Polishing Scratches from Plastic Optical Lenses: A Feasible Fix?

Every glasses wearer knows the annoyance of discovering a scratch on their lenses. Besides the aesthetic disturbance, these scratches can impact vision clarity. Plastic optical lenses, while popular for their lightweight nature, are prone to scratches. But can you polish these imperfections away? Let’s delve in.


1. The Reality of Polishing Plastic Lenses

While minor blemishes might be reduced, it’s crucial to note that attempting to polish away scratches can often cause more harm than good. Here’s why:

  • Lens Coatings: Many lenses come with special coatings like anti-glare, anti-scratch, or UV protection. Polishing can strip these away, diminishing lens quality.
  • Distorted Vision: Polishing may alter the lens’s shape, leading to vision distortion.

2. DIY Remedies: Proceed with Caution

Several DIY remedies circulate online, suggesting that common household items can diminish lens scratches. These include:

  • Baking soda and water paste
  • White toothpaste (non-gel)
  • Car wax

While these remedies might slightly reduce the visibility of scratches, they are not guaranteed solutions and carry risks. It’s essential to approach polishing with caution.

3. Professional Solutions

If scratches are bothersome, consider:

  • Optician’s Advice: Before taking any action, consult with your optician. They can offer guidance tailored to your lenses.
  • Lens Replacement: If the scratch is deep or affects vision, the safest solution might be lens replacement as polishing will not work. This ensures optimal vision quality and reduces the risk of eye strain.

4. Prevention is Better than Cure

Rather than addressing scratches after they occur, it’s more beneficial to prevent them altogether:

  • Protective Case: Always store glasses in a hard-shell case when not in use.
  • Microfiber Cloth: Clean lenses with a microfiber cloth, avoiding tissues or rough fabrics.
  • Avoid Harsh Environments: Be cautious in sandy, gritty, or dusty settings, as these can scratch lenses.
  • Consider Lens Coatings: Investing in an anti-scratch coating can extend the life of your lenses.


While the allure of a quick fix for scratched lenses is tempting, polishing plastic optical lenses is rarely the ideal solution. The potential damage and compromised vision make professional guidance the smarter route. By prioritizing prevention and valuing expert advice, you ensure that your lenses remain clear and your vision sharp.
