aperture member (10) that is positioned between the light emitting unit and the eye and includes a first aperture (11) and a second aperture (12) that stop down, and allow the passage of, the light emitted from the light emitting unit; a first optical element (13) that is provided in the first aperture and is transmissive to light of a first wavelength band; and a second optical element (14) that is provided in the second aperture and is transmissive to light of a second wavelength band. The light emitting unit comprises a background unit (23) that emits white light, a first optotype unit (21) that emits first light (L1) of a complimentary color to the light of the first wavelength band, and a second optotype unit (22) that emits second light (L2) of a complimentary color to the light of the second wavelength band.

Provided is a spectacle lens comprising a functional region having: a base region that causes a luminous flux having entered from the surface on the object side to be emitted from the surface on the eyeball side, to enter the pupil of a wearer, and to be converged on the retina; and an epiretinal non-convergent region that causes the luminous flux having entered from the surface on the object side to be emitted from the surface of the eyeball side and does not cause the luminous flux having entered the pupil of the wearer to be converged on the retina. At least a part of the epiretinal non-convergent region is a buffer region in which a local negative astigmatism generated by the spherical aberration of the eye can be offset at a partial portion of the distribution of the astigmatism, and every surface shape of the buffer region is a toric surface having an axial direction in the circumferential direction and is a long shape along the circumferential direction in a plan view. Also provided is a technology pertaining to the spectacle lens.
Provided is a lens frame for eye examination with which eye examination can be performed in a suitable condition, even in a condition other than a horizontal view such as a downward view. A lens frame (1) comprises: a lens holding member (20) that has a pair of lens frames (220) for respectively holding lenses; and a pair of temple members (10). The temple members (10) each comprise a front temple part (32) which supports the lens holding member (20), a rear temple part (34) which is connected to the rear of the front temple part (32), and an angle-adjustable connection part (36) by which the angle of the front temple part (32) to the rear temple part (34) is adjustable around a pivot center part thereof. The front temple parts (32) each have a length adjustment mechanism (324) for adjusting the length of the front temple part (32).
The present invention provides a photochromic compound expressed by general formula 1. In general formula 1, R represents an unsubstituted aliphatic monocycle having at most six carbon atoms (including the carbon atom at position 13 of the indeno-fused naphthopyran), and R1-R8, B, and B' each independently represent a hydrogen atom or a substituent group, with the caveat that at least one of R1-R8 represents an electron-withdrawing group.
