Photochromic and tinted lenses both protect your eyes from sunlight, but they work in different ways. Photochromic lenses automatically darken when exposed to UV light and become clear indoors, making them ideal for everyday use. Tinted lenses, on the other hand, provide a fixed shade designed for consistent glare reduction, especially for driving and outdoor activities. This guide explains the key differences, advantages, and best use cases so you can choose the right lenses for your lifestyle.
