Sunglasses and eye frames come in all sizes and suit a variety of face shapes. If you look inside your existing frames or sunglasses you will probably see two or three numbers.
The first number (normally between 48 and 58) is the lens width. The bigger the number, the bigger the lens. The second number (between 15 and 25) is the width between the lenses. The bigger the number, the wider the distance. The last number (between 135 and 150) is the temple length. If you have ever had problems with glasses not reaching over your ears, you should look for glasses with a temple length of at least 145mm.
