Photochromic lenses are just like normal lenses but they automatically become dark when we move in the sunlight. Ultraviolet rays coming from the sun affect the molecules present in the photochromic lenses therefore, these lenses change their colors. These lenses get darker in bright lights and vice-versa.

Photochromic lenses and polarized lenses i.e. sunglasses are very different from each other as the sunglasses have a set tint that protects our eyes from glares but they are not changeable whereas the photochromic lenses easily adapt to the nature of the light present around and changes accordingly.
Regular sunglasses block out only a particular amount of wavelengths of light with polarization. But the photochromic lenses are carbon-based therefore, the molecules present in the lenses react to the UV, this leads to the change in shape as the lenses absorb the light and it seems to look darker. The darkness of the lens depends on the amount of light present, the brighter the light the darker the lenses. The darkening of the lens takes up to 30 seconds and it can take 2-5 minutes to get back to normal when an individual goes back to an indoor area.
