What are photochromic lenses?
Photochromic lenses are also known as transition lenses that change color by reacting to UV light. These lenses have thousands of light-sensing molecules on their surface that change structure when the UV rays fall on them. These glasses are perfect for people who need the functions of both prescription glasses and sunglasses from one pair. These glasses are clear indoors and darken in the sunlight to protect your eyes. Specscart has a smart collection of transition lenses that react to the light quickly and darken as soon as you step into the sunlight.
