Moira Brown Photochromic Lens Glasses – Tortoise Round TR90 Frame

Warm Contrast for Changing Light

Brown photochromic lenses stay clearer indoors and darken outdoors in sunlight—adding a warm tone that brings extra depth on trail & terrain days and course walks. When the light shifts from shade to open sky, they help take the edge off harsh glare without looking overly dark inside. Paired with the Moira round frame in Tortoise, the ultra-light TR90 build keeps the vibe classic and easy. The result is one pair that moves smoothly from coffee runs to weekend adventures.
