Glasses that hurt behind your ears are almost always caused by temples (the arms of your glasses) that curve too tightly, sit too low, or press too hard against the bone just behind your ear. The good news: this is one of the easiest eyewear problems to fix at home, and it rarely requires new frames. A few small bends in the right spot can eliminate the pain entirely.
Why This Spot Hurts So Much
The area behind your ear isn’t just skin over bone. The bony bump you can feel there is called the mastoid process, and it sits at the intersection of several sensitive nerves, including the greater auricular nerve and the lesser occipital nerve. When a glasses temple presses against this zone for hours at a time, those nerves get compressed, producing soreness, headaches, or even a burning sensation that radiates up the side of your head.
Because there’s very little soft tissue padding the mastoid process, even mild pressure becomes painful over a full day of wear. That’s why glasses can feel fine in the morning and agonizing by evening.
Identify the Specific Problem First
Before you start bending anything, put your glasses on and pay attention to exactly where and how they hurt. The fix depends on the cause.
- Pain directly on the bone behind your ear: The temple tips curve inward too aggressively, digging into the mastoid. You need to open up that curve.
- Pain on top of your ear: The temples are angled too steeply downward, pressing the ear between the frame and your skull. You need to flatten the bend slightly.
- Squeezing or pressure on both sides: The temples are too narrow overall, creating lateral pressure against your head. You need to widen the temple spread.
- Pain that worsens as the day goes on: The temples may be slightly too short, pulling the curve point forward so it sits on the wrong part of your ear.
Adjusting Plastic (Acetate) Frames
Plastic frames will snap if you try to bend them cold. You need to heat them first to make them pliable. Use a hair dryer on its warm setting, held a few inches from the temple tip, for about 30 seconds. Focus the heat on the curved section that hooks behind your ear. The plastic should feel warm and slightly flexible when you test it with gentle pressure. If it still feels rigid, give it another 10 to 15 seconds of heat.
Once the plastic is warm, make your adjustment slowly. If the temples are digging into the bone behind your ear, gently bend the curved end outward to open up the hook. You’re aiming for a curve that follows the natural contour of your ear without pressing inward. Move in small increments, try the glasses on, and repeat. Overcorrecting will make them slide off your face.
If the temples are too tight overall, creating a squeezing sensation, heat the section near the hinge where the temple meets the front of the frame. Gently push the temple outward at that point to widen the spread. Again, go slowly. A millimeter or two on each side makes a noticeable difference.
Let the plastic cool completely before wearing the glasses. The material sets into its new shape as it cools, so hold it in position for 20 to 30 seconds or set it down on a flat surface.
Adjusting Metal Frames
Metal temples bend without heat, but they’re less forgiving if you bend them in the wrong spot. Use your fingers for gentle adjustments. For more precise work, small needle-nose pliers are helpful. Wrap the jaws in tape, a thin cloth, or a rubber band to avoid scratching or marring the finish.
To relieve pressure behind the ear, hold the front of the frame steady with one hand and use the other hand (or padded pliers) to gently bend the temple tip outward, loosening the curve. For adjusting the overall temple width, brace the frame front and angle the temple outward at the endpiece, the small joint where the temple connects to the frame. A wide-jaw or parallel-jaw plier works best for this if you have one, but standard pliers with padding will do.
Metal frames hold their shape well once bent, so you can test the fit immediately. Make adjustments one small bend at a time. It’s much easier to bend a little more than to undo an overbend.
Getting the Curve in the Right Place
One of the most overlooked causes of ear pain is the bend point sitting in the wrong location. The temple should start curving downward right where your ear begins, at the top of the ear where it meets your head. If the curve starts too early, the temple presses down on the top of your ear. If it starts too late, the hook misses your ear and digs into the area behind and below it.
To check this, look at your glasses from the side while someone else wears them (or take a photo of yourself in a mirror). The downward bend should align with the top of the ear. If it doesn’t, you’ll need to reshape the curve so it starts at the correct point. For plastic frames, heat the entire curved section and reshape it. For metal frames, carefully straighten the old bend and create a new one in the right spot.
Silicone Sleeve Covers
If adjusting the frame shape doesn’t fully solve the problem, or if you want a quicker fix, silicone temple tip covers can help. These are soft rubber sleeves that slide over the ends of your temples, adding cushioning between the hard frame material and your skin. They’re widely available online for under $10 and typically come in multipacks with several pairs.
They work well for mild discomfort and for frames that fit correctly but just feel too hard against the bone. They do add a small amount of thickness to the temple, which can make a tight fit feel tighter, so they’re best paired with frames that aren’t already squeezing. Some people find that certain silicone grips create their own pressure points after extended wear, so look for covers that are soft and smooth rather than textured or ridged.
When to Have a Professional Do It
Most optical shops will adjust glasses for free if you purchased them there. Even if you bought your frames elsewhere, many opticians will do a quick adjustment at no charge or for a small fee, typically $10 to $35. It’s worth asking, especially if you’re nervous about bending the frames yourself or if the problem involves both the temples and the nose pads, which can interact in ways that are tricky to balance on your own.
Professional adjustments are also the safer route for rimless frames, frames with soldered joints, or expensive designer frames where a mistake would be costly. Opticians have specialized tools designed to grip specific parts of the frame without damaging the finish, and they can spot fit issues you might not notice, like one temple sitting higher than the other or the frame being slightly warped from being set down unevenly.
If your glasses keep returning to the painful position after repeated adjustments, the frame may simply be the wrong size for your head. Temple length is measured in millimeters and printed on the inside of the temple arm (usually the third number in a series like 52-18-140). A temple length that’s too short for your head will always pull the curve into the wrong position, and no amount of bending will permanently fix it.
