    Wellington Frame

    The silhouette of this classic style was first released all the way back in the 1950s. Since then it had multiple periods of resurgence, in the 80s, late 00s, and again today, making it a truly timeless style.

    The Wellington has revolutionized the world of sunglass fashion forever. Some of them are true icons, like the Ray-Ban Wayfarer, or the Oakley Frogskins.

    Premium lenses

    All Shinzo Tamura frames feature premium polarized TALEX lenses, handmade in Osaka, Japan. The filter is designed to block 99% harmful UV rays - helping you keep your eyes healthy and see clearer.

    Perfect fit

    The non-slip nose-pads are made from skin friendly elastomer, providing the perfect fit. Flexible titanium arms relief pressure, and give Shinzo Tamura frames a distinct and classic style.

    I chose this brand because I’m Asian, and I wanted sunglasses that are designed for customers with Asian facial features. We typically have problems fining a pair of sunglasses that has a good fit, unless it’s from an Asian brand or a brand that makes “Asian fit” glasses.
    These are perfect. They don’t touch my cheeks and don’t slide down my nose.

    I picked these up because I wanted really high quality lenses. I have very light blue eyes, and I’m light sensible. First I was skeptical because the lenses are actually not very dark. But I learned that this is actually not important. It’s the polarization and all the coatings of this lens that make it work so well.
    They do a good job of explaining it on the website, but I also asked my eye doc about it, and he confirmed that a dark sunglass lens is not automatically better at eliminating UV rays. He recommended polarized lenses and said to go with a major brand. But I’m happy that I gave these a try after seeing them in my Google search.

    Really nice matte black frame. Feels very premium, especially with the metal accent on the frame. They are light and fit well. Can’t complain. Would definitely recommend them for anyone looking for an all-around great pair.
