Do you know that glasses come in many sizes? There is little difference in the size of glasses between men and women, but there is a greater difference between children and adults.

There are three main digital measurements that your optometrist will use to make sure your glasses frame fits. These numbers represent the size of the temple of the frame (the handset or "arm" of the frame), the frame (the part that connects the nose to the lens), and the "eye" or lens size (the size of the actual lens).

Adult glasses.
For adults, these measurements may look like this: 52-19-150. The diameter of the glasses frame of this size is 52 mm, the diameter of the frame is 19 mm, and the length of the frame is 150 mm.

Although adults can have a variety of glasses size combinations, each part of the glasses size combination is within a standardized size range. The sizes of frame lenses range from 40mm to 60mm. (But some oversized styles or sunglasses may be bigger.). The bridge of a person's nose can vary in size from 14 mm to 24 mm, depending on the spacing of the eyes and the width of the nose. Although most frames have only a few temples of choice, standard temples can range in size from 120 to 150 mm.

If you buy the next glasses frame online, the general rule of thumb is like this. Select a new frame close to your current size. You can usually see this size in your glasses frame.). The optometrist recommends that you limit the size of the lens to less than 2 mm of your current frame (unless you deliberately choose a style that is too large), within 1 mm of the bridge size of your current frame, and within 5 mm of the temple size of your current frame.

For a child, these measurements can make a big difference. For obvious reasons, many of these measurements will be smaller. Children's lenses are about 40 to 50 millimeters in diameter. However, children's bridges may be similar to adult bridges, about 19mm. Children's temples are usually short in length, and many children's frames have temples of 135 mm in size. The size of a child's glasses frame looks more like these three numbers: 4819-135.
