Measuring device and method for retina safety improvement index

Abstract

The invention mainly discloses a measuring device and method for a retina safety improvement index. The device mainly comprises a light receiving unit, a first processing unit and a second processing unit, and during normal operation, the light receiving unit receives a visible light and a treated visible light subjected to blue light resistance treatment by an anti-blue light unit. On the other hand, the first processing unit is used for calculating allowable exposure time of the visible light and the treated visible light, and then the second processing unit can further calculate a retina safety improvement index corresponding to the anti-blue light unit. Through the design, a general consumer only needs to measure the retina safety improvement index of any anti-blue-light product sold in the market by using the measuring device for the retina safety improvement index disclosed by the invention, so that eye protection effects of the anti-blue-light product can be known on the basis without watching a strange spectrogram and without understanding the meaning represented by the blue light filtering percentage value.

Description

technical field [0001] The present invention relates to the related technical field of eye protection index calculation, in particular to a measuring device and method for retinal safety improvement index. Background technique [0002] It is known that natural light is divided into visible light and invisible light, of which infrared light and ultraviolet light belong to invisible light, and red, orange, yellow, green, blue, indigo, and violet light belong to visible light. The retina is an important part of the human eye, which is used to convert light signals into neural signals. It should be known that sunlight is natural light with a continuous spectrum and includes the entire visible light range, figure 1 That is, the spectrum of sunlight is displayed. White LEDs are currently the mainstream artificial light-emitting components, and have been widely used in various lamps, backlight modules, and self-illuminating display panels. figure 2 That is, a spectrogram of a w...

Problems solved by technology

[0005] It is a pity that the aforementioned percentage values ​​and spectrograms can only be used to express or confirm the blue light blocking ability of commercially available anti-blue light lenses or anti-blue light eye protection patches, and ordinary consumers cannot know these anti-blue light solutions through these data How much safety protection effect can it bring to its eyes, not to mention the authenticity of the blue light blocking ability advertised by commercially available anti-blue light lenses or anti-blue light eye protection patches is also open to question

[0006] From the above description, it can be seen that there is still a lack of an indicator used to indicate the eye safety protection effect of any anti-blue light solution, so that users (consumers) can accurately know the anti-blue light they choose based on this indicator. How much eye protection effect can the program have?
