Why is peeling happening to my sunglass lenses?

Unraveling the Mystery: Why Your Sunglass Lenses Are Peeling

If you’ve noticed the lenses of your sunglasses starting to peel, you’re not alone. This common issue can be both puzzling and frustrating, especially if your sunglasses are a cherished accessory. Let’s explore why sunglass lenses peel and what can be done about it.


1. Understanding the Peeling Process

  • Coating Deterioration: Often, the peeling in sunglass lenses is due to the deterioration of the lens coating. Many sunglasses have additional layers for UV protection, anti-glare, or scratch resistance. Over time, these layers can start to peel off.

2. Causes of Peeling

  • Exposure to Elements: Regular exposure to sunlight, heat, and moisture can break down the lens coatings. For example, leaving sunglasses in a hot car can accelerate this process.
  • Chemical Reactions: Certain chemicals, like those in sunscreen or cosmetics, can react with the lens coatings, causing them to degrade.
  • Wear and Tear: Normal wear and tear, including cleaning the lenses with harsh materials or solutions, can also lead to peeling.

3. Quality of Sunglasses

  • Material and Manufacturing: The quality of the materials used and the manufacturing process can impact how resistant the lenses are to peeling. Higher quality sunglasses tend to have more durable coatings.

4. Preventing Lens Peeling

  • Proper Storage: Store your sunglasses in a protective case to shield them from heat and moisture when not in use.
  • Gentle Cleaning: Clean the lenses with a soft, microfiber cloth and avoid harsh chemicals. Use lens cleaning solutions specifically designed for sunglasses.
  • Careful Handling: Handle your sunglasses gently to avoid scratches or damage to the lens surface.

5. Addressing the Issue

  • Professional Advice: If your sunglasses are still under warranty, contact the manufacturer for advice about the peeling. They may offer a replacement or repair.
  • Replacement Lenses: For high-quality frames, consider replacing the lenses rather than buying a new pair of sunglasses.


Peeling sunglass lenses can be a result of various factors, including environmental exposure, chemical reactions, and the quality of the lenses. By understanding these causes and practicing proper sunglass care, you can extend the life of your lenses and enjoy clear, protected vision on sunny days.
