G-LENS CHANGE SYSTEM
A practical system that allows you to change lenses to match your glasses to current weather and lighting conditions. Eyeglasses equipped with the intuitive lens replacement system come with at least one set of additional lenses and a hard case. Each model with an exchange system comes with a base lens that finds use on sunny days. Depending on the model, the set may also include clear lenses to protect the eyes from wind, mud, insects, or contrast-enhancing lenses (yellow/orange/pink) that are perfect for low-light conditions.
