Kona TT Bifocal — Photochromic Cycling Eyewear
For Riders Who Need Near & Distance Vision on the Road
Photochromic lens. Bifocal magnification. One frame.
The Kona TT Bifocal combines the light-adapting performance of a photochromic lens with a bottom bifocal segment for reading — so you can check your cycling computer, read a map, or review your nutrition plan without removing your eyewear. Available in 10 frame colors with three magnification strengths.
Who is the bifocal for? Cyclists and triathletes who need reading magnification on the bike — for bike computers, nutrition labels, or course maps — without sacrificing the light-adjusting performance of a photochromic lens.

Kona TT — Photochromic Cycling & Running Sunglasses
10 Frame Colors. 10 Lens Options. Built for the Road.
Light-adjusting lenses. Zero compromises.
Fixed tints force you to choose between too dark or too bright. The Kona TT adapts automatically — photochromic lenses darken in sunlight and clear in shade, so your vision stays optimized from the start line to the finish. Choose from 10 frame colors and 10 lens options including photochromic, clear, smoke, yellow, and more.
Why photochromic? Cycling and running conditions change fast. Cloud cover, tunnels, tree canopy, open road — your lens has to keep up. The Kona TT transitions in seconds so you never have to stop to swap lenses mid-ride or mid-race.
