Thick plastic temples create a broad contact area behind the ear, so bend position and contact shape are especially important. Check frame width, bridge support and deformation as well.
The relatively thick temples of many plastic frames create a broad contact area behind the ears, so even a small difference in angle can feel like significant pressure.
Discomfort can increase with longer wear when the bend begins too early or force is concentrated at one point.
Before changing only the area behind the ear, check frame width and bridge support as well.
01 · TEMPLE LENGTH
Does the temple length match the ear position?
If a temple is too short, it may bend sharply before it reaches the correct position behind the ear and press on the upper ear.
If it is excessively long, it may be difficult to make the bend at the proper location, or unnecessary length may remain behind the ear and make the fit unstable.
Even with the same marked length, such as 145 mm, the actual fit changes with front width, hinge position, and head size.
The printed number is less important than where the temple actually meets and passes the wearer’s ear.
02 · TEMPLE BEND
Does the bend follow the shape of the ear?
A plastic-frame temple should continue naturally downward behind the ear.
If the bend starts too far forward, it can press the upper ear; if it is bent too deeply, it can wrap too tightly behind the ear.
If the bend begins too late, the frame may not be supported securely.
Check both where the bend starts and how strongly it is curved.
03 · TEMPLE THICKNESS
Is a thick temple pressing only one area?
Plastic-frame temples are often thicker and wider than metal temples.
A broad surface can distribute pressure when it follows the ear naturally, but if its shape does not match the ear, a wide area may remain under constant pressure.
If only an edge or protruding part of the temple tip touches the skin, localized pain can occur.
04 · ACETATE ADJUSTMENT
Acetate can be shaped for the area behind the ear
Acetate frames can be adjusted to some extent by using controlled heat and fitting technique to change the bend and curve of the temple tip.
This can reduce pressure behind the ear or help prevent the frame from moving forward.
Excessive heat or force in the wrong direction can damage the surface or deform the frame, so adjusting acetate at home with a hair dryer or hot water is not recommended.
05 · EAR HEIGHT
If only one ear hurts, compare ear heights
The left and right ears may sit at slightly different heights.
If both temple bends are made completely identical, one side may receive stronger pressure.
When only one ear repeatedly hurts, compare left-right ear height and bend position together with any frame distortion.
06 · FRAME WIDTH
Incorrect face width can affect the area behind the ears
If the frame is too narrow for the face, the temples can press at the temples and spread outward strongly, transmitting that force behind the ears.
If it is too wide, the temples may not support the frame securely behind the ears and the glasses can move forward.
Even when addressing ear pain, check the overall frame width and how the temples flow from the temples to behind the ears.
07 · FRONT WEIGHT
Is a heavy front being held too strongly behind the ears?
A thick acetate front or large lenses can make the front relatively heavy.
If the temple tips have been bent too deeply to stop that weight from sliding forward, pressure behind the ears can increase.
In this situation, also check whether the bridge supports enough of the front weight and whether the frame width is appropriate.
08 · MATERIAL DEFORMATION
Was it comfortable before but painful later?
Acetate and some other plastic materials can be affected by heat and pressure.
Leaving the frame in a hot vehicle or storing it under pressure on one side can change the shape of the temples.
If glasses that were initially comfortable begin pressing one ear later, check the frame itself for deformation.
SOLUTION GUIDE
Solutions at a glance
Check the bend position against the actual ear position.
Adjust the curve and angle of the acetate temple.
Check the contact surface and where the temple edge meets the ear.
Check left-right ear height and whether the frame is deformed.
Check the overall frame width.
Check bridge support and overall weight distribution as well.
GLANOS FITTING CHECK
GLANOS fitting check
- Is the front aligned?
First check the frame itself for twisting or distortion. - Does the bridge fit the nose?
Check that enough of the front weight is supported on the nose. - Is the overall width appropriate?
Check that the frame and temples flow naturally from the temples toward the ears rather than pressing continuously. - Is the temple bend natural?
Check that the temples bend at an appropriate point according to the position and shape of the ears.
CAUTION
Do not heat plastic or acetate temples at home because the area behind your ear hurts
Acetate can be adjusted with heat, but the correct temperature and direction of force matter. Excessive heating or forcing one area can deform the frame or damage its surface. Opening the temples too much may reduce pain but can also make the glasses slide. Check front alignment → bridge → overall width → temple bend before making only the adjustment that is needed.
