About Umizato

Umizato Blue Light Blocking Glasses are the lightest around. We make the glasses from innovative, durable, and beautifully-handcrafted materials.

All our glasses have innovative clear lens technology with low color distortion. This lens technology blocks harmful blue light coming from digital devices.

Fit / Sizing Guide

All our styles have dimensions listed in the product description and photos. Measurements are in millimeters and represent lens width, nose bridge, temple (arm) lengths.

Like this example: 53-16-145

A great way to know what fits you the best, is to compare the measurements with your current glasses. Our frames come in Small, Medium, and Large sizes. See the size guide below:


Small                 < 50mm

Medium             50 - 54 mm

Large                 >= 55mm

When it comes to your face shape and glasses frames, a good rule of thumb is to look for frame shapes that contrast the shape of your face:

     • face with angular features soft and curved-shaped frames

     • face with rounder features angular-shaped frames

Lens Technology

Umizato glasses have innovative clear lens technology with low color distortion. Unlike others with yellowish tint, our glasses have clear (minimal tint) lenses.

These lenses will filter out 30% of the artificial blue light and 100% of the harmful UV wavelengths coming from digital screens. As a result, it helps you sleep better, rid headaches, and look great!

Unfortunately, we don’t. At the moment, we only offer blue light blocking lenses without prescription/magnification. However, we are coming out with reading magnification powers soon, so stay tuned!

Warranty & Proper Care

Use a lens cleaner spray, if available, to clean the lenses’ dust and other debris. If this is not available, use a lotion-free dishwashing soap and clean tap water.

The microfiber cloth that comes with your glasses is effective in removing any dirt or smudge from the lenses. Use it to dry the lenses and trap oils to avoid smearing. Make sure you clean the cloth frequently.

Avoid leaving your Umizato glasses in the car or any heated place for an extended amount of time. This can affect the AR (anti-reflective) coating and/or alter the shape of the frame.
