  • TV screens and computer monitors both emit a great deal of blue light, and sitting in front of either in the hour before going to bed is one of the worst things we can do for our sleep pattern, since it confuses the brain (our brain is getting ready for night-time yet is receiving this signal to suppress melatonin and be alert).
  • The high-quality lenses do not distort colors and in fact, sharpen the clarity of both images and text.
• Lenses are high-quality stylish wrap-around design that blocks light from all directions.
• The frames and styles are intended to both fit over prescription eyeglasses or be worn on their own.
• These glasses may also be used as regular sunglasses.

PHASE-SHIFTING BASICS

Our body clock responds to a variety of cues' in our environment, the strongest of which is light. NASA research proved that a pulse of sufficiently bright light at the appropriate time will move (or 'phase shift') our body clock forward ('phase advance') or back ('phase delay'). This science is now being used to adjust our body-clocks to a new time zone (and avoid 'jet-lag') or shift to a new work schedule e.g. night work (and avoid 'shift-lag').

Phase shifting requires both a 'seek light' phase, and an 'avoid light' phase. Our new selection of special 'light blocking' glasses are intended for use during the 'avoid light' phase. Most ordinary sunglasses do not block out enough of the critical 'blue' wavelength to be effective for use during the 'avoid light' phase (blue wavelength light is responsible for shifting the body-clock; if exposure occurs during the ‘avoid light’ phase, phase shifting will be adversely affected).

Our new selection of light-blocking glasses have been sourced from the leading manufacturers of quality specialty eyewear. The lenses are specially formulated to block between 80% - 98% of incident light in the blue range (varies by model). The frames and styles are intended to both fit over prescription eyeglasses or be worn on their own.

All models will serve their desired purpose of blocking out the unwanted blue wavelength light during the 'avoid light' phase – and accelerate your body-clock's adjustment to the new preferred time.

Light-blocking glasses come with custom carrying case; some models also come with cleaning cloth.

Light Blocking Glasses are sold separately. Vistana model is also sold as part of the Litebook® Day & Night™ System.
