First of all, get your eyes tested by professional optometrists. The opthalmic test enables you to get the prescription which is necessary for you to buy your eyewear. It is worth notice that: you'd better ask one professional person as an assistant when you choose reading glasses to assure the accuracy of your reading glasses with the centre of lenses coodinating with the centre of your eyes.

There are several issues to be considered for you to choose qualtiy glasses frames:

Good quality frame should be of high elasticity.
The bright and smooth coating is also important to quality frames.
The welding spots are also important in determining the frame quality: glossy, small and uniform ones are better.
The close-coupled frames are considered as quality frames.
The size and shape of two lenses should be totally the same, and the nosepiece should be symmetrical.
When the old people buy reading glasses, it is OK to choose common lense or bifocals. The key is that whether the transmission of light is good. However, the lenses of old citizens become harder and harder. The accommodation power and organization in eyes are also feeble and old. To relieve the eyesight and make it convenient to view things located near and far away, it is suggested to buy bifocals; progressive lenses will be better. They are more helpful in protecting eyes.
