A high-contrast lens enhances the detail and colour of your vision by actively filtering out the « in-between » wavelengths in visible light. It creates « steps » in light, allowing you to see more of the terrain ahead.
Performance high-contrast sunglass lenses demand more than just darkening your vision. They bring out the detail. Under full light, an abundance of light can end up looking « flat », grey, and overwhelming to the eye and brain. High-contrast filtering brings out the detail of your vision.
You might think that a yellow object reflects only yellow wavelengths. « Yellow » is actually made up of a mixture of wavelengths. While running through a dense forest, or cycling up a hill under bright sunlight, most of the colours we see do not correspond to a single wavelength but to a mixture.
High-contrast lenses enhance the difference between orange dirt and red leaves by actively filtering out the wavelengths in between red and orange. It creates « steps » in light, a larger difference that allows you to see more of the terrain ahead.

When trying on high-contrast glasses, we recommend wearing the lens for at least 5 minutes to allow your brain and eyesight to adjust to the technology. Once your eyes adjust, the lens colour « disappears » and the difference between with and without becomes more striking.
Most SPEK lenses and frames are designed to be interchanged, enabling runners, cyclists, skiers, and snowboarders to finely tune their vision by choosing the right lens for the effort at hand.
