Blue light blocking glasses are designed to filter out high-energy blue wavelengths from screens, which help reduce digital eye strain, fatigue, headaches, and disrupted sleep – caused by digital screens. We have helped many people and professional athletes get more relaxed at night, along with deeper sleep. Not magic. Not hype. Just smart protection for your eyes and sleep.

It depends on which of our lens you are using. During the day (Relief Lens)  – If you work at a screen, blue light glasses can reduce eye strain, blurry vision, and tension headaches.In the evening (Relax & Relief Lens) – Wearing them after sunset helps your body produce melatonin naturally, which is essential for falling asleep. Before bed (Sleep & Relax Lens) – Scrolling in bed? That’s the most important time to wear blue light glasses, as screens at night send the wrong signals to your brain.

Blue light itself isn’t bad – but it’s all about timing. Natural blue light from the sun is beneficial during the day. It helps keep us awake, alert, and regulates our natural body clock. Artificial blue light from screens – especially in the evening – is the real problem. Blue light after sunset suppresses melatonin by up to 70%, disrupts your circadian rhythm by 3+ hours, makes you 50% less tired and it takes you up to 30 minutes longer to fall asleep.

Night Shift only reduces blue light by about 20-30%, while HEVO lenses block up to 99%. Your phone's Night Shift is a good start, but it doesn't affect your room lighting, TV, laptop, or the dozens of other blue light sources around you. Plus, it still lets through 70-80% of the harmful wavelengths. HEVO works on ALL blue light sources in your environment, not just your phone. That's why customers still see dramatic sleep improvements even when they were already using Night Shift. Think of it this way: Night Shift dims the problem, HEVO solves it.
