ASTRA NIGHT LENS

These glasses are designed to protect you from artificial blue light exposure, blocking 100% of the blue light spectrum. The red lenses completely filter out light from screens, LEDs, and electronic devices, helping to improve sleep quality, reduce eye strain, and enhance nighttime recovery.

Perfect for evening or pre-sleep use, they combine style, performance, and well-being in one essential accessory.

Use them 2–3 hours before bedtime or any time you’re exposed to artificial light at night — such as watching TV, scrolling on your phone, or working on your laptop.

They’re not ideal for daytime use since they block too much natural light and color. For daytime screen use, we recommend yellow-tinted COSMOS lenses that reduce eye strain without disrupting circadian rhythms

By blocking blue wavelengths, these glasses prevent light-induced suppression of melatonin, the hormone responsible for regulating sleep cycles. This helps you fall asleep faster and improves sleep quality and recovery.
