- To avoid scratches, never clean your sunglasses with paper towels or clothing. Just use included cloth.
- To avoid damage, never clean your sunglasses using household detergents or soaps. Just use clean water.

For every pair of sunglasses sold, plants one tree. We choose to support Operation Homefront.
This is super important to us to give back and help aid in the reforestation efforts domestically and internationally. Trees help clean the air we breathe, filter the water we drink and provide habitat to over 80% of the world's biodiversity. Forests provide jobs to over 1.6 billion people, absorb harmful carbon from the atmosphere, and are key ingredients in one-quarter of all medicines.
