The best-studied lens is dark all day.

Around 3% of people with epilepsy are photosensitive, and it most often starts between ages 7 and 19.1

Tinted lenses have strong evidence. In a study of 610 patients, the Zeiss Z1 lens abolished the light-triggered EEG response in 75.9%.2 But the Z1 lets through only about 7% of light,3 so occasional protection costs dim vision every waking hour.

Lensare starts from a different idea: light by default, dark only while light is harsh.

How Lensare works

Flash-checked. No flashing lights are shown on screen, and this video passes the WCAG 2.3.1 flash test for photosensitive viewers.

Real footage of V3 prototypes

  1. Light by defaultMost of the time, they're just glasses with a lighter everyday tint.

  2. Watching the lightSensors in the frame watch the light around you, and firmware looks for bright or flickering light.

  3. Dark when light turns harshIn bench tests, the lenses darken in about 20 milliseconds, then clear when the light settles.

Lensare V3 in numbers

Light enough to live in

36% light transmission most of the time: sunglass category 2.

Dark only when triggered

Down to 0.3% in about 20 milliseconds, while harsh light lasts. Then it clears.

Full-day battery

21 hours of intensive use, with USB-C charging.

Low profile and light

55 grams, with arms just 8.5 mm thick.

Lensare's tint range

Light transmission is how much light gets through a lens. Clear glasses let almost all of it through. Lensare works between 36% and 0.3%.

36%Everyday tint. How the glasses sit most of the time.

0.3%Full tint. Only while harsh or flashing light lasts.

When harsh or flashing light hits, the lenses switch from 36% to 0.3% (in about 20 ms in bench tests), then clear again once it passes. Lensare isn't for driving or cycling.

What we can and can't say yet

Lensare hasn't been clinically tested. We won't claim it reduces seizures or migraine symptoms until a study shows it does. It's being developed to sit alongside medical care, not to replace it.
