Problems solved by technology

[0003] In 2000, "Family Medicine" Shangdang Qun and others published an article titled "Vision Fatigue Before VDT", which showed the damage of computers, TVs and electronic luminous screens to human eyes: long-term exposure to electronic luminescence at close range The product is likely to cause VDT (Video Display Terminal Syndrome) syndrome, which is 4 to 6 times more visually fatigued than paper work, and causes a significant decline in the eye's visual adjustment function, less tear secretion and poor quality, and the tear film breaking time is significantly shortened , resulting in dry eyes; corneal pigmentation rate increased from 3.2% to 60.8%, decreased eye resistance, easy to infection
If teenagers wear goggles with yellow lenses for a long time, it will have adverse effects on the development of cone cells, resulting in color weakness or even color blindness.
[0007] In addition, the light transmittance of the yellow lenses in the prior art is generally low, and the light transmittance is all below 70% in the visible light wavelength distribution range (390-760nm).

Abstract

The invention provides a light green goggle lens for prevention of an electronic luminescent screen hurts. The lens is composed of a substrate and an evaporation coating film layer, wherein the substrate contains a short-wave visible light absorbing agent and is made of organic high-molecular polymers containing an ultraviolet absorbing agent. The lens can almost completely absorb ultraviolet rays and high-energy purple and blue visible light which are emitted by the electronic luminescent screen, hurts of ultraviolet rays and short-wavelength photons to retinas are avoided, simultaneously, almost no color difference exists, and the lens has the low color temperature, so that eyes are in the environment close to the nature, the normal growth and development of retina photosensory cells are not influenced and hurt, and the lens is applicable to growing youngsters.

Description

technical field [0001] The present invention relates to a kind of lens and a kind of spectacles made of the lens, more specifically, the present invention relates to a kind of protective lens and spectacles specially used for juveniles to prevent electronic luminescent screen. Background technique [0002] With the widespread use of electronic products, especially portable electronic products such as smartphones and ipads are used by more and more teenagers, the myopia rate of teenagers has risen sharply, and it is easy to cause vision problems such as anisometropia and even strabismus. [0003] In 2000, "Family Medicine" Shangdang Qun and others published an article titled "Vision Fatigue Before VDT", which showed the damage of computers, TVs and electronic luminous screens to human eyes: long-term exposure to electronic luminescence at close range The product is likely to cause VDT (Video Display Terminal Syndrome) syndrome, which is 4 to 6 times more visually fatigued tha...
