What Does 55mm Mean in Sunglasses?

You may have noticed that the arms and bridge of your glasses have numbers on them. These numbers indicate the model, colour code, and measurements of the frame. For example, 55mm is the width of the lens, 18mm is the width of the bridge, and 145mm is the length of the arm. Keeping these measurements in mind will make your purchase easier.

Temple Size

The first step in choosing the correct pair of sunglasses is to measure the face and temple length. This way, you will be able to identify what size frame to buy. For example, if your face is 130mm in width, you will need to get a pair of sunglasses that have a 55mm temple length. If your face is more than 140mm in width, you should get a pair of sunglasses that are 56mm or 58mm in temple length.

Typically, sunglasses and eyeglasses will have the length and width of the frame printed on the inside of the left temple. There will be three numbers listed: the first number refers to the width of the bridge, the second number refers to the width of the arm, and the third number refers to the length of the temple. You will also find the diameter of the lens and the bridge width printed on the front of the sunglasses.

Eye Size

Sunglasses, also known as eyeglasses, have a size measurement on the inside of the left temple. The measurement is normally in millimeters. The two lowest numbers are the Bridge Size and Lens Width, while the second and third numbers are the length and width of the frame arms. Finally, the height and width of the lenses are usually noted as well.

This measurement is useful for sunglasses with wide frames. The lens width measures the horizontal diameter of the lens at its widest point. For example, the lens size of the Ray-Ban New Wayfarer Sunglasses is 55mm. Whether your glasses fit properly will depend on the lens size.

Vertical Measurement

If you are buying sunglasses, it is important to note that the vertical measurement of sunglasses is often not helpful. Normally, this measurement is from the bottom of the lens up to the top of the frame. If you are buying sunglasses without prescription lenses, this measurement is not necessary. Typically, this measurement is between 32 and 38 millimeters.

You should also check the width of the frame before you buy them. You should make sure that the frames fit your face and that the lenses are centered on your face.

Frame Thickness

When you buy sunglasses, it is important to remember that the frame thickness of sunglasses is important in order to fit your face. It should be able to support the lenses. You can also check the width by measuring the lens and the bridge. If the width is within two millimeters of your face, it should fit.

The bridge is a piece of plastic or metal that joins the two lenses together. Its width is usually between 14 to 24 millimeters. Next, the length of the temple is important to keep the sunglasses on your face. The length should extend to the part of your ear that hooks over the bridge. The height of the lens is also important. The height of the lens varies between 32 and 38 millimeters.

Frame Size

There are three main measurements that determine the frame size of sunglasses, the bridge width, the height of the lenses, and the temple width. The bridge width refers to the width of the bridge, which sits over the nose, and the temple length refers to the length of the 'arm' that holds the sunglasses on the face. The lens height is the height of the lens vertically from the frame, and varies from brand to brand. A typical lens height is between 32 and 38 millimetres.

In order to choose the right frame size, first determine your face size. If you have a small face, the frame width should be less than 130mm. A medium face should be between 131mm and 141mm in width. A large face should have a frame width at least 2mm larger than the face width.
