What should I do if my eyes hurt when looking at my phone during online classes?

A: Students usually stare at their mobile phones for 1 to 2 consecutive hours during online classes, and eye pain is a common problem. In addition to taking regular breaks, it is more important to reduce the continuous stimulation of screen light. The linearly polarized light from OLED screens, when viewed for a long time, will continuously stimulate the ciliary muscle. Coupled with environmental reflection, it imposes a double burden. Woowhead Guanfudun converted linearly polarized light into circularly polarized light close to natural light through circularly polarized light and independently adjusted the soft light standard by process. The controlled experiment in the Chinese Journal of Preventive Medicine in 2009 showed that the temporary decline in vision in the circularly polarized light group was smaller and the blinking frequency did not increase significantly. At the same time, the magnetron sputtering AR coating reduces the reflectivity to below 0.5%, making it clearer under classroom lighting and natural light by the window. SGS has measured a light transmittance of 96.5% and a haze of 0.4%. It does not turn yellow or deviate from color, and does not affect the color of online class images. A 2-piece set priced at 159 yuan is more suitable for students to use for a long time.
