Review on SIGVAN Progressive Multifocal Computer Blocking by Emma Jones

So if you work on computers all day or that long, you need this! No lie, this is a miracle device. I confess I was skeptical about the order and explained that if they didn't work I could return them. Well, to my surprise, these things are amazing! No more tired eyes and everything is so clear. I won't pretend to know the science of how and why they work, I just know they look clean and sharp. A literally essential product for people who spend a lot of time staring at a computer screen. Very inexpensive, so a good gift or surprise for someone. I almost forgot to mention that the frames are stylish and look like regular glasses so nobody knows these are not regular glasses. I will be buying more so I can keep some as a reserve at work in case a colleague picks up mine after they find out how great they are. Do yourself and your eyes a favor and buy a set or two.
