Glasses sliding down your nose? Try low-bridge fit.
If frames slip, rest on your cheeks, or sit too close to your eyelashes, the bridge and nose-pad design may be a better starting point than frame shape alone.
What is low-bridge fit?
Low-bridge fit is a frame design intended to improve how glasses sit on noses with a lower or less prominent bridge. Retailers may also use terms such as “alternative fit.” Labels and sizing differ by brand.
Three features to check
- Adjustable nose pads. They can help an optician fine-tune where the glasses rest.
- Bridge design. A frame's printed bridge number does not fully describe its three-dimensional fit.
- Frame width. Frames that are too wide can slide even when the nose pads are suitable.
How to tell it is the bridge
A few signs point to the bridge rather than the frame width: the glasses slide down within minutes, the bottom edge of the lenses rests on your cheeks, or the frames leave a mark on the sides of your nose. If the arms press on your temples instead, width is the likelier cause; compare it with the wide-faces guide and how to measure frame width.
Reading the bridge number
The middle number in a marking such as 52-18-140 is the bridge width, the gap between the two lenses in millimetres. Adult frames commonly run from about 14 to 24 mm. A smaller number is not always a better fit for a narrow nose, because the pads, the angle and the height of the bridge all matter. Two frames with the same printed bridge can sit very differently, which is why the number is only a starting point.
Things that can help
- Frames with adjustable pads. Metal pads on arms can be moved closer or further apart and re-angled by an optician. Many plastic frames have fixed pads moulded into the frame.
- Frames sold as low-bridge or alternative fit. These add built-in nose-pad height. Because each brand uses the label differently, check the photos and the store's description.
- Snug temple tips. An optician can adjust how the arms curve behind your ears, which keeps frames from sliding forward.
- A slightly smaller lens. Tall, heavy lenses pull a frame down. Compare lens height as well as lens width when a store lists it.
Try frames before buying
FitMyFace estimates face measurements and lets you compare frames from multiple retailers. Select the “glasses slide down my nose” option after scanning to prioritize suitable designs. This is a shopping aid, not a substitute for an optician's fitting or prescription measurements.

For prescription glasses, confirm pupillary distance and final fit with a qualified eye-care professional. A virtual fitting cannot establish comfort or bridge fit with certainty.
Questions
What does a low bridge mean?
It describes a nose with a lower or flatter bridge, where standard frames can rest on the cheeks. Frame makers also use "low-bridge fit" or "alternative fit" for frames designed with a different nose-pad shape.
Can an optician fix slipping glasses?
Often they can adjust the nose pads and the arms. Plastic frames with fixed pads have less room for adjustment than metal frames with pads on arms.
Does the bridge number tell me if a frame will fit?
Only roughly. It gives the gap between the lenses in millimetres, not the shape or height of the bridge. Photos of the frame on a face and an optician's check are more reliable.
Sizes are estimated from a photo, and the on-face drawing is approximate. It is not a substitute for an optician: let an optician confirm your prescription, pupillary distance and final fit. The ordinary glasses scan runs on your device. The optional AI previews (hair and glasses) send a photo to Cloudflare; your consent is the one "I agree" on the scan screen, and a switch on the results turns them off.
