Tifosi Optics

Got them for running - I liked the slit in the "glass" to prevent fogging & that works. Snug fit - I wouldn't use them for everyday, but for activities - yes. Also, the glass doesn't come down on my face like I'd like it - I can look down & see the road without shading (my hang-up).

I love the look of the glasses. Didn't quite fit as well as I would've liked. Really light weight, also a nice glass case.

I use these glasses when I bike. The dark lesses are sharp and, I feel, protect my eyes from the sun and debris. Also, the frame hugs my face tight, I feel like they will ever fall. If you buy them, you should also try the pick lenses, specially if you go to the beach; they literally made everything look so much better, sharper, and sweeter, very relaxing!

At 25%-75%, perfect for the SF Bay Area where it's usually not too bright. They work well in the dark as well and transition fairly quickly.

I got these for cycling, I would get headaches when riding with my Oakleys on rides longer than an hour, I do not even know these are there. They are very light and they do not fog. They are highly recommended.

These are great-a good cross between sport & still a bit trendy. They are great for running. Super clear & lightweight - I've had many pairs of Oakleys. I might like these even better, and the price is much less.

I have a small face and always have a problem finding sunglasses that look good and fit right. These fit just fine and I have been very happy with them. In fact, I lost my original pair and am ordering another. They breathe well, and even running in the South Florida heat and humidity, they don't fog up. They don't move around when running, and the nose piece is comfortable. The wrap around style keeps the wind out of my eyes whether I am running or cycling. I like the interchangeable lenses, and will use these for golfing as well. I have a smaller head, and oftentimes the ear pieces stick out at the back of my head, but these seem to wrap nicely. Overall I am very satisfied with these glasses, I think they are a great value, and I would recommend them to friends.

I love these glasses! They are perfect for running. They do not slide when I sweat and they fit perfectly (although I do have a smaller head).

Very good glasses for the price. They fit great and are very light, great for running. I've got a smaller face and wrap around/big lenses usually look odd on me, but these look good.

The sunglasses are plastic and have a bit of a cheap feel to them, but they do fit well and suffice for my needs. Zappos shipping is crazy fast!

These are the most comfortable sunglasses I have ever worn and cut out all the glare. They are awesome!

These sunglasses are a bit big on face. The lense change is not particularly easy, takes a bit of time. The lenses are not good. Comparing to other glasses the eye protection on these glasses is really mediocre.

Wow! These are a great deal -- interchangeable lenses make this seem like 3 new pairs of sunglasses. These are comfortable, effective, and stylish. I have a narrow face, and these fit well.

I wanted a lightweight pair of glasses for running and biking with photo-chromatic lenses that would allow me to wear them very early in the morning and into daylight. I haven't ridden in them yet, but I've done several long runs and the glasses have been very comfortable and transition well from almost clear to a nice tint. The fit is listed as Small to Medium faces, but I'd say the their more like Medium to Large. Overall I'm very happy with them and of course, Zappos service can't be beat.

Zappos provided a very fast delivery. These are nice glasses, they are very comfortable; however, the lenses were more yellow and not green. When worn, everything appeared yellow and not true to color. I was disappointed. They did not seem to darken in the sun either. They are not dark enough for sensitive eyes. There was a defect in one lense so I had to return them. Zappos provided a fast return and credit! Overall Zappos provides excellent customer service!

I have very small face and these glasses sit very high on the face. 3/4 of the lens sits above the center of the eye. Horrible fit.

They do fit nicely and I like ths style and color; however, the lenses are not dark enough and do not adequately keep the sun out of my eyes.

Sunglasses fog up quite a bit (during conditions that cause this). Otherwise comfortable and do the job.

Well, this isn't exactly what I wanted. The outside isn't as mirrored as my previous pair, the tint is slightly browner and the lenses are a fraction bigger. But I can't find the older Gavia and this will do.

I love these sunglasses. They are big enough to block wind and glare while cycling, but the vents on the side help prevent fogging (although not always). Their great coverage means no squinting or blinding. The three lenses are handy and the mid-rage rose is perfect for lower-light situations. The grips on the nose and temples are truly no-slip (and I sweat a lot).
