Super Blue Light Cut Glasses are PC glasses equipped with the latest lenses that cut 94% of blue light (HEV400-420nm). They cut approximately 94% of blue light (HEV400-420nm) emitted from computers, smartphones, TVs, tablets, and other devices. Using a new standard of ultraviolet absorbers, these glasses far surpass the performance of conventional blue light cut coatings. Their performance has been tested and certified by the Japan Spectacles and Popular Optics Inspection Association, a third-party organization specializing in eyeglasses and popular optical instruments, located in Sabae City, Fukui Prefecture, the mecca of eyeglasses. They prevent damage to lutein, which can cause eye diseases, and reduce oxidative stress. You can expect to maintain eye health as easily as taking supplements. In addition to blue light, they also protect your eyes from ultraviolet rays. With 99.9% UV protection, they can also be used as clear sunglasses. These are high-performance glasses that are gentle on the eyes. The frames feature an asymmetrical front design with round and square shapes. They are unique and stylish frames. Unlike mass-produced products, we (in Japan) process each pair individually. As an optician with many years of experience, we strive to satisfy our customers with our accumulated techniques. 【Lens Width】39mm 【Nose Width】27mm 【Temple】136mm 【Vertical Width】36mm 【Frame Width】130mm
