For maximum comfort, check the headstrap to make sure the webbing is untwisted, and the hinges are straight.
Use only the included microfiber bag to clean your sunglasses.
DO NOT leave glasses in direct sunlight, such as on the glare shield of airplane.
Flying Eyes Sunglasses include two different types of cinch for the headstrap. The default Lightweight Cinch is suitable for most cockpit environments. Your headset really holds the headstrap in place and the cinch is just there to keep the excess on the back of your head. If you will be doing aerobatics or flying in open cockpits, we suggest that you use the included Strong Cinch.
Changing from the Lightweight to the Strong Cinch is easy. First, remove the Lightweight Cinch, by pressing the button and sliding it off the strap. Then take a short length of safety wire, an un-bent paper clip or a wire twist-tie and push it through the opening of the Strong Cinch while pressing on the Cinch Button. Once it’s through, attach the webbing to the wire and then pull them both through the Cinch. Remove the wire and you are ready to go.
To install the temples, remove the headstrap by pressing the release tab on the inside of the hinges. Then the temples simply click into place.
Switching back to the headstrap uses the same steps. The release tab may be stiff the first couple of times you switch, but it will become easier with use.
NOTE: The inner side of the right hinge and strap have a raised ridge to help you quickly reattach the strap properly.
