What is the Purpose of the Split Bridge Design?

The purpose of the split bridge is aesthetic. It is a bold design choice that draws attention to the nose and brow. The design is popular in vintage eyewear and sunglasses, as it adds depth and structure to the upper part of the frame.

Where Are Split Bridges Typically Used?

Split bridges are most commonly found on metal frames, where the thin metal can be easily shaped into two separate bars. They are also popular in navigator and aviator style frames, where the twin bars add a retro feel.

How Does the Split Bridge Affect Frame Strength?

The split bridge can sometimes be less strong than a standard, solid bridge if the attachment points are small. However, when made from durable materials like stainless steel, the dual bar construction can still provide adequate support and stability to the frame front.

Why Does Frame Design Matter for Contact Lens Users?

Since contact lenses disappear visually, backup glasses are often chosen to make a statement. The split bridge is a distinctive, fashionable design that provides a visually interesting contrast to the unencumbered look of contact lenses.

FAQs on Split Bridges

Does a split bridge make the frames heavier?

No, the amount of material used is minimal, and the frames remain lightweight.

Is the split bridge adjustable?

Adjustments are typically limited to the nose pads. The bridge itself should not be bent.

Is the split bridge the same as a saddle bridge?

No, a saddle bridge is a thick plastic bridge that curves smoothly over the nose for comfort. A split bridge is a thin, double-bar structure.

When to See Your Doctor

If your double-bridge or split-bridge frames feel unstable or cause a "pinching" sensation on the bridge of your nose, see your optician. Improper bridge tension can lead to skin irritation or headaches due to poor weight distribution across the nasal bone.
