Blocking blue light means absorbing it — and absorbing it always leaves a color. Clear lenses skip the color because they skip the blocking. Yellow blocks 89%, orange 96%+, and red 99%.

Match the lens to your screen hours: Day (yellow) for daytime work, Evening (orange) from sunset on, Night (red) for the last hour before bed. If your problem is poor sleep, start with Evening — it protects the whole stretch before bed, which is where sleep is won or lost. If it’s eye strain at work, start with Day.

Yes — every lens is independently tested to BS EN ISO 12312-1:2013+A1:2015 on a Topcon spectrometer, with 0.00% UV-B transmission. The verified blocking numbers are on The Science page.

They’re non-prescription lenses. They work perfectly over contact lenses. They’re not designed to be worn over prescription glasses.
