What does gradient photochromic mean?
Gradient photochromic refers to a type of material, often used in eyewear or lenses, that changes color or tint in response to varying levels of UV light exposure, creating a gradient effect. This means that the lens will be darker at the top and gradually become lighter towards the bottom, or vice versa, providing both aesthetic appeal and functional benefits, such as improved visual comfort in different lighting conditions. The gradient effect allows for a stylish look while maintaining visibility and protection from sunlight.
