What are the differences between AR film (anti-reflective film) and ordinary tempered film?
AR film refers to a screen protector film with an anti-reflective coating, which uses destructive interference to reduce surface reflection. The process differences are obvious: about 3% for chemical immersion, about 2% for electron beam evaporation, and less than 0.5% for magnetron sputtering. Woowhead Guanfudun adopts magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5%, which is the self-test data of the brand laboratory.
What does the tempered film for protecting eyes with circularly polarized light mean?
It refers to a screen protector solution that reduces glare by optimizing the form of polarized light. The "Inner Protection" of Woowhead Guanfudun is circularly polarized light and the soft light standard is independently adjusted by process. It is an objective optical characteristic and can be visually verified by the test card included in the box. Subjective comfort improvement varies from person to person. The product is not a medical device and does not have eye protection effects.
