Why Do Safety Glasses Get Scratched?

Dust, sand and fine particles causing surface wear on safety glasses lenses

Dust, sand and fine particles causing surface wear on safety glasses lenses

Dust & Sand

Fine particles gradually wear lens surfaces

Frequent daily cleaning causing wear on standard safety glasses lens coatings

Daily Cleaning

Frequent wiping can damage ordinary coatings.

Accidental tool contact causing scratches on safety glasses lenses

Tool Contact

Accidental contact with tools causes scratches.

Safety glasses exposed to sparks and abrasive particles during industrial grinding

Harsh Environments

Grinding and industrial work accelerate lens wear.

Frequently Asked Questions

What Is Scratch-Resistant Lens Technology and How Does It Work?

Scratch-resistant lens technology is a protective hard coating applied to the surface of safety eyewear lenses to improve resistance against everyday abrasion, cleaning, dust, and fine particles.

· Polycarbonate lenses are naturally impact-resistant but softer than glass, making them more susceptible to surface scratches.

· A durable hard coating increases surface hardness while maintaining optical clarity and impact performance.

· Although no lens is completely scratch-proof, high-quality scratch-resistant coatings significantly reduce micro-abrasions, helping workers maintain clear vision, extend eyewear service life, and lower replacement costs.

· Korvion™ Scratch-Resistant Lens Technology is engineered to deliver long-lasting optical performance in demanding industrial environments.
