Not all light is created equal and the wrong lighting at the wrong time of day can ruin your sleep, performance and health. Your entire physiology is impacted by the spectrum of light that is absorbed by your eyes. Unfortunately, we are surrounded by “junk light” from nearly all artificial light sources including LEDs, computer screens, florescent lights and TVs. The blue light spectrum is the most talked about culprit of circadian rhythm disruption in today's modern world. Circadian disruption has been attributed to the increase of risk of heart disease, depression, learning issues, obesity, and more. Truedark yellow lensed eyewear is ideal for users who work/live/play in environments that are lit with artificial blue light emitting fixtures and are exposed to long periods of time utilizing blue light emitting devices (TVs, computers, tablets, phones, etc). Yellow lens glasses are ideal for people who suffer from disrupted sleep-wake cycle/circadian rhythms. Yellow lens eyewear is also ideal for shift workers as they can be more sensitive to artificial lighting during the dark hours they are awake, which disrupts their natural sleep-wake cycle/circadian rhythm. 75% of blue light is blocked with our yellow lenses. Our yellow Lens styles are a great solution if you work in a profession where a colored lens isn't the right style, draws too much attention, or interferes with your work. Combined with nighttime use of TrueDark Twilight glasses, you'll experience 24 hour protection from junk light.
