Review on Men and Women’s Half Frame Eyeglasses: Adjustable Reading Glasses with Spring Hinges for Individual Eye Power by Tracy Graham

This particular product is well thought out and finished. The lenses are easy to swap out and the package includes a wide range of diopters so you can make the right choice. However, the main disadvantage is that the lenses are really poor quality. You notice that as soon as you put on the glasses, because the picture is clear when you look straight on, but is heavily distorted when you look from the side. Because of this, I don't think it's possible to wear these glasses for too long. The manufacturer had to use high quality lenses, otherwise it's a waste of money.
