Size guide


We offer you free U.S. shipping and hassle-free 30-day returns for all orders. If you are not happy with the product for any reason, you can return it within this time period.

Please refer to our full return policy for more information.

We are so confident in our products that we offer you a sleep better guarantee. If you are not absolutely delighted with the results within 30 days, we insist that you tell us, and we will refund you with no questions asked.

For the best results, put the glasses on 45 to 60 minutes before bedtime, and make sure to turn the lights off before you put them on the bedside table. The blue-light-blocking effect will get reduced if unfiltered light reaches your eyes.

Consider setting a reminder on your phone to remember to put them on every night.

BLSE™ Tech – 99.5% blue-light blocking
Our Blue Light Spectrum Elimination technology filters out 99.5% of all blue light and over 70% of green light, optimal for your sleep. Protect your eyes from harmful blue light while letting in maximum amounts of safe light for clear vision.

Advanced nylon blue-light-blocking lenses
With our years of experience, we created the next generation of blue-light-blocking lenses. This second-generation lens is made of nylon, the most advanced lens material. It has superior scratch resistance and clarity compared to cheap alternatives like CR39 or polycarbonate/PC.

Luxurious cellulose acetate frames
Enjoy a perfect fit with reshapable lightweight acetate frames paired with flex stainless steel spring hinges. This premium, environmentally friendly alternative is used by luxury brands for its superior quality.

Sustainable premium materials
All our products have been carefully developed with the best materials for eyewear, including cellulose acetate frames and nylon lenses. These materials offer the most sustainable, long-lasting, and hypoallergenic product for the planet and your peace of mind.

Anti-reflective coatings on front and back
We went even further in achieving the best possible performance and experience for you, our customer. After creating the best blue light filter lenses, we reinforced them with anti-reflective coatings on both the front and back. Only the best is good enough. (Rimless and Rectangle in Crystal color do not have anti-reflective coatings yet – to be updated soon.)
