Depending on the severity, replacing the lenses may be the most practical option.
This is especially important if the glasses are prescription lenses and the scratch is directly in your line of sight.
The Best Way to Prevent Scratches
Prevention is much easier than trying to repair damaged lenses.
Whenever you aren’t wearing your glasses, keep them inside a protective case.
When cleaning them, first remove dust and particles with water rather than immediately rubbing the dry lens.
And never place the lenses face-down on a table.
A few seconds of care can help extend the life of your glasses considerably.
The Bottom Line
The toothpaste trick is an old household remedy that claims to make minor scratches less visible, but it isn’t a good choice for most modern prescription eyeglass lenses because its abrasiveness can damage protective coatings.
If your glasses are scratched, don’t immediately reach for toothpaste.
Clean them properly, inspect the damage, and ask an optician about the safest solution if the scratch affects your vision.
Sometimes, the cheapest-looking repair can end up costing more than simply getting the lenses professionally checked.
