4. Avoid Metal Polishes
Some online guides suggest metal polishes like Brasso. Avoid this! They are far too strong and can permanently damage lenses, causing fogginess or etching.
5. Prevention and Care
Since repairing lenses fully is often impossible, preventing scratches is key:
Use a Hard Case: Always store glasses in a protective case.
Clean Properly: Use lens spray and a microfiber cloth. Avoid paper towels, napkins, or clothing.
Lenses Up: Place frames on surfaces with lenses facing up.
Upgrades: Consider premium scratch-resistant coatings for new lenses.
