Photochromic lenses, also known as Transition lenses, have many advantages, including: UV protection Photochromic lenses darken automatically in sunlight to block up to 100% of harmful UVA and UVB rays. This can help reduce the risk of cataracts and eye damage.       Low light vision Photochromic lenses can improve vision in low light conditions, such as at dusk or indoors. This can be helpful for people who have trouble seeing in low light or drive at night.     Convenience Photochromic lenses can eliminate the need for a separate pair of sunglasses. They can be worn in a variety of lighting conditions, and are available in many different styles, tints, and shades.      Cost-effective Photochromic lenses can be more cost-effective than buying separate glasses for different lighting conditions.    Blue light protection Photochromic lenses can help protect eyes from harmful blue light, which can cause digital eye strain and oxidative stress in the retina.  #foryou
