If you’ve used typical non-prescription reading glasses (magnifiers) with plastic lens, you know how easily they are scratched. These have real glass lenses that don’t scratch easily. They’re not too heavy and the frame is strong. Comes with a decent case and cleaning cloth.First, I had a review here from a previous purchase a couple of years ago, but it's gone.The first pair I purchased were awesome. Real glass lenses, and you tell by the weight. They are easy to clean and stay clean longer than plastic.I am using 2 x lenses.I needed a second pair for work in case I forgot to take them with me in the morning. I looked everywhere for a real glass pair but could not find any, so I decided to order the same ones I had.It took a long time for these to arrive (at least a month), and I could tell as soon as I opened them that they were not glass, but plastic. They are way lighter than my other pair.On top of this, the "prescription" is not the same. My other pair are 2 x, and they work perfectly. This pair was supposed to be 2 x but when I use them, close things are still blurry (as in for reading), and things further away are not very blurry at all. It's the opposite way with my other pair. Reading or doing close work I have to do is very clear, but if I look in the distance everything is blurry. That's the way reading glasses should be if they are right for your eyes.I won't be purchasing these again. I can get just as low quality glasses in town here, there is no need to wait a month for quality like this.Nothing wrong with these glasses. They work well.I got the 2x version, and they are a little heavy, leaving red marks on my nose. I guess that's to be expected. Otherwise, very nice quality.Edit. These glasses have real glass lenses. I bought a different 3-pack from Amazon that was cheap, and the lenses are almost impossible to keep clean, and need special care to clean them well because the lenses are some type of plastic. I am now purchasing a second pair of these real glass glasses because they work so well.
