A small fit and lenses that automatically adapt to the light.

A runner, hiker, or biker with a small face will appreciate the compact fit and versatile technology of the Tifosi Radius Photochromic Sunglasses. At just 24 grams, these sunglasses are one of Tifosi's most lightweight models, but nothing was sacrificed to keep the weight so low. You still get vented, interchangeable lenses (like many other Tifosi multi-sport shades), and the Radius even features photochromic lens technology. In a matter of seconds, the Radius' lenses automatically lighten or darken to match the ambient light levels so you're never in the dark when clouds roll through or blinded by the light when the sun suddenly comes out.

  • T90 Grilamid frame is lightweight, highly durable, and features a small fit
  • Hydrophobic nose and temple padding relieve pressure at your nose and above your ears
  • Photochromic lens technology allows each lens to automatically lighten or darken its tint to match the ambient light levels
  • Interchangeable lens design means you can swap the lens out of the frame with a simple pull and pop back in with an easy push (if you want to switch to a non-photochromic lens)
  • Lenses are vented to reduce fogging so your vision stays clear
  • Bag and case are included

Does the job

  • Familiarity: I gave it as a gift but have feedback to share

These were a gift for my wife and they are her go-to for all outdoor activities. The lenses transition quickly and have a broad range. They also stay in place very well. They do seem to run on the narrow side.

Great glasses, built for a narrow face

  • Familiarity: I've used it several times
  • Fit: Runs small

Terrific glasses ... I usually wear Smith, however tried these on thanks to them being on a sale. They are very well built - tough, nice finish, vent really well, photochromatic lenses are perfect for San Francisco weather. Fit is tricky, these are built for a narrow face and may be extra tight for some.

Unanswered Question

It's a little unclear in the description. Do the photochromic glasses also come with additional lenses?

A little small for my head

  • Familiarity: I've used it several times

I like the lense features of these glasses, but I feel like they don't give enough eye coverage for my face. Think they would work better for someone who has a narrow face.

I still use these for running all the time, and don't have any venting issues. The clarity of the lenses are great.

Nice Shades!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Love the fit. The lens are super sweet how they change with the light. Lightweight, but made durable.

I recently bought another pair because they are so great! My first pair is still in working condition but I knew I wanted to have these for awhile so I have a spare pair for when I need them. The fit is great for smaller framed faces. These things are very durable too! Get em!

Nice Shades!
