Problems solved by technology

[0005] However, polyvinyl alcohol-based polarizers are thin sheets with weak physical strength and lack of moisture resistance. Therefore, it is difficult to form lenses with only polarizers, and it is considered difficult to use them as anti-glare glasses with high practicality.

Embodiment 1

[0102] figure 1 The single-eye polarized glasses according to the present invention are shown.

[0103] figure 2 A lens of the above polarized glasses is shown. The area indicated by the oblique lines on the lens is the polarizer part. As shown in the figure, the polarizing element is separated into a right-eye lens and a left-eye lens.

[0104] Both sides of each polarizing element are protected by a protective sheet to form independent polarizing plates. The polarizing elements are each bent into a toric shape, and the supporting resin is thermally bonded to the protective sheet on the concave side of the bent polarizing plate. Integrate to form a 1-mesh polarized lens.

[0105] The thermal bonding method is a method of inserting a bent polarizing plate into a mold and injecting a supporting resin.

[0106] In this embodiment, the protective sheets on both sides of the polarizing element with a thickness of about 30 μm are polycarbonate with a thickness of about 400 μm...

Abstract

An object of the present invention is to provide single-lens type polarizing glasses which are optically sufficient in performance, and are rich in variety from a view point of design. Both of a polarizer of a right eye lens and a polarizer of a left eye lens can be two independent polarizing plates, both sides of which are protected with protective sheets, respective polarizing plates are bending-processed into a spherical, nonspherical or toric shape, and a backup resin is thermally adhered on the protective sheet on a concave side of the bending-processed polarizing plate to make a single-lens type polarizing lens, which is further prepared into single-lens type polarizing glasses.

Description

【Technical field】 [0001] The present invention relates to single-eye polarized glasses in which a polarizing element is separated into a right-eye lens and a left-eye lens. [0002] The 1-mesh polarized glasses are not only used as eye protection, but also because the curved surface can be freely designed for each lens, so the 1-mesh polarized lens can be made with the same curved surface design idea as that of the 2-mesh polarized lens. It is used as polarized glasses with less visual distortion in daily life or sports, and as sunglasses for outdoor sports. 【Background technique】 [0003] As an anti-glare measure to reduce reflected light from the water surface, polarized glasses with built-in polarized lenses have been used for a long time. [0004] The polarizing performance of a polarizing lens depends on the polarizing element. The polarizing element is generally a polyvinyl alcohol stretched sheet with a thickness of 100 μm or less, and the sheet is dyed with iodine ...
