If you wear glasses, you may have noticed that there are different types of bridges for glasses. The bridge is the part of the frame that rests on your nose and connects the two lenses. The bridge can affect the comfort, fit and style of your glasses, so it is important to know what type of bridge suits your face shape and personal preference.

What is bridge width?

Eyewear frame measurements contain three numbers in a format like 55-20-145. The middle number is the bridge width. It shows the distance between the lenses and ranges from 14 to 24. If your nose is narrow or your eyes are close, you’ll need a lower number, such as 14mm to 18mm. If your nose is wider or your eyes are positioned further apart, look for 18mm or higher.

Here are some common types of bridges for glasses:

Adjustable Nose Pads

This is a curved piece of plastic that spans across your nose and follows its contour. It is typically found on plastic frames, especially full-rimmed ones. A saddle bridge distributes the weight of the glasses evenly across your nose, which can make it more comfortable and stable. A saddle bridge also requires less maintenance than adjustable nose pads, as it has fewer moving parts.

Saddle Bridge

This is a curved piece of plastic that spans across your nose and follows its contour. It is typically found on plastic frames, especially full-rimmed ones. A saddle bridge distributes the weight of the glasses evenly across your nose, which can make it more comfortable and stable. Moreover, a saddle bridge creates a contemporary look and typically fits snugly around the nose with minimal gaps at the top, making it a low-maintenance option compared to nose pads that require frequent adjustments due to their more intricate design.

Keyhole Bridge

The keyhole bridge is a unique and stylish design element that is commonly found on plastic frames, especially vintage or retro styles. It is shaped like an old-fashioned keyhole, with a wider top and a narrower bottom, and rests on the sides of the nose instead of the top. This placement can be particularly beneficial for individuals with wider noses or low bridges, as it eliminates pressure from the top of the nose. Additionally, the keyhole bridge allows for greater flexibility in the fit, as it can be easily adjusted to slide up or down the nose depending on personal preference. However, it's worth noting that the keyhole shape may create an illusion of a longer and wider nose, which can affect the eye-nose geometry, especially if the frame color is dark.

Double Bridge

The double bridge of glasses is a stylish and functional feature that adds a touch of sophistication to any eyewear. It refers to the extra metal bar that connects the two rims above the nose bridge, creating a distinctive look. The double bridge of glasses can also provide more stability and durability to the frame, as well as enhance the comfort and fit of the wearer. Whether you prefer a classic aviator style or a modern geometric shape, the double bridge of glasses can elevate your appearance and personality.

Low Bridge Fit

Glasses with a low bridge fit are designed to provide a comfortable and secure fit for individuals with low nose bridges, wide faces, or high cheekbones. These frames feature a lower bridge, deeper nose pads, and longer temples, which allow the glasses to sit higher on the nose without slipping or pinching. The lower bridge and deeper nose pads offer a better grip, while the longer temples help reduce tension on the nose and cheeks, ensuring proper adjustment behind the ears. With these features, low bridge fit frames can provide a solution for those who struggle to find glasses that fit comfortably and securely.
