Cleaning
Daily Wipe: Quickly blow off any dust or dirt, then wipe the lenses carefully every time you put them on.
Use the Right Cloth: Always use the provided microfiber cloth or pouch. Do not use paper towels, tissues, or napkins, as the wood fibers in them act like sandpaper and will scratch the lenses.
Warm Soapy Water: For heavy smudges, warm soapy water is best. Standard washing-up liquid works well, provided it does not contain added moisturizers. Avoid chemical sprays unless they are specialist lens solutions.
Storage
Use the Case: Lenses are scratch-resistant, not scratch-proof. Always store them in a hard case or pouch when not in use.
Proper Placement: If you put your sunglasses down on a surface, ensure they are placed upside down with the arms wide open. Never place the lenses face down.
Long-term Storage: Thoroughly clean your frames and lenses before storing them for long periods (e.g., over winter) to prevent deterioration.
Additonal
Tighten Screws: Periodically check your frame screws with an optical screwdriver. Arms should open easily but not unfold under their own weight.
Keep out of direct sunlight and heat: While sunglass lenses and frames are designed to be in direct sunlight, doing so on a regular basis all day can deteriorate lenses causing visual defects. This effect is exaggerated if the lenses and frames are dirty or wet.
And if none of the tips above are working for you, don’t throw your favorite shades away. Simply fit a pair of high quality replacement lenses from Sunglass Fix and get that brand new feeling all over again.
