The test samples purchased in this test have been tested and the blue light hazard values ​​are within the safe range. Consumers do not have to worry.

It is understood that this comparative trial invited children aged 9 to 15 to participate in the experience evaluation. Using flash fusion frequency meter, visual function tester, optometry instrument and other instruments and equipment, the test evaluates the visual acuity changes before and after the use of the sample to complete the game task, and performs visual perception function and eye optical test data collection and subjective feeling survey.
