The basic performance of the lenses is also top-notch! Just like how your image is reflected in window glass, the same phenomenon occurs with eyeglass lenses. The reflection of light causes such a phenomenon. To prevent reflections, it is important to suppress them. The lower the reflectivity, the more effective it is. While lenses without anti-reflective coatings have a reflectivity of around 8% to 10%, anti-reflective multi-coating achieves a low reflectivity of approximately 1%. Furthermore, preventing reflections also leads to improved light transmission, making it possible to brighten the field of vision. Precautions regarding photochromic lenses Photochromic lenses are easily affected by temperature changes; the lower the temperature, the greater the color development effect, and the higher the temperature, the less the color development effect tends to be. Also, they will not change color inside cars with UV-cut glass.
