Your questions answered

  • Night Shift only adjusts your screen. It doesn't touch the LED ceiling light above you, the lamp next to the couch, or the TV across the room. After sunset, blue light comes from everywhere — not just your phone. HEVO filters everything that reaches your eyes, not just one screen.
  • Most blue light glasses use clear lenses that filter a small fraction of what matters. HEVO's Sleep Lens blocks 99% of the wavelengths that suppress melatonin — the ones between 400 and 550nm. It's a completely different category of lens. You'll see it the moment you put them on.
  • the tint shifts colors. That's how you know it's actually working — if the lens looks clear, it isn't blocking much. Most people adjust within a few minutes and stop noticing. You're wearing these for the last 1-2 hours of your evening, not all day.
  • You can. Two hours of no screens, plus dimming all the lights in your home, would have a similar effect. But most people aren't going to do that. HEVO lets you keep your evening — read, watch something, scroll — without the biological cost. It's the realistic version of "just avoid screens.
  • Each lens is designed for a different part of your day. Sleep Lens for the evening — blocks 99% and signals your body to wind down. Focus Lens for screen-heavy days — takes the edge off without changing how you see. Relax Lens for the hours in between. Most people start with Sleep and go from there.
