LENS DATA
Lens transmission, measured
Compare the published NoBlue Day and Evening lens measurements below. These figures describe optical performance and do not guarantee a specific health outcome. Source details are shown alongside the measurement summary when available.
Lens performance at a glance
| Lens system | Primary use | Visible tint | Blue light blocked, 400–500 nm |
|---|---|---|---|
| Day | Daytime screen routines | Light yellow | 40% |
| Evening / Orange | Artificial light and screens after dark | Orange | 100% |
Published NoBlue spectral transmission measurements. Optical filtering measurements describe lens transmission and should not be interpreted as a guaranteed clinical outcome.
Use the measurements, then choose by use case
The best starting point is not a universal percentage. It is the combination of lens transmission, visible tint and the time of day you plan to wear the glasses.
