Scratched Glasses Lenses: Can They Be Repaired or Do They Need Replacing?

Scratched Glasses Lenses: Can They Be Repaired or Do They Need Replacing?

Few things are more frustrating than scratching the lenses in a favourite pair of glasses. The frames may be perfectly good, your prescription may still be correct, but suddenly there's a scratch sitting right where you don't want it.

So, can scratched glasses lenses actually be repaired?

Unfortunately, in most cases, the answer is no — but that doesn't mean you need to buy a new pair of glasses.

Why can't scratches simply be polished out?

It's tempting to think that a scratch in a spectacle lens could simply be polished away, particularly when there are plenty of supposed DIY remedies online.

We wouldn't recommend it.

Prescription lenses are manufactured with precisely controlled optical surfaces. Modern lenses may also have several specialist coatings, including hard coatings and anti-reflection treatments.

Trying to polish away a scratch means removing material from the lens. Apart from potentially damaging the coatings, this can affect the optical surface of the lens itself.

Household remedies such as toothpaste, baking soda or abrasive polishes aren't something we'd recommend using on prescription lenses either.

What about scratched lens coatings?

Sometimes what appears to be a scratch may actually be damage to one of the lens coatings.

Anti-reflection coatings in particular can become damaged through age, heat, chemicals or abrasion. Once a coating has deteriorated, it generally isn't practical to remove it and reapply a new coating to an existing prescription lens.

Again, replacement is usually the sensible solution.

But you don't necessarily need new glasses

This is the bit many glasses wearers don't realise.

If your frames are still in good condition, you can usually keep them and replace only the lenses.

The old lenses are removed and completely new lenses are manufactured to fit your existing frames.

This process is known as glasses reglazing.

So if you've scratched the lenses in an expensive designer frame, a favourite pair you've owned for years or simply a pair that fits perfectly, there's often no reason to throw the frames away.

Can I use my existing prescription?

If your prescription is still current and suitable to use, new lenses can normally be made to that prescription.

If you're due an eye examination, however, it makes sense to have your eyes tested first. You can then have the replacement lenses manufactured to your latest prescription rather than replacing scratched lenses only to discover shortly afterwards that your prescription has changed.

Can I upgrade the lenses while they're being replaced?

Absolutely.

Replacing scratched lenses is also an opportunity to change the lens specification if you wish.

Depending on your prescription and frame, you could choose thinner lenses, anti-reflection coatings, Transitions light-adaptive lenses, tinted or polarised lenses, or change to a different lens design altogether.

You aren't restricted to replacing the scratched lenses with exactly the same type.

Are all frames suitable for new lenses?

Most good-quality frames can be reglazed, but the condition of the frame is important.

Older frames can occasionally become brittle or weakened with age, while damaged hinges, cracks or other structural problems may make a frame unsuitable.

At Reglaze Glasses Direct, we assess frames before fitting the new lenses and will contact you if we have any concerns.

We also regularly work with more specialist frames, including rimless and designer designs.

Is replacing scratched lenses worth it?

If you still like your frames, very often it is.

Good-quality frames can last considerably longer than the lenses fitted into them. Replacing only the lenses can therefore be a much more economical way of updating your glasses.

There's an environmental benefit too. Keeping a perfectly usable frame in service rather than replacing the entire pair reduces unnecessary waste.

Scratched lenses? Don't throw away your favourite frames.

A scratch doesn't necessarily mean the end of your glasses.

While scratched prescription lenses generally can't be safely polished back to their original condition, in most cases they can simply be replaced.

That's exactly what reglazing is for.
