help Zoff PC FAQ
Can I get Zoff PC glasses with my prescription lenses?
Yes, Zoff offers their blue-light-blocking PC coating on prescription lenses, including single-vision and progressive options. You can select your lens type and add the PC coating during the ordering process at Zoff retail stores in Japan or through their website.
How much blue light do Zoff PC lenses actually block compared to other brands?
Zoff PC lenses are designed to reduce blue light in the 380–500nm wavelength range emitted by digital screens. Zoff does not publicly specify an exact percentage blocked, but the coating is comparable to other mass-market blue-light glasses like those from JINS PC rather than premium prescription-grade lens coatings from Zeiss or Hoya.
Can I add Zoff PC blue-light coating to non-prescription glasses?
Yes, Zoff offers PC blue-light-filtering lenses with no prescription (plano) for users who want screen protection without vision correction. This is popular among contact lens wearers who still want eye protection at their desk during extended computer use.
