To increase the lifespan of your sunglasses please follow the following steps:
When you are not wearing your sunglasses they should be clean and stored in the case provided to protect the lenz.
DO NOT store your sunglasses in direct sunlight, on the car dashboard or anywhere with extreme heat.
Clean sunglasses carefully using the Microfibre pouch provided. Blow away any dust before wiping.
It is ideal that you wash your sunglasses using a small amount of mild soap or optical lenz solution and cold water. Use an optical cleaning cloth or air-dry your sunglasses. Do not use a paper towel or your t-shirt as a cleaning or drying agent.
