Low bridge fit glasses are cut for a nose bridge that sits lower and flatter than the one most frames are designed around. They stay in place through three changes: a nose bridge that sits lower or nose pads that reach further out, less tilt in the lens, and a frame that is wider or shallower so it clears the cheeks. If your glasses slide, touch your cheekbones or rest on one spot, this is for you.
How to tell you need low bridge fit
Most frames are drawn around a nose that rises fairly high between the eyes. If yours starts lower or flatter, a standard frame has nothing to rest on, so it drops until it finds something, which is usually your cheeks. You do not need a measurement to spot this. The signs are consistent:
- They slide down. Not once, but all day, and you have stopped noticing that you push them back up.
- The bottom of the frame touches your cheeks. Smile and the frame lifts. Look down and it slides.
- Your lashes brush the lens. The frame is sitting too close to the eye because nothing is holding it forward.
- There is a mark or pressure on one spot of the nose rather than an even contact on both sides.
- They fog easily. The lens sits close to the face, so your breath reaches it.
Two or three of those together is a low bridge, whatever the shape of the rest of your face. This is common across East and Southeast Asian faces, which is why the same idea is often sold as Asian fit, but it is not exclusive to any ancestry. Plenty of people of every background have a lower bridge and have simply put up with sliding glasses for years.
Is Asian fit the same thing?
In practice, yes. Asian fit, low bridge fit and low nose bridge fit all describe frames built for the same set of facial proportions: a lower bridge, higher cheekbones and a flatter profile from the side. Brands pick the name that suits their marketing. MUJOSH designs every frame pattern for Asian fit as standard, so there is no separate low bridge line to search for. The fit is built into the whole range rather than bolted onto a few models.
What actually changes in the frame
Three things, and a good frame does all three rather than one.
The bridge sits lower, or the pads reach further
On an acetate frame with no separate nose pads, the bridge itself is cut deeper and its contact area is shaped to sit against a lower nose rather than perch on top of a higher one. On a metal or titanium frame, the nose pads sit on longer arms so they reach the sides of the nose instead of hovering above it. Either way, the frame has something to rest on.
Less tilt in the lens
Standard frames tilt the lens inwards at the bottom, which is called pantoscopic tilt. On a low bridge, that tilt is what drives the frame into the cheek. Low bridge frames reduce it so the lens sits more upright and clears the face.
A shallower or wider frame front
A frame that is slightly wider across the front, or slightly shallower from top to bottom, has more room before it meets the cheekbones. This is why some oversized shapes work surprisingly well on a low bridge, and why very deep, narrow frames often do not.
The measurements that matter, and how to read them
Every MUJOSH product page carries a SIZE AND FIT block. It lists the same five numbers you will find on the inside of any frame arm, and they tell you most of what you need before the frame arrives.
- Lens width. The width of one lens. This is mainly about how wide the frame looks on your face.
- Bridge. The distance between the two lenses at the nose. This is the number that matters most for a low bridge. Standard frames commonly run in the high teens to low twenties in millimetres. A lower figure means the lenses sit closer together and the frame rests further down the nose, which is usually what you want.
- Frame front. The total width across the front. Compare it to a frame you already own that fits.
- Temple length. The arm. Standard lengths are fairly universal and rarely the cause of a fit problem.
- Lens height. How tall the lens is. Combined with the bridge figure, this tells you whether the bottom edge will reach your cheek.
The quickest check is to take a frame you own that sits well, read the numbers off the inside of the arm, and compare the bridge and lens height to the product page. Match the bridge within a millimetre or two and keep the lens height similar and you will be close.
One honest note: MUJOSH is currently re-checking the figures printed on its product pages against the frames themselves, and this article will list model by model measurements once that is done. Until then, use the SIZE AND FIT block as your guide and the frame you already own as your reference.
Acetate, metal or titanium on a low bridge
The material changes how the frame handles a low bridge, and the right choice depends on what you want from the glasses.
Acetate frames have a fixed bridge cut into the material. When that bridge is shaped for a lower nose it is very comfortable, because there is nothing to press or pinch. When it is not, nothing can be done about it. So with acetate, the fit is decided by the pattern. This is where designing every pattern for Asian fit matters most, because you cannot adjust your way out of a badly cut acetate bridge. Look for a keyhole or saddle bridge shape, both of which spread the contact across the nose rather than concentrating it.
Metal frames carry separate nose pads on arms. The pads can be bent by an optician to sit further out or further down, which gives you some adjustment after purchase. The trade off is that pads concentrate weight on two small points, so a heavy metal frame can leave marks.
Titanium behaves like metal but weighs noticeably less, which matters on a low bridge because there is less nose to carry the weight. The lightest MUJOSH optical frames are titanium and Ultem, and the titanium glasses collection is the place to start if weight is the issue.
Sunglasses need one extra thing
Everything above applies to sunglasses, plus one more consideration: lens height. Sunglasses lenses are usually taller than optical lenses, and on a low bridge a tall lens is the first thing to reach your cheek. That is why oversized sunglasses in particular have a reputation for sliding. The fix is not to avoid oversized shapes but to pick ones cut with a lower bridge and enough width to clear the face, which is what the low bridge fit sunglasses collection groups together.
Shape wise, cat eye frames tend to do well because the upswept corner lifts the outer edge away from the cheekbone. Square and rectangle frames work when the lens height is moderate. Very round, very deep frames are the hardest to fit, though not impossible.
For sport, the sport sunglasses in the WAKE UP line take a different approach: a grip coating and silicone nose inserts hold the frame in place regardless of bridge height, and WAKE UP is the MUJOSH line built with adjustable nose pads so the fit can be set exactly.
What can be adjusted after purchase, and what cannot
An optician can do a surprising amount with a metal frame: bend the pad arms to move the pads out or down, adjust the temple bend behind the ear, and straighten a frame that has twisted. If a metal frame is close, an adjustment will usually get it there.
Acetate can be warmed and reshaped slightly at the temples, and the bridge can be very gently adjusted, but the bridge shape is essentially fixed. If an acetate frame slides because the bridge is cut for a higher nose, no amount of adjustment fixes that. Buy acetate frames that are cut correctly in the first place.
What cannot be fixed on any frame: a lens that is too tall for your face, and a frame front that is too narrow. Those are pattern decisions, so they are decided at purchase.

Frequently asked questions
What is low bridge fit?
A frame design for a nose bridge that sits lower or flatter than the one standard frames assume. The bridge or nose pads are positioned to rest on a lower nose, the lens tilt is reduced, and the frame is cut to clear the cheeks. The result is glasses that stay where you put them.
Is low bridge fit the same as Asian fit?
Yes, in practice. Both describe frames built for a lower bridge, higher cheekbones and a flatter facial profile. The names differ by brand, the design changes are the same.
Can anyone wear low bridge fit glasses?
Anyone whose glasses slide or sit on their cheeks, whatever their background. If you have a higher bridge, a low bridge frame may sit closer to your eyes than you like, but it will not be uncomfortable.
How do I measure my own bridge?
You do not need to. Read the numbers off the inside arm of a frame that already fits you well, and use the bridge and lens height figures as your reference when comparing product pages.
Do MUJOSH frames come in low bridge fit?
Every MUJOSH frame pattern is designed for Asian fit as standard. The two low bridge fit collections group the frames cut hardest for it.
Can I add prescription lenses?
Yes. Upload the prescription you already have from your optician and the lenses are fitted at the MUJOSH facility, in single vision, progressive or blue light. Frames that take a prescription are in eyeglasses and prescription sunglasses.
Which face shapes suit a low bridge frame?
Bridge height and face shape are separate questions. Low bridge is about how the frame sits on your nose, face shape is about which outline flatters you. The face shape guide covers the second question.
