HELIOS BLACK DAY LENSES

These glasses are designed to protect you from artificial blue light exposure, blocking 50% of the blue light spectrum. The yellow lenses filter out half blue light from screens, LEDs, and electronic devices, helping to improve sleep quality, reduce eye strain, and prevent fatigue.

Perfect for day time use, they combine style, performance, and well-being in one essential accessory.

You should wear your COSMOS yellow lens glasses during the day — especially when you’re exposed to artificial light or spending long hours in front of screens.

They’re not ideal for nightime use since they don´t filter full blue light spectrum. For nightime screen use, we recommend red-tinted COSMOS lenses that block 100% of blue light preventing circadian rhythm disruption

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.
