I have been using pinhole glasses for a number of years. They are great for computer work, since they cut the glare, while making it easier to focus. When a couple of my "cheapies" broke or went missing, I decided to buy some new ones. The ones I ordered on this site were more costly than others I'd purchased before, but I was ready for the upgrade and ordered three pairs of Vistaview Pinhole Glasses. I am very pleased with the glasses. They are the most comfortable I've ever worn and the most effective. Even after only wearing them a couple of hours I feel the effect more than with others I've worn. I highly recommend this product and this website.
