RE:
I help my grandpa purchase a progressive eyeglass from online website. Wearing it, he never feels tired. And, there is an important tip for buying progressive eyeglasses - it is recommended that you choose a larger frame type (height is not less than 28mm), which could help you get the more of the lens for the three prescriptions parts. It means that a bigger frame comes with a bigger lens. So that allowing your eyes to have more areas to get used to the three Rx powers. And, larger frame with the moveable nose pads is the best choice for progressive eyeglasses. Hope the above could help you.
