Gradient lenses are predominantly chosen for fashion purposes to create a striking sunglass style.
While a Gradient lens delivers a fashion statement, there are also practical benefits.
One benefit is the protection offered at the top of the lens where it is darkest – this is where protection is needed most when the bright sun is overhead.
A Gradient lens is also useful when hiking or walking. The bottom of the lens is lighter so you can better see where you’re treading, and the top of the lens is darker for when the sun is overhead.
