smart protective glasses

Abstract

The invention discloses a kind of intelligent protective glasses, comprising a frame, mirror legs and photochromic lenses; a controller and a defogging device are arranged in the frame, and the controller is connected to the defogging device; batteries are arranged on the mirror legs, and the batteries are respectively It is connected with the controller and defogging device; the photochromic lens includes a transparent anti-reflection layer, an ultraviolet absorbing layer, a transparent lens, a light absorbing layer, and a photochromic layer in turn; the photochromic layer includes 50% to 75% of polypropylene, 3% ~8% propylene glycol butyl ether, 0.1%~0.3% 1,2-bis[2-methyl-5-(3,4-difluorophenyl)thiophen-3-yl]perfluorocyclopentene, 0.1 ~0.2% WO 3 , 0.3% ~ 0.5% TiO 2 , 0.1% to 0.2% naphthopyran, and the balance is polyethylene. The photochromic lens of the present invention can not only realize photochromic change, but also can absorb ultraviolet rays and other harmful light rays, and can also automatically change color according to light intensity, effectively avoiding damage to eyes caused by long-term use of computer and mobile phones.

Description

technical field

[0001] The invention relates to the field of glasses, in particular to smart protective glasses. Background technique

[0002] Today, with the rapid development of science and technology, high-tech equipment such as mobile phones and computers are used more and more widely, and become indispensable in daily work and life. This type of equipment has strong functions, such as analyzing data, scientific computing, graphic design, etc., or in the field of spacecraft manufacturing, this type of equipment can also play a greater role.

[0003] However, the regular use of this type of equipment is more harmful to our eyes. First, strong light and reflected light can cause eye fatigue, myopia, astigmatism, etc. The second is positively charged ions, which affect the central nervous system, destroy red blood cells, and damage hematopoietic function. The third is low-frequency radiation, which is the most serious but also the least noticeable type of damage. It is a...
