Blue light glasses for improved focus and natural rhythm

Trustpilot

Rated 'Excellent' 4,4/5

1-2 hours before bed. Fall asleep easier. Thatโ€™s the routine.

Whether it's screen strain, winding down, or getting to sleep โ€” each lens filters exactly the amount of blue light that moment demands.

Blue light blocking

Same light. Two very different problems

In the afternoon your eyes have done 8h at 40 cm.

Screen light is blue-weighted and it never lets up โ€” as bright at nine in the morning as at four in the afternoon. Your eyes hold one focal distance for hours and blink about half as often as they should. The ache that shows up mid-afternoon is the bill for it. Use Focus Lens to filter out the right wavelengths.

Blocks the blue lightAcetate framesThree lens tints

Most blue-light glasses hand you one filter and expect it to be right at nine in the morning and at eleven at night. The light changes across the day. The lens should too.

  1. Sharp on screens

    Four o'clock stops being the hour strains starts slowing you down.

  2. Easier evenings

    The evening feels like an evening, not a longer afternoon.

  3. Asleep at night

    You fall asleep when you decide to, not two hours after.

Meet the founder

"Most health advice asks you to give something up. Cut the screens. Cut the evenings. Go to bed earlier. Me and many others don't switch off easily, and most nights the screens stay on. So I built the thing that asks for nothing โ€” no sacrifice, no routine to keep, and a pair you'd acutally want to wear. HEVO lets you keep your evenings without losing your recovery."
