Can Scratches On Lenses Be Removed Or Buffed Off ?
No, lenses cannot be "repaired" in the sense of removing scratches or damage while maintaining their original prescription. Here's why:
Prescription is in the Curve:
Eyeglass prescriptions are achieved by precisely surfacing and polishing the lens to a specific curvature. This curvature is what dictates the corrective power of the lens. Any attempt to polish out scratches will alter this curvature, effectively changing or eliminating the prescription.
The Depth of Scratches is Unknown:
You can't tell how deep a scratch is. Trying to buff it out would involve removing an unknown amount of material, which would invariably affect the lens's optical properties.
Anti-Reflective (AR) Coatings are Delicate:
AR coatings are baked onto the lens surface. They are susceptible to cracking, especially in high heat (like leaving glasses in a hot car in a tropical climate) or when exposed to harsh chemicals. Once an AR coating cracks, it cannot be repaired, and the lens will need to be replaced. Even wiping AR-coated lenses with improper materials or liquids can damage the coating.
Therefore, while you might physically remove a scratch by altering the lens, you would simultaneously ruin its prescribed optical properties, making it unusable for vision correction. For any significant scratch or damage, the only solution is to replace the lens.
Is it time to change your scratched lenses?
If your glasses are scratched, you know how frustrating it can be to see clearly. Unfortunately, lenses cannot be effectively repaired once scratched because it damages their precise prescription. The only way to restore your vision is to replace them.
