The NightShield blue light blocking glasses block 100% of blue and most green light, ensuring the most effective protection on the market. They support the secretion of natural melatonin. We only use them 3-4 hours before bedtime.
The main purpose of using NightShield is to reduce the impact of blue light on the body and eyes after dark. Effects that can be obtained: improving sleep, regeneration and energy levels during the day as well as reducing eye strain and waking up at night. The effects are felt after 1-3 nights of reliable wear. We don't wear them during the day or while driving - it's worth getting DayShield for this.
