We bought these several years ago for our nature center program. They were fine at first but over time they started getting blurry and no amount of cleaning seemed to stop it. It may be unbreakable but if you can't see through it, what good is it?

We apologize that our product did not meet your expectations. Unfortunately, most transparent plastic products over time will become cloudy due to use, scratching, and oxidation of the plastic. I would like to suggest using olive oil to clean the lenses; if they are not badly scratched this should do the trick. You may also want to consider glass magnifiers which will not cloud and can be cleaned with an ordinary glass cleaner.
