The sunglasses have gradient lenses,
The gradient color starts from the darker color at the top of the lens,
Then gradually brighter tones toward the bottom of the lens.
These tones are very helpful for fashion and for reading outside on sunny days.
The working principle of gradient lenses is to allow a certain amount of light to pass through certain areas,
And even less where protection is most needed.
