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

Very light, excellent optics
Loved the light weight and how it was designed to adjust to different fits! Great look!
These glasses are working very well for me. I thought I might need a darker tint after I first tried them on, but they are very close to perfect in the sun. So light I barely know they’re on.
They are comfortable, lightweight, and offer a level of protection I've never experienced before.
Love the enhanced vision I use it driving in the rain and of course playing golf which I why I bought it.
Better than all my Oakley
Great glasses except the falls off easily when on hats!
I bought these for my wife and she told me what she wanted to suggest. The lenses are very good, but she didn't like that the arm (temple) of the frame. It didn't hung the head well, they were not stiff enough, too flexible.
I’ve never experienced anything like the Nagai Carbon glasses. They’re unbelievably lightweight, and the lenses make everything look crystal clear, almost like seeing in HD. It’s one of those pieces you don’t realize you need until you try them.
