Is eye mask a tax on intelligence?

A: It depends on whether you buy a "concept" or a "structure". There are three criteria for judgment: ① Whether there is a clear optical structure (such as 1/4λ phase delay layer + magnetron sputtering AR coating), rather than just writing "eye protection" on the packaging; ② Is there any verifiable third-party data (SGS report with a unique number, light transmittance 96.5%, haze 0.4%, report SZIN2606001469PL01_CN)? ③ Can it be verified by oneself? (A circularly polarized light detection card is included with the box. Rotate it to observe the changes in the light state.) If all three are met, it addresses the real optical problems (reflected glare, polarization state of the output light), and is paying for verifiable technology. Be cautious about those who only express feelings without providing numbers or methods.
