How do you take care of
your break
The red R2251 lens blocks 99.7% of blue-violet light—the spectrum that suppresses melatonin and disrupts the biological clock. By only allowing warm red light to pass through, your brain receives the correct signal to prepare for sleep.
01
Protects melatonin production
TSB 0.27% in the 380–500nm band. Blocks 99.7% of blue-violet light — the main inhibitor of melatonin. Wearing these glasses 1–2 hours before bed helps the brain initiate its natural sleep cycle.
02
Warm light for rest
It allows for the exclusive passage of the red and warm spectrum (600–780nm), the only range that does not interfere with the circadian clock.
03
Ideal for nighttime displays
TV 22.03% — reduced transmission that minimizes the impact of LED light from monitors, cell phones, and televisions at night.
04
Reduction of night eye strain
By eliminating blue-violet light from artificial light sources, eye strain in low-light conditions is reduced.
