TrueDark is a wellness-tech brand focused on eyewear that aims to regulate light exposure in order to support better sleep, improved focus, and overall healthy circadian rhythms. They identify modern artificial lighting and screen-time modes as “junk light” — blue, green and violet wavelengths that disrupt the body’s internal clock — and build glasses with lens filters to selectively block those harmful wavelengths while preserving or enhancing beneficial ones. The product range is differentiated into daytime models (which allow a controlled amount of blue light to maintain alertness) and nighttime models (which filter nearly all blue and green light to signal the body it’s time to wind down). TrueDark emphasizes its mission to help individuals take control of their environment, so eyes and biology work in sync with natural cycles. The company offers global shipping, and supports a 30-day return policy and one-year warranty on manufacturing defects.
