Types of Scratches & Their Underlying Causes

1. Surface Scratches

  • Surface scratches often result from minor incidents like wiping glasses with a dirty cloth or improper cleaning techniques.
  • These scratches are superficial, affecting the outer layer of the lens without penetrating deeply.

2. Deep Scratches

  • Impact from sharp objects, drops, or prolonged wear without proper care can lead to deep scratches.
  • They penetrate the lens, potentially affecting vision and requiring more extensive repair measures.

3. Abrasive Scratches

  • Using harsh cleaning materials or abrasive substances on lenses can cause abrasive scratches.
  • These scratches occur due to the friction of abrasive particles against the lens, resulting in visible marks.

4. Coating Scratches

  • Improper handling or cleaning can damage the protective coatings applied to lenses.
  • Coating scratches affect the protective layers on the lens, compromising their effectiveness and appearance.

5. Hairline Scratches

  • Microscopic particles, repeated cleaning with dirty cloths, or improper storage can cause hairline scratches.
  • These tiny scratches may not significantly impact vision but can accumulate over time, affecting clarity.
