Photochromic cycling glasses that adjust their own tint as the light changes, so you're not swapping lenses or squinting through shaded sections of a ride.
Overview
These glasses use photochromic PC lenses that darken automatically as UV intensity rises and lighten back up in shade or overcast conditions, so one pair handles a ride that moves between open sun and tree cover without a lens swap. A UV400 rating blocks harmful UVA and UVB rays throughout, regardless of how dark the lens happens to be at that moment.
The frame is TR90, chosen for its resistance to deformation and light overall weight, with an adjustable nose pad that lets you dial in a secure, comfortable fit. A built-in myopia insert mount lets wearers who need corrective lenses fit their own prescription insert rather than giving up sport sunglasses altogether.
The full kit includes a hard case, a pouch, and a cleaning cloth, so it's ready to use and properly protected from the first ride.
Why You'll Like It
Automatic light-adaptive tinting
The lens darkens or lightens on its own as conditions change, so you're not stuck choosing one tint for a ride that moves between sun and shade.
UV400 protection
Blocks harmful UVA and UVB rays at any tint level, so protection doesn't depend on how dark the lens currently looks.
TR90 frame
Resists deformation and stays lightweight, holding up to the bumps and flexing of regular riding.
Myopia insert compatible
Fit your own prescription insert rather than having to choose between your glasses and photochromic protection.
Who Is It For?
This suits riders whose routes move between open sun and shaded sections — tree-lined roads, tunnels, or trails with tree canopy — where a single fixed-tint lens is either too dark or too light depending on the stretch. It's a practical pick for early-morning or variable-light rides where conditions shift through the session.
Good to Know
Photochromic lenses take a short moment to transition when light conditions change suddenly — moving from bright sun into a shaded tunnel, for instance — so allow a beat for your eyes and the lens to adjust together. Store the glasses in the included hard case when not in use to protect the photochromic coating from scratches.
