Pleasantly surprised at the quality of the lens and hinges.First the image was clearer than most of the dollar tree lens and of course these are continual bifocal. You have a clear image from top to bottom of the lens with changing focus. The image to the sides if for some reason you are looking sideways is slightly less clear but who does that?And we all know lower price glasses usually have cheap hinges that break. Well these things are strong metal and flexible so the side arms can actually extend past straight and flex right back. They seem like they will last.Happy I got them. Comes with three cases too but the cases don't have pocket clips but you have to leave one sidepiece out anyway for the glasses to fit so that sidepiece becomes your pocket hook I guess.Anyway, very happy.

I just received my glasses yesterday, so this review is for a first impression. I bought the +2.50 version. I use these glasses mainly for computer and electronics work. I have great far vision and not so good near vision. This means that my monitors are a bit fuzzy and my keyboard is very blurry. I wanted to stop using three different sets of glasses to see everything. I was using 1.0 for monitors, 1.5 for in between and 2.25 for electronics on my bench or seeing my keyboard.These glasses do indeed allow me to use one pair of glasses instead of constantly swapping or making do with what I was wearing. The only issue I have found is that there is a bit of a fish eye effect happening when I move my head. The glasses do not have the same focus horizontally. If you look to the side of the lens, the focus changes and is blurry. As long as I am looking straight at something, I can move my head up and down to get the best focus. Any time I move my head horizontally, it looks like the world is in a fishbowl and everything gets blurry. The image of my very dirty keyboard kind of show show the focus changes toward the edges of vision and the focus is best looked at directly on.These glasses work for what I am using them for, but I would not walk around wearing them.
