When choosing reading glasses one of the questions that usually comes up is whether to go with a plastic or metal frame? The preference of metal or plastic reading glasses basically comes down to one thing and that is comfort and that's personal.
Reading Glasses: Metal vs. Plastic
Certain facial characteristics such as a wide or narrow nose, usually is best fit with a metal frame where flexible nose pads can be adjusted to fit the contours of your nose more easily.
Knowing the frame style that suits you best establishes the foundation for style that’s timeless and also wears comfortably. Variations of established frame shapes do emerge season after season, but your most flattering look can be had by pinpointing the style that compliments your facial characteristics and then going from there.
