Quick answer

Sunglasses get scratched from improper cleaning, rough storage, and contact with abrasive surfaces. Prevent it by using a microfiber cloth, storing in a hard case, and never wiping dry lenses.

Why scratches happen more than you think

Most scratches don't come from dramatic drops. They come from everyday habits: wiping lenses with a shirt, tossing sunglasses into a bag, or setting them lens-down on a table. Dust and grit act like sandpaper, so any wipe without rinsing can grind particles into the lens.

Lens coatings also matter. Anti-reflective and oleophobic coatings are soft by design, which makes them more susceptible to micro-scratches. Even premium frames like the Akoni Eris Two, with Japanese Galvanized Titanium construction, rely on the lens coating for clarity—so protecting that surface is key.

Trade-off: scratch-resistant vs. scratch-proof

Scratch-resistant coatings reduce the risk, but no lens is scratch-proof. Polycarbonate lenses are impact-resistant but softer than glass, so they scratch more easily. Glass lenses are harder but heavier and can shatter. For most people, a quality plastic lens with a scratch-resistant coating strikes the right balance.

If you already have deep scratches, there is no reliable DIY fix. Toothpaste and baking soda pastes are abrasive and can strip coatings, making the lens worse. Accept that replacement is the honest solution when vision is affected.

Diagnose and fix scratches step by step

  • Symptom: You notice fine lines or hazy areas on the lens, especially when light hits at an angle. Check both lenses under a bright light to confirm the scratches are on the surface, not inside.
  • Likely cause: Wiping dry lenses with a rough cloth, storing without a case, or placing lenses face down on abrasive surfaces. Change your cleaning and storage habits to prevent new scratches.
  • Corrective action: Rinse lenses with lukewarm water, apply a drop of mild dish soap, rub gently with fingertips, and dry with a clean microfiber cloth. Store in a hard case when not in use. Never use paper towels, tissues, or clothing to wipe lenses.
  • Stop or choose another option: If scratches affect your vision or cleaning doesn't remove them, stop trying home remedies. Contact your optician about lens replacement or a new pair. Do not use toothpaste or abrasive pastes; they will damage the coating further.

  • ERIS TWO: The Akoni Eris Two sunglasses are crafted from Japanese Galvanized Titanium, offering durability and style. A robust frame won't flex or twist, so the lenses stay aligned and are less likely to get scratched from frame movement during storage or handling.
