01 · ASYMMETRIC FORCE

One-handed removal loads one side first

If the right temple is pulled outward first with the right hand, the opposite side remains on the face and follows later.

The amount and direction of force on the two sides can therefore differ.

One-handed removal does not automatically distort a frame. However, pulling one temple outward first and twisting the frame creates unequal loads on the two sides, so repeated use of the same motion can make asymmetrical changes more likely in an already loose hinge or a thin, flexible frame.

02 · HINGE

Twisting force can repeat at the hinge

Hinges are primarily designed for the temples to open and close in their intended direction.

Repeatedly pulling and twisting one side can add unnecessary stress to the screw and hinge joint and may contribute to play or alignment change over time.

The effect depends strongly on construction. Spring hinges, temple material, hinge barrels and screws, and frame thickness all change how the same handling force is absorbed, so a specific failure should not be attributed to one-handed removal alone.

03 · TEMPLE SPREAD

One temple can gradually spread more

Repeated removal from the same side can apply more outward force to one temple.

That can alter left-right side support and contribute to one-sided drift or rotation.

04 · FRONT FRAME

The force can reach the frame front

Thin metal frames can transmit repeated torsion into front alignment.

Plastic frames can also receive asymmetric stress around the hinge and front connection.

Whether the front has actually distorted should be confirmed by alignment, not assumed from the habit. If one lens sits farther forward or one rim is higher, consider impact, storage and lens mounting as alternative sources of force as well.

05 · TWO HANDS

Use both hands when practical

Holding both temples and removing the frame forward reduces the amount of force concentrated on one side.

It is a small habit, but over time it can help reduce asymmetric deformation.

SOLUTION GUIDE

Key points at a glance

1. Hold both temples

Avoid pulling only one side.

2. Open both sides with similar force

Do not over-spread them.

3. Move the frame naturally forward

Avoid twisting it off.

4. Store it in a case when not in use

Reduce unnecessary external force.

GLANOS FITTING CHECK

GLANOS fitting check order

  1. Front
    Check for twist after repeated one-handed removal.
  2. Nose pads / bridge
    Check for changes in left-right contact.
  3. Width
    Check whether one temple has spread more.
  4. Temple bend
    Compare rear support on both sides.

CAUTION

One one-handed removal does not destroy a frame

The concern is repeated asymmetric force in the same direction over a long period. Using both hands when practical can help reduce the chance of left-right distortion.
