enhance restorative sleep and promote better recovery

strong light-blockers for evening use

At nighttime, exposure to artificial light, especially from electronic devices can disrupt the body's natural production of melatonin, a hormone that regulates sleep-wake cycles. Blue light, in particular, has been shown to suppress melatonin production and delay the onset of sleep.

By wearing light blocking glasses at nighttime, individuals can reduce their exposure to blue light and other stimulating wavelengths, allowing the body to maintain its natural circadian rhythm and promoting the onset of sleep. This can result in improved sleep quality, faster sleep onset, and a more restorative sleep overall.

1. Blue and green light wavelengths, especially those emitted by electronic devices like smartphones and computers, can suppress melatonin production, which is essential for regulating sleep-wake cycles. Blocking these wavelengths can help maintain optimal melatonin levels, promoting better sleep.(Cajochen et al., 2011)

2.Studies have shown that filtering blue and green light wavelengths, particularly in the evening hours, can lead to improved sleep quality by reducing the disruption of circadian rhythms. This can result in longer and more restorative sleep periods. (Chang et al., 2015)

3. Blocking blue and green light wavelengths before bedtime has been found to alleviate symptoms of insomnia and improve overall sleep efficiency. This is particularly beneficial for individuals who experience difficulty falling asleep or maintaining sleep throughout the night.(Figueiro et al., 2012)

4. By minimizing exposure to blue and green light wavelengths in the evening, individuals may experience increased alertness and cognitive performance upon waking in the morning. This can contribute to a more refreshed and energized start to the day.(Chellappa et al., 2011)

Yellow lenses primarily target the blue light spectrum, filtering out wavelengths emitted by digital screens to reduce eye strain and improve sleep quality. They offer targeted protection against specific wavelengths associated with melatonin suppression. In contrast, red lenses block a broader spectrum of light, including blue and green wavelengths. While providing stronger overall protection and a bigger impact on sleep, they may slightly decrease visibility due to their darker tint. Red lenses are ideal for those seeking comprehensive protection against multiple wavelengths but may be less suitable for activities requiring precise colour perception.
