Comfort comes from fit, not just style
Most discomfort with glasses comes from a handful of fit problems: a bridge that does not match the nose, a frame that is too narrow or too wide, arms that are the wrong length, or more weight than the nose can comfortably carry. Style matters too, of course, and the good news is that most shapes come in more than one size. Start with fit, then choose the look you love within the sizes that work.
Five fit cues to check in the mirror
1. The bridge
The bridge is where the frame meets your nose, and it carries most of the weight. It should sit flat against both sides of your nose with no gaps and no pinching. Red marks after a few minutes mean the weight is concentrated in too small an area. If the frame rests on your cheeks when you smile, it is sitting too low.
Frames with adjustable nose pads can be shaped to fit low, narrow or uneven bridges. Acetate frames with a fixed bridge need to match your nose more closely, though some styles have a lower or wider bridge fit for that reason.
2. Width
The front of the frame should be close to the width of your face. A frame that is too narrow presses on your temples and the arms bow outward. One that is too wide slides and can make your eyes look off-center. Look straight into a mirror: your eyes should sit roughly in the middle of each lens, horizontally.
3. Temple length and bend
The arms should run straight back without pressing into the sides of your head, then bend down just behind the top of your ears. If they bend too early, they push the frame forward. If they bend too late, the frame slides. An optician adjusts this bend to your ears.
4. Weight and balance
Thick acetate and large lenses add weight. So do strong prescriptions. Titanium and thin metal frames are lighter, but what matters most is how the weight is distributed between your nose and ears. A balanced frame does not tip forward when you look down.
5. Level and stable
The frame should sit level, not higher on one side. Shake your head gently and look down at the floor. A well-fitted frame stays put.
Quick try-on checklist
- Bridge sits flat on your nose, no gaps or pinching
- Frame does not rest on your cheeks when you smile
- Eyes sit near the center of each lens
- Arms do not press into the sides of your head
- Arms bend just behind your ears
- Frame stays in place when you look down
- No pressure points after wearing it for a few minutes
If your prescription is strong
Strong prescriptions make lens shape and size matter more:
- Nearsighted (minus) prescriptions have thicker edges. Smaller lenses, and frames that place your eyes near the lens center, keep edges thinner.
- Farsighted (plus) prescriptions are thicker in the center and can magnify your eyes. Smaller, rounder shapes keep lenses lighter.
- High-index materials make lenses thinner and lighter for stronger prescriptions. Ask about them when you choose a frame.
- Full-rim frames hide thick edges better than rimless or semi-rimless styles.
If you wear progressives or bifocals
Multifocal lenses need enough vertical room for each viewing zone, so very shallow frames can crowd the reading area. Look for a frame with enough lens height, and expect the optician to measure where your pupils sit in the frame you choose. Our guide to progressive lenses explains why.
Trying frames on with your current pair in mind
Your current glasses are a useful starting point. If they feel right, the three numbers printed inside the arm give a size to start from. If they bother you, note where: the nose, behind the ears, or at the temples. That tells the optician what to change. Our guide to frame sizes shows how to read those numbers.
Many frame styles, designer ones included, are made in more than one size. Whether you are drawn to Prada, Ray-Ban, Burberry or Coach, asking for the size that fits your face is part of choosing the frame.
Next step
Browse frames and collections, then come in to try styles on. An optician can check the fit, adjust the frame, and take measurements for your lenses.
