When selecting your eyeglasses, it is important that you make sure the eyeglass frames you choose will be comfortable and fit you well.
You have to make sure that the temples do not dig into the side of your head and that the frames are wide enough for your face. The edge of the frames should protrude slightly beyond your face so that the temples do not touch your head as they extend back to your ears.
Also, you have to make sure the temples are long enough. There are many styles in a variety of temple lengths. The curve at the end of the temple should extend over the ear without pressing down upon it. The optician can reshape and adjust the curve at the end of the temple, but he cannot make the temples shorter or longer, that is why it is important that you select the best length.
As well, you have to check the nosepiece for comfort and fit. Many glasses have adjustable silicone nose pads that allow your optician to fine-tune the fit. For frames without adjustable nose pads, make sure the fit is secure without pinching the bridge of your nose.
When you try on the frames, move your head up and down, bend over and pick up something from the floor and see how well your glasses stay in place. With the properly adjusted nose pads and temples, your glasses should stay in place without pressing on your face.
If you already have a pair of frames that you would like to purchase again or even find a pair of frames similar to yours, you can quickly identify the designer name, model number, and frame size by simply looking on the inside of your eyeglass temples (arm pieces).
Below is a quick guide to helping you identify the size of your eyeglasses.
Components of Frame Sizes:
Eye Size: Measured from outermost edges of lenses horizontally (approximately 40 mil to 62 mil)
Bridge Size: The distance between lenses (approximately 14 mil to 24 mil)
Temple Length: Length of temple piece - also know as the arm piece or ear piece (approximately 120 mil to 150 mil)
