How to keep your sunglasses clean and scratch-free: tips for long-lasting lenses

Your sunglasses accompany you on every adventure: under the sun at the beach, on the road, or exploring the mountains. However, even the best lenses can lose their clarity over time if not properly cared for.

Keeping them clean and scratch-free not only improves your vision, but also extends the life of your sunglasses and preserves that crisp clarity that makes them special. Here are some practical tips to keep your lenses impeccable for years.

Clean your sunglasses with the care they deserve

A common mistake is cleaning sunglasses with a t-shirt or any ordinary towel. It seems harmless, yet these fabrics may contain dust particles that can scratch your lenses.

How should you clean them? Always use a soft microfiber cloth, like the one included in every Otis case. It’s designed to attach to the temple of your sunglasses, serving not only as a cleaning tool but also as extra protection.

Before cleaning, remove dust or sand by gently blowing or rinsing with lukewarm water. Then, dry the lenses with gentle, circular motions. If they are very dirty, use a specific eyewear cleaning solution—never household products or alcohol.

Always store them in their case

It may seem obvious, but most scratches occur when sunglasses are left loose in a backpack or on a hard surface. Always store them in a hard or semi-rigid case with a soft interior.

Otis reusable cases are designed specifically for this: protecting the lenses without taking up too much space, ensuring your sunglasses are ready for your next adventure.

Avoid high temperatures and chemicals

Extreme heat can damage both frames and lenses, especially if left in a car under the sun. Store them in a cool, dry place when not in use.

Also, avoid contact with lotions, sprays, or sunscreens, which can leave hard-to-clean residues or damage surface coatings. If they get dirty accidentally, clean them promptly with water and the appropriate cloth.

Handle them with care

Putting on or taking off your sunglasses with one hand can warp the frame over time. Always use both hands to maintain balance and avoid twisting. Never place sunglasses lens-down; always rest them on folded temples or in their case.

These small gestures may seem minor, but they make a big difference if you want to keep your sunglasses like new.

Choose scratch-resistant lenses from the start

The best way to keep your sunglasses pristine starts when you choose them. All Otis sunglasses feature thermally hardened mineral glass lenses, 12 times more scratch-resistant than plastic lenses.

This means not only will you enjoy superior optical clarity, but your sunglasses will continue looking new for much longer. Durability isn’t a promise—it’s part of Otis DNA.

Keep them ready for your next adventure

Proper maintenance takes only a few minutes but can extend the life of your sunglasses for years. Care for them, protect them, and clean them with the same attention you give to every adventure. Your sunglasses are more than an accessory: they’re an investment in clarity, style, and sustainability.

Choose quality, choose durability, choose a clearer view of the world. With well-maintained Otis sunglasses, your next adventures will look as crisp as the very first day.
