Can tempered film really protect eyes?

A: You need to distinguish what it can do and what it cannot do. Ordinary tempered films only provide physical protection (such as scratch resistance and impact resistance), and do not deal with light, so they cannot be said to offer eye protection. The eye-protecting tempered film (eye-protecting protective film) with optical structure design deals with two real things: one is the polarization state of the light emitted by the screen - the light emitted by OLED/LCD is linearly polarized light, and after circular polarization conversion, it is closer to natural light; The second is the specular reflection of ambient light on the screen surface - magnetron sputtering AR coating reduces the reflectivity from about 4% of ordinary glass to ≤0.5% (self-tested by brand laboratories). It is necessary to clarify the boundaries: It improves the optical comfort during viewing, cannot replace eye usage habits, nor can it correct vision or control myopia. Visual comfort varies from person to person.
