Lens Care for NINES® NIRTECH® Sunglasses

Sep 30, 2025

Your sunglasses are the best companion throughout the day – on drives, hikes, weekend out for all long sunny days. But dust, fingerprints, and smudges can easily get in the way of a clear view. So, taking care of your nice pair of NINES® NIRTECH® polarized sunglasses keeps them looking fresh and working the best during any time of the day, and your eyes stay cool and protected every time you step outside.

Why Careful Cleaning Matters

NIRTECH® lenses have the best coating technology that uses a patented low-heat, pressurized process to form and shape. This special process allows both our lenses to embed the infrared and high contrast layer to protect wearers’ eyes.

Well, you can use your shirt to just wipe out some dust, yeah, sure. But the fiber on your shirt may start scratching off the top coating that blocks UV. In the long run, it will also reduce clarity and shorten lens life.

Proper care for your NIRTECH® polarized sunglasses can extend its protection and ensure NIRTECH® protects you from harmful sunlight to your eyes.

Clean NINES® NIRTECH® Polarized Sunglasses

Avoid harsh chemicals that may cause damage to the coating. If just small smudges, use the microfiber cloth that comes with the case from NINES®.

Most of the lens-safe cleaning spray is another option. At the same time, you are doing deep cleaning on your favorite pair. Make sure to use lens-safe cleaning spray, which helps prevent coating damage and also removes hard stains that stick to the glasses.

Gently rinse with lukewarm water before deep cleaning with lens-safe spray. It’s the best choice for performance users who enjoy outdoor activities such as hiking, fishing, or cycling.

If you want to put your NINES® away, use the NINES® protection case. The case is designed to keep your favorite sunglasses safe and prevent impact.
