Care

Tens are designed to be robust, durable, scratch-resistant and provide superior comfort. Always keep the lenses free from dirt, debris and contact with rough surfaces. We recommend that you frequently clean your sunglasses by rinsing with water to remove dust and dirt, and using the microfibre bag or soft material to dry. Avoid all types of solvents and alcohol when rinsing. Following these steps will minimise any damage or alteration to the frame or filter characteristics.

Storage

When not in use, store inside the microfibre bag and/or hardcase provided in a dry place out of direct sunlight, at a temperature between -10 and +35 degrees Celsius.

Wear & Tear

Acetate isn’t brittle like plastic you’ll find in regular sunglasses, it can be modified and shaped to fit your size and use. If your Tens become out of shape over time, you can take them to your local optometrist for adjustment.

If the hinge screws loosen over time, these can be tightened.

Tens is not liable for any damage.
