How Can You Determine if a Scratch on Your Glasses Lens is Deep?

To determine if a scratch on your glasses lens is deep, you can use several assessment techniques that evaluate the scratch’s visibility, feel, and impact on vision.

Visual Inspection: Examine the scratch under good lighting. If the scratch reflects light and appears deep, it likely penetrates the lens surface.
Fingernail Test: Gently run your fingernail over the scratch. If your nail catches in the scratch, it indicates a deeper damage compared to a scratch that feels smooth.
Clarity Check: Wear your glasses and assess your vision. A significant impact on your clarity indicates that the scratch may be deep.
Water Test: Place a drop of water on the lens. A deep scratch will disrupt the water’s surface tension, making it spread unevenly, while a shallow scratch will have less noticeable effects.
Anti-Reflective Coating (if applicable): If your glasses have an anti-reflective coating, deep scratches can damage this layer. Inspect the scratch for signs of peeling or chips around the area.
