Abstract

The invention relates to a blue light tester used for testing a lens. The blue light tester comprises a light source producing device, a blue light filtering detector, an amplifier, a driver and a digital display, wherein the light source producing device is used for producing a light source irradiating the lens, the blue light filtering detector is used for detecting the intensity of blue light in the light source passing through the lens and transmitting a detected intensity signal of the blue light to the amplifier, the amplifier amplifies the intensity signal of the blue light and transmits the intensity signal to the driver, the driver is connected with the digital display, and the digital display displays a numerical value of the lens with the blue light filtered. The blue light tester has the advantages of being low in cost and high in speed, resisting to the blue light, and displaying instantly, and a consumer can watch conveniently in time.

Description

technical field [0001] The invention relates to a device for testing lenses, in particular to a blue light tester for testing the attenuation degree of blue light. Background technique [0002] At present, LEDs are mostly used as light sources in the market. This light source has the advantage of low power consumption. It is applied to various electronic products, such as various digital displays using LEDs as backlights. A large amount of intense blue light is emitted, and the characteristic of blue light is that it is very easy to scatter, and the scatter is the cause of blurred images and eyestrain. [0003] Due to the above-mentioned effects of blue light on the human eye, there are currently manufacturers producing glasses that filter out blue light. Various digital monitors can see clear images and reduce eye fatigue. But now there are a lot of glasses that filter out blue light on the market, and some products can't achieve the above effects. Therefore, if there is...
