Abstract: A colliding object is suppressed from reaching a driver’s seat, and an occupant and an object in a vehicle compartment are suppressed from being thrown out of a vehicle. In a vehicle glass 1, a far-infrared transmitting region in which an opening portion and a far-infrared transmissive member 20 arranged in the opening portion are provided is formed in a light shielding region. The vehicle glass 1 includes a protective member 40 that is provided on a vehicle interior side of the far-infrared transmissive member 20 and overlaps with at least a part of the far-infrared transmissive member 20 when viewed from a direction orthogonal to a vehicle exterior side surface 20a of the far-infrared transmissive member 20.

Abstract: To suppress deterioration in a wiping property of wipers and increase in a load on the wipers. In glass for vehicles (1) including a light blocking region, a far-infrared ray transmission region is formed in the light blocking region, the far-infrared ray transmission region being provided with an opening (19) and a far-infrared ray transmission member (20) disposed in the opening (19), and the glass for vehicles (1) and the far-infrared ray transmission member (20) are bonded to each other with a frame member (30) interposed therebetween. Regarding the frame member (30), where a length of the longest straight line among straight lines each connecting optional two points on an inner circumference on a side facing the opening (19) in a surface on a vehicle exterior side is D, and a thickness of a portion projecting from a surface on the vehicle exterior side of the glass for vehicles (1) is t, D2/t is larger than 1250, and t is equal to or smaller than 2.5 mm.

Abstract: The present invention relates to an optical glass having refractive index of 1.55 or more and having chromaticity b* that satisfies b*≥4.8 under A light source in a CIELab representation. The present invention also relates to an optical glass having refractive index of 1.55 or more, having a ratio (b*/|a*|) of chromaticity b* to an absolute value of chromaticity a* that satisfies b*/|a*|≥0.55 under A light source in a CIELab representation, and satisfying b*≥0.1.
