Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] Such as figure 1 As shown in (a) to (c), a kind of anti-blue light glasses with high transmittance is composed of a frame 1, two lens bodies 2 fixed on the frame 1, and two mirror feet 3, which are respectively arranged on two A multilayer film stack 4 and a multilayer film stack 5 are formed on both sides of a lens body 2, wherein the multilayer film stack 4 is deposited on the fronts of the two lens bodies 2 (we define the side away from the human eye as the front side), and more The layer film stack 5 is deposited on the back of the two lens bodies 2, and the two lenses can be plano lenses, short-sighted lenses or long-sighted lenses.

[0052] In the present invention, the optical characteristics realized by the special film system on the two lenses are obviously different from the general anti-blue light lens without the film system. At present, ...

Abstract

The invention discloses a high-transmittance anti blue-ray lens, eyeglasses and device, and a manufacturing method thereof. The front face of a lens body is deposited with a full-medium multilayer film stack with the characteristic of a selective transmission attenuation band, and a back face is deposited with a wide-wave-band anti-reflection multilayer film stack at a visible light band; the high-transmittance anti blue-ray lens needs to meet the conditions: the transmittance at the wave band of 420 nm-450 nm is less than or equal to 80%, the transmittance at the wave band of 465 nm-700 nm ismore than or equal to 90%, and the transmittance at the wave band of 300 nm-380 nm is less than or equal to 1%. Through selection of the appropriate high and low refractive index film layer design, the attenuation transmission is achieved in a specific high-energy blue ray wave band, and high transmittance is achieved in the rest of wave bands, so the anti-blue protection with basic color balanceis achieved. The lens has the advantages of compact structure, simple manufacturing process and low cost, and is convenient for large-scale production.

Description

technical field [0001] The invention relates to a living device, in particular to an anti-blue light lens, glasses, equipment and a manufacturing method thereof, which can be applied to fields such as display and life medicine. Background technique [0002] At present, the display screen or lighting system on the market is often realized by white LED, because the LED light source has the advantages of low-voltage power supply, low energy consumption, strong applicability, high stability, short response time, no pollution to the environment, and multi-color light emission. At present, the most common way to prepare white LEDs is to use gallium nitride blue LEDs plus YAG phosphors. The radiation spectral intensity of gallium nitride blue LED is mainly concentrated in the range of 400-500nm, and the peak radiation intensity is limited around 415-455nm. The radiation spectral intensity of this white light LED has strong radiation intensity in blue light, especially in the low-e...
