UV Protection
The UV rays in sunlight can be harmful to the eyes.

Photochromic lenses and most quality sunglasses offer UV protection.
Scratch-Resistance
Scratches on lenses are distracting,
unsightly and in certain conditions even potentially dangerous.
They can also interfere with the desired performance of your lenses.
Scratch-resistant treatments toughen up the lenses making them more durable.
