Eyeglass lenses are not just eyeglass lenses. There are now many glasses with different shapes, colors and functions on the market. We will explain to you which lens is suitable for which requirement and what the difference is between polarized, mirrored, tinted and self-tinting lenses.
Tinted lenses for optimal sun protection
Tinted sunglasses offer optimal sun protection and are irreplaceable for outdoor sports or leisure time in the sunshine. The glasses filter the disturbing, visible light. This avoids glare and enhances contrasts. This guarantees optimal visibility in sunshine. Eyeglass lenses can be tinted differently. There are simple color gradients or bicolor (lighter downwards) color gradients. The desired tint is achieved by dipping the glass or evaporating a layer of paint. In addition to the respective tints, there are also filter categories (CAT. 0 to CAT. 4). The categories are for guidance and indicate how much light passes through the lens and what conditions a lens is suitable for. You can read more about the filter categories here.

Self-tinting lenses (photochromic lenses): What does that actually mean?
Photochromic, i.e. self-tinting lenses, are becoming more and more popular and are in vogue. The lenses adapt to the lighting conditions and automatically become lighter or darker. This allows you to cover different light and weather conditions with sports glasses. Photochromic sports glasses are particularly suitable for cycling or running, where different conditions are often encountered.

What are polarizing lenses good for?
Have you ever heard of polarized lenses? With polarized glasses, the lenses are fitted with a polarizing filter (polarizing filter), which minimizes glare and ensures that you can see contrasts and colors better and that the rays reach the eye weakened. Polarized sports glasses are particularly recommended for activities in the water or on the mountain, as you are exposed to different light conditions there. But how does the Polfiter work? When light, which is radiated in different directions, hits a flat surface, the light rays are reflected horizontally and vertically. The vertical rays of light are then absorbed by the polarizing filter. Would you like to learn more about the process of polarized lenses? In our blog article on polarized sports glasses, we have listed all the important advantages and disadvantages.
What effect do mirrored lenses have?
Who does not know them - sunglasses with mirrored lenses. In contrast to polarization or a tint, the mirroring has no function, but fulfills a purely aesthetic purpose and rounds off your style. Mirrored sunglasses are not only an eye-catcher in your free time, they are also trendy among sports lovers. For this reason, many sports glasses are mirrored.
