WHAT DEFINES US
How do photochromic lenses work?
The EVO+ lens contains photoreactive molecules integrated directly into the polycarbonate. These molecules change structure in the presence of UV rays: they darken. When UV exposure decreases, they return to their original form and the lens becomes clear again.
A reactive, automatic system. No batteries, no switches.
How long does the adaptation take?
The transition to the dark tint takes approximately 30 seconds when exposed to UV light. The return to the clear tint is more gradual, taking about two to three minutes depending on the ambient temperature. In cold weather, the lens darkens faster and remains dark longer.
In practice, the transition is continuous. You won't perceive a break between the two states once in motion.
What makes SPEK different?
SPEK is built around what truly matters to the athlete. No over-designed elements, no unnecessary gadgets, no futuristic promises. Just comfort, clear vision, zero fog, and a style that keeps up with current trends. The fundamentals, executed without compromise. That's SPEK.
Do your lenses compare to the best on the market?
Yes. SPEK works with manufacturers that produce some of the best lenses in the sports industry. UV400 protection, SPEKTRA+ contrast and EVO+ photochromic technologies, performance-level optics. Access to quality shouldn't be a luxury.
What sport are they designed for?
SPEK was designed around road cycling and running. These are the disciplines that guided its development and field testing. Meeting the demands of a cyclist and a runner means covering the essentials: stability in motion, ventilation, lightness, and clear vision at high speeds. These fundamentals serve trail running, gravel biking, hiking, or cross-training equally well. Designed for performance, open to all terrains.
