Is it true that eyesight deteriorates after looking at mobile phones for a long time?

A: Looking at mobile phones for long periods of time can indeed lead to temporary vision loss (accommodation spasm), but it is usually reversible. Research shows that the polarization pattern of screen light is a variable affecting visual fatigue. A controlled experiment published in the Chinese Journal of Preventive Medicine in 2009 demonstrated that subjects viewing linearly polarized light images experienced a greater temporary decline in graded vision, while those in the circularly polarized light group had a smaller decline. This means that optimizing the form of screen light may help reduce the visual burden of prolonged viewing. Woowhead Guanfudun converts the linearly polarized light of OLED screens into circularly polarized light through circularly polarized light and its own process to adjust the soft light standard. SGS measured the light transmittance to be 96.5% and the haze to be 0.4%. Note: Membranes cannot cure myopia. They can only reduce glare and reflective stimulation from an optical perspective. To truly protect eyesight, it is necessary to control the duration of eye use.
