  • Anti-blue light glasses

    • All LED screens, whether smartphones, tablets, computer screens or televisions, emit blue light, which is particularly harmful to the eyes.
    • Mastuvue lenses filter 40% of this blue light, which helps reduce eye fatigue, eye irritation and headaches. This filtering is made possible by a specific treatment that gives the lenses a slight yellow tint, while ensuring that the perceived colors are respected. Enjoy your screens with complete peace of mind!

    • Information :
      We spend an average of more than 50 hours a week in front of screens such as smartphones, computers, televisions, or video games. However, all these LED backlit devices emit blue light. Thanks to a specific revo treatment, our glasses filter part of the blue-violet light, while allowing the passage of blue-turquoise light, essential to our well-being.

  • Sun protection glasses

    • The sun emits electromagnetic waves, both visible and invisible. Among the invisible radiations, the most dangerous are ultraviolet (UV) rays, which can damage the cells of the eye and cause various pathologies, even on cloudy days, because clouds only filter about 10% of them.
    • MASTUVE sun lenses are category 3 and offer UV400 protection, which means they block 100% of UV rays, including UVA and UVB, up to a wavelength of 400 nanometers. This complete protection not only prevents glare, but also effectively protects your eyes from the harmful effects of ultraviolet rays, reducing the risk of developing long-term eye problems.
