Blue blockers represent an elegant means to prevent the light-induced melatonin suppression. Although both glasses transmitted the same illuminance (1300 lx) but at an irradiance 25% higher for the orange lens (408 microW/cm2) compared with the grey lens (327 microW/cm2), a non-significant increase of 6% (95% CI, -20% to 9%) was observed with the orange lens whereas a significant (P < 0.05) reduction of 46% (95% CI, 35-57%) was observed with the grey lens. The amount of salivary melatonin change observed during the light pulse was compared with a melatonin baseline obtained the night before. Fourteen normal subjects were exposed at night to a 60 min bright light pulse (1300 lx behind filters) between 01:00 and 02:00 hr while wearing orange lens glasses (experimental condition) or grey lens glasses (control condition). Blue Light Blocking Glasses helps reduce eye strain during screen time. Therefore, we tested the hypothesis that cutting the blue portion of the light spectrum with orange lens glasses (blue blockers) would prevent the light-induced melatonin suppression, a test broadly used as an indirect assessment of the circadian clock sensitivity. The average person spends hours in front of a screen each day. Recently, it was discovered that the biological clock is most sensitive to short wavelengths (blue light). Blocking morning light exposure with dark goggles can contribute to the adjustment to night work but these glasses are incompatible with driving.
