Have you ever seen a scene in a sci-fi movie where the protagonist's glasses instantly change color in the sunlight, from clear to dark, adding a bit of mystery to their eyes? Today, this kind of sci-fi scene is no longer a distant dream, because photochromic lenses have already entered our lives.
Profile
Photochromic lenses are transitional lenses that change color when exposed to sunlight or ultraviolet light. This change is not just a simple shade, but a gradual change from clear to dark, as if the lens has a life of its own and can adapt to the changing environment.
Principle
The principle of photochromism is simple. The lenses contain a special substance that, when exposed to ultraviolet light or sunlight, absorbs energy and undergoes a chemical reaction that results in a color change. When the lens is in the dark or out of direct sunlight, the substance gradually releases the energy and returns to its original transparent state.
Advantages
Automatic light adjustment: Photochromic lenses automatically adjust color according to light intensity for a more comfortable viewing experience.
Protects your eyes: In bright light, the color of the lenses darkens, effectively reducing the damage caused by ultraviolet rays to the eyes.
Fashionable and practical: Photochromic lenses are not only practical but also fashionable. Whether in everyday life or outdoor activities, they can make you the center of attention.
How to select?
When choosing photochromic lenses, we need to consider several factors:
Brand and quality: Choosing a famous brand and a product with guaranteed quality can ensure the quality and color changing effect of the lenses.
Color change speed: The speed of color change may vary from one lens to another, it is very important to choose the speed of color change that suits your needs.
