Your spectacles should be centered in your face, no higher than your brows. Your frames should be the same width as your face at the temples, with enough space on the sides to avoid digging in or leaving marks. A good pair of glasses will give you a sense of visual equilibrium. They shouldn't make you feel like you need reading glasses when you get up close to the screen. If you wear your glasses all day long, it's important that they fit properly. If they are too tight around your ears or nose, this can cause headaches and even damage your hearing. Be sure to take off your glasses every night and put them away carefully each morning so they don't get scratched or damaged in any other way. Glasses stores often have specialists who can help you find the correct size frame for your face. You may want to ask one of these experts how wide their recommended range is for each model number. This will help ensure you don't buy an old frame that's been stretched out by previous owners. You should also check the label on your current glasses case to see if there is any information about sizing. Some cases only fit certain types of glasses, so be sure to check before you buy another case. Finally, try on several pairs of glasses with the same type of frame from different brands. This will help you find ones that fit properly but still look like a part of you.
