What's the difference between functional glasses and ordinary glasses?

Functional glasses are special glasses that can bring some beneficial effects and efficiency to people's eyes, instantly change their visual experience and make their vision more comfortable and pleasing to the eye.

Traditional glasses are "eyeball-adaptive glasses, and the degree increases year by year". In order to overcome this shortcoming, functional smart glasses can automatically adjust their functions with the change of environment, instantly change their visual perception to protect human health, and achieve the effect that "glasses can automatically adjust their functions to actively adapt to the eyes and improve their eyesight at the same time".
