First of all, a very important premise, are photochromic lenses suitable for your purpose and environment of wearing glasses? If it doesn't fit, the issue isn't much to discuss. Your use environment is not suitable for photochromic lenses, why do you buy them? Are the lenses really stupid?

Photochromic lenses have a history of more than 60 years. I believe they are older than most of the people who discuss this issue here. There must be something special about them that have existed for so long, otherwise they would have been eliminated long ago. Most photochromic lenses are UV-sensitive, that is, they change color in an environment with ultraviolet radiation, otherwise they will fade; a small part is infrared-sensitive, which is more sensitive.

The photochromic lenses  is mainly designed for outdoor environments, which can effectively block ultraviolet rays and protect the eyes. It is definitely an eye-protecting tool for outdoor sportsmen. Those who say that the color does not change in the car or in the house are all poisonous? You haven't even figured out the use environment, you are adding to yourself with a photochromic lenses .

Powerful photochromic lenses, the color change/fading will be completed within 1-3 minutes. For those who say that the color fades in 10 minutes, I can only say that you get what you pay for. This is your own choice. Don’t complain about the product. There are also those who say that you can't see other colors after changing the color. I am really speechless. You are wearing color-changing glasses. What are you thinking?

Photochromic lenses are not your only choice, friends who like cool, some tips:

  1. If you are afraid of the sun while driving, please wear polarized sunglasses, this is the correct and safe choice (polarized light is very important)
  2. Those who are short-sighted and want to wear sunglasses can wear prescription sunglasses, and they can have a polarizing effect
  3. If you want to take into account myopia glasses and sunglasses, but don't want to use sunglasses, you can choose photochromic lenses

It is recommended that no matter what product you choose, you must understand the product features and your own expectations to make the right choice.
