Have you heard of the term catfish? …not talking about the ugly-looking fish with whiskers. A catfish is a pretender -someone who pretends to be someone they’re not. A catfish on a dating or social media site is someone who creates a false identity, mainly to pursue a romantic ‘relationship’. The term “to be catfished” in the retail world, means to be fooled by claims that are not real. In today’s world what is claimed is not always what you truly get in a product.
The world of fits over sunglasses is filled with catfish so we decided to help you sift through the bunch and get to the real deal. Many ‘fits over’ sunglass companies claim to be original fits overs, to have polarized lenses, to have 100% UVA/UVB protection or to have scratch-resistant lenses, but they simply aren’t and don’t. We did some research and even tested fits over sunglasses and this is what we found: The first company in the U.S. to sell fits overs was Solar Shield back in 1979. The lab tests confirmed that, indeed, Solar Shield fitsover sunglass and clipon lenses, gray and amber, are polarized which means the lenses block glare, they have 100% UVA/UVB protection which means the lenses protect your eyes from light waves up to 400 nanometers (UV400), and Solar Shield lenses are scratch-resistant, which means the lenses have a hard coat that makes them impervious to scratching from simple things like placing your fits overs on the table, dashboard or even dropping them at home.
If you want to test a pair of fits overs on your own, here are a few suggestions of what you can do. Test the sunglasses for polarization by looking at a computer screen when the computer is turned on. Computer screens use the same polarization technology used to polarize lenses. Put on the fits over sunglasses in question and tilt your head left and right while looking directly at the screen. If the screen gets darker and lighter as you tilt your head, your glasses are polarized. If you don’t have a computer handy, look at a reflective surface under the sun like water, a mirror, the pavement or other, while wearing the sunglasses. If the fits over sunglasses are truly polarized the glare from the surfaces will be greatly diminished if not eliminated.
If you want to know if your sunglasses or fitovers truly offer 100% UVA/UVB protection you will need the help of an optometrist. Most optometrists can test the UV protection of your sunglasses for free in a matter of seconds.
To find out whether fitovers or sunglass lenses are scratch-resistant there’s not much you can do. No lenses are scratch-proof but scratch-resistant lenses shouldn’t scratch if you happen to clean them with a paper towel or drop them on the floor. You probably won’t want to test this because chances are the retailer will make you buy the sunglasses if you damage them.
