To clean your frame and lenses, use the cleaning cloth provided. While holding your frame by the bridge (the central part of the frame, between the two lenses), rub the frame and lenses with the cleaning cloth, applying light pressure to restore their shine.
Your frames are built to last, provided you adopt a few good habits. Do not expose them to heat or moisture, and store them in their case. Avoid leaving them in a car in direct sunlight.
Step 1. Rinse with cold water
Rinse with cold water to remove the sand or dust. Never rub before this rinse, as you risk scratching the lenses (do not use hot water, as it could damage the lens coatings and the frame itself).
Step 2. Remove grease using mild soap
Once the sand or dust has been removed, place a drop of mild pH-neutral soap on both sides of each lens and lather it to degrease the frame.
Step 3. Rinse again
Rinse again with cold water until all the soap is gone.
Step 4. Dry without rubbing
Dry with a tissue, without rubbing. Pay particular attention to drying the hinges.
Step 5. Restore the shine
To finish, restore the shine by gently rubbing with the cleaning cloth, holding the frame by the bridge.
Tip 1. Acetate: a material that deserves attention
Cellulose acetate is prized for the richness of its colors and patterns, but it is also the most sensitive material used in eyewear. Unlike titanium, it reacts to its environment: prolonged exposure to strong heat can deform it, while repeated contact with everyday solvents — perfume, sunscreen, makeup, alcohol-based cleaning products — gradually attacks its surface and can dull its shine. This is the price to pay for the depth of color and texture unique to acetate, but it calls for more regular attention than a titanium frame — more frequent cleaning, and storage away from heat.
Tip 2. Restoring acetate's shine
Over time, acetate develops a natural surface oxidation — a light, pale haze that appears mostly on darker frames. This is perfectly normal and does not indicate any damage. To restore the original shine, see your optician, who can advise you on the right polishing treatment.
Tip 3. Titanium frames
Titanium requires very little care. It is naturally corrosion-resistant, lightweight and hypoallergenic, which explains how well it holds up to daily contact with skin and perspiration.
Wipe the frame regularly with the cleaning cloth. Alcohol-based cleaners, makeup and perfume do not harm raw titanium, but they can attack the plating applied on top, which gives the frame its color (gold, for example). Although titanium is remarkably wear-resistant, it is not immune to mechanical stress: a slightly bent frame may look easy to straighten by hand, but bending titanium without the right tools fatigues the metal invisibly. It is best to let your optician make the adjustment, with the right technique and the right tools.
Tip 4. Hinges: the hardest-working component
The hinges are the most heavily used part of the frame. They are small assemblies of screws and moving parts under constant tension every time the temples are opened and closed — dozens of times a day, thousands of times a year — so wear builds up there long before it becomes visible anywhere else on the frame.
A screw loosening after several months of use is normal; it is not a defect. But if left as it is, the temple starts to develop play, which accelerates hinge wear. Have it tightened by your optician with a proper optician's screwdriver: an ill-fitting tip can damage the screw head. Keep the hinge dry, as moisture and residue that seep in will stiffen the joint over time.
Finally, if a hinge starts to feel gritty or stiff, ask your optician to oil the joint to prevent excessive strain on the hinge.
Always place your glasses with the lenses facing up, to avoid micro-scratches. The cleaning cloth provided is all you need for everyday care; for a more thorough clean, use our 5-step cleaning method described in the Daily Care section.
The lenses of our sunglasses feature an inner anti-reflective coating to improve contrast and strengthen your protection against UV rays. This coating is sensitive to heat: this is why you should never use hot water to clean your glasses, at the risk of permanently damaging the coating.
The same goes for your prescription frames: the lenses you have chosen are very likely to have an anti-reflective coating with the same properties as our sun lenses. Here too, avoid exposing them to heat.
When you are not wearing your glasses, the hard case provided remains their best protection: it shields them from knocks, dust and scratches. Always dry the frame before putting it away, as moisture trapped inside the case can stiffen the hinges over time. If you need to set your glasses down for a moment, place them with the lenses facing up — never flat on the lenses. Finally, choose a dry spot, away from heat and direct sunlight — never in a car in summer or near a heat source.
