Abstract

The invention relates to a test device of lens, and specifically relates to a hand-held blue ray filter out detector and a detection method which are applied for analyzing and testing the blue ray filter out ability. The hand-held blue ray filter out detector consists of a front end of main body, a middle portion of main body, and a rear portion of main body; the front end of main body, the middle portion of main body, and the rear portion of main body form a pistol-like shape; a groove is formed between the front end of main body and the middle portion of main body; a light source generator is arranged inside the front end of main body; a group of photoelectric diodes, a photoelectric signal receiving circuit, a photoelectric signal processing circuit, a control unit and a power supply circuit are installed inside the middle portion of main body; a digital display circuit and a trigger are installed inside the rear portion of main body. The hand-held blue ray filter out detector has the advantages of detachable bracket, calibration-free, battery-powered, small-volume, and 9V battery powered. Therefore, the hand-held blue ray filter out detector can be normally used without an external power supply. The hand-held blue ray filter out detector is characterized in portable.

Description

technical field [0001] The invention relates to a lens testing device, in particular to a hand-held blue light filtering detector and a detection method for analyzing and testing the blue light filtering ability. Background technique [0002] Blue light is a relatively high-energy ray with a wavelength between 400nm and 500nm. Blue light in this wavelength will increase the toxin in the macular area of ​​the eye and seriously threaten the health of our fundus. According to research, a large amount of blue light exists in computer monitors, mobile phones, digital product displays, LED light, and even sunlight. [0003] Blue light has strong energy and can penetrate the lens directly to the retina, causing serious damage to our fundus and macular area of ​​the retina. It is very likely to cause fundus damage after cataract surgery, cause or aggravate diseases in the macular area of ​​the retina, and even lead to blindness in severe cases. Among the 420 million Internet user...
