Why use blue light blocking glasses?
Why use blue light blocking glasses?
Our glasses erase eye strain, headaches, and sleep disturbances caused by prolonged screen exposure (phone, computer, TV).
They also help you stay focused longer, improve your productivity, and reduce mental fatigue — essential whether you work or browse for hours.
How are these different from regular glasses?
How are these different from regular glasses?
Unlike standard glasses, ours are designed to block up to 98% of harmful blue light.
They also stand out for being eco-friendly, made from recycled materials to reduce environmental impact — a conscious choice for your health and the planet.
When should I wear them?
When should I wear them?
Anytime you're in front of a screen — for work, scrolling social media, watching Netflix, or gaming.
They’re also perfect as a daily lifestyle accessory, whether you're reading, commuting, or relaxing at home.
Can I wear them all day?
Can I wear them all day?
Absolutely. Our lenses are optimized for full-day use, blocking up to 98% of harmful blue light while preserving natural colors. That means all-day comfort without the yellow tint or distortion.
What size should I choose?
What size should I choose?
Our blue light glasses come in three sizes — Small, Medium, and Large — designed to suit different head widths and preferences for fit.
Here’s how to pick yours:
: Great for those who usually find glasses too loose or wide. If frames often slip down your nose or feel oversized, this size will likely suit you best.
I recommend the Medium size — it fits 90% of people perfectly and is almost always the safest choice.
: A universal fit that works for most people. If you’re unsure, this is the most popular and balanced choice.
: Perfect if you usually look for a wider frame or prefer a roomier, more relaxed fit.

Falling asleep used to take forever. Now? I pop these on after 8pm and I’m out like a light. Best sleep in years.

I spend most of my day in front of screens. These glasses have made a real difference less eye strain, better focus, and I even sleep better at night. Didn’t expect that at my age. Highly recommend.

Working long hours on my phone and laptop used to give me headaches and tired eyes. Since I started wearing these blue light glasses, my eyes feel fresh, and I can write for hours without discomfort. Plus, I sleep way better! Perfect for late-night creative sessions.

I used to feel drained in the morning after late-night screen time. Since I started wearing these glasses, I fall asleep faster and wake up clear-headed. I’m more productive at work and I have real energy to enjoy time with my daughter. Best investment I’ve made this year.

Customer Reviews
Costumava trabalhar horas extras e, por isso, a minha condição física não estava muito boa, mas notei uma grande diferença ao usar lentes noturnas. Meus olhos ficaram menos cansados, o que é ótimo. Acho que é perfeito para quem trabalha no escritório. Além disso, o design é bonito.
Super
I look beautiful with thank you
After just a week of wearing them, I’ve noticed a huge improvement in my sleep quality. I fall asleep much faster, and I wake up feeling completely refreshed. I also feel my recovery has improved; I feel less tired during the day.
I spend most of my day in front of a screen for work, and I used to get headaches and dry eyes by the evening. Since we started using these glasses, I've noticed a real difference — my eyes feel more relaxed, and the headaches are almost gone. For me, it’s now a must-have for protecting my eye health.
