Lens CPR: Does This Lens Scratch Repair Kit Really Work?

Page content


The marketers of Lens CPR claim that it “fills microscopic scratches and imperfections on the surface of the lens, then dries to a hard protective surface.” However, if the many consumer complaints, regarding this product are anything to go by, you are better off cleaning your lenses with regular window cleaner.

The Lens CPR ads portray a product that is both easy to use and very effective. According to instructions from the manufacturer you first

need to:

  • Spray a thin layer of the cleaning solution over the entire surface of the lens.
  • Next, you will need to rinse and clean the lens.
  • Finally, apply the scratch remover and allow the product to dry. The manufacturer recommends that a blow dryer be used to improve the drying time. According to the ads the product is supposed to work instantly, but that couldn’t be farther from the truth.

It is very hard to find someone who has achieved a good result after using the product. In fact, the only thing that Lens CPR is good at doing is disappointing its customers. After using the product most consumers complain that the product left a cloudy residue that was labor intensive to remove to put it lightly.

Perhaps the product is just marketed to the wrong crowd; Lens CPR would really do well had it been marketed as an instance privacy solution; simply apply it to all the glass in your house and your neighbours will never be able to see you again. Yup, it is that bad!

Alternatives to Lens CPR: How to Clean your Glasses

results by simply using a compound to remove the antiglare coating, especially when the scratches aren’t severe. One solution that works well on plastic/polycarbonate lenses is Armour Etch. WARNING: do not use this product on glasses that are made from actual glass, as the product is really designed to frost glass and will render any real glass-based glasses useless.

However, you can still achieve amazing results with a $10 bottle of Armour Etch and a little time. Apply just enough of the solution to both sides of the glass and rub in the solution with a finger for a few minutes. After which, simply rinse the solution from the lens with warm water and use a non-abrasive cloth to wipe the lens clean. It is best if you keep the solution off the frame to achieve the best results.

On the other hand, if you have glasses that are made from real glass you are better off using toothpaste to buff the lens, and hopefully remove small scratches, than you would by using Lens CPR. If you fail to remove the scratches with any of these solutions you may be left with no option but to replace the glasses or the lens if you have taken a liking to the frame.


The Lens CPR glasses repair kit uses a so called space-age clear polymer that is claimed to fill microscopic scratches and imperfections on the lens’ surface then dries to a hard protective layer. But users complain of it leaving a cloudy residue that creates more mess the there was to start with.

An easy solution to scratched lenses is lens replacements, but that’s often a very expensive option that many are bent on avoiding. One product that is marketed as a solution to the scratched lens dilemma is Lens CPR, but as we have discussed, Lens CPR is far from being the fastest and easiest way to clean your scratched lenses.

In fact, consumers are more often than not left with glasses that are in a worst condition after using the product. Lens CPR simply falls short of what it promises. You are better trying to remove the scratches with toothpaste.
