The Shinzo Tamura Difference

TALEX polarized lenses are engineered to filter harmful UV light while enhancing clarity and contrast — preserving visual detail without simply darkening the scene. Each lens is handcrafted in Osaka, Japan.

Ultra Light

Shinzo Tamura frames are designed for balance and ultra-lightweight performance, using non-aging nylon for durability. Double-molded construction enhances flexibility while maintaining structural integrity over time.

Perfect Fit

Our adjustable, non-slip nose pads are made from skin-friendly elastomer, providing secure fit across a wide range of face shapes. Flexible titanium arms relieve pressure, allowing for extended wear without fatigue.

Great sunglasses

Light, good for high cheekbones, pyrite tint best for light to moderate sunlight, shade does a good job of enhancing the scenery without distorting the color. Wide faces might find the lenses a little small

So very sad 😢

So I just LOVE my new Nagai frames! Unfortunately, I can't find anybody who will install prescription lenses in the Nagai frames. I'm SOOO disappointed ☹️. Any advice?

Hi Mary, we're glad you love your Nagai frames! They are our lightest sunglasses and the frameless design is perfect for being active.
Because they are a frameless design, they are not easy for optometrists to make Rx lenses for. The lenses need very specific and accurate placement of attachment features that are cut into the lens, and not every optometrist is equipped to do this. It's also not as easy to find thin Rx lenses with this high degree of curvature.
We are currently working on making our prescription lens service available to US customers, and we are hoping to be able to take Rx orders soon.

Perfect

Very impressed. Light, comfortable. Great lenses. Best sunglasses I have every worn

Perfect Golf Sunglasses

Very light on the face - didn’t fidget with them all day.
Was not sure they would be dark enough but actually seem to be perfect.
Clear vision - these do not disturb my depth perception!

My all time favorite lenses

I dislike tinted lenses because the warmer color gradient or the yellow-ish cast gets tiring for my eyes. However, grey lenses have always been too dark for me, to where I feel that I can't see the world clearly. These quartz lenses have been what I've always been looking for. The world looks crystal-clear, the glare is gone, and the frame is so lightweight, too, that I forget that I am wearing anything until I go indoors. For someone who's always hated sunglasses but needed them in the water or white sand deserts, these are just what I've needed. A perfect pair of sunglasses that doesn't squeeze my temples, doesn't slide down my face on my Asian nose, and doesn't touch my cheekbones like so many other performance sunglasses do. If there were only one thing I could add, I wish these were safety-rated like the Zircon lens. Otherwise, they are perfect.
