Are the glasses and lenses high quality?

All of MARK O’DAY’s sunglasses are classified as category 3 and have UV400 protection, which protects your eyes 100% from UV sunlight rays.

Likewise, all of MARK O’DAY’s sunglasses have all of the European Union quality certificates.

Recommendations for proper sunglasses care:

Avoid leaving your MARK O’DAY’s in places where they may be exposed to high temperatures and receive sunlight for prolonged periods of time. Avoid leaving your sunglasses upside down as the lenses may be damaged. Also, always use the rigid case that MARK O’DAY gifts you for transport, and the microfiber cloth for cleaning.
