When adjusting a library temple, where should it touch the side of the head?

The appropriate placement for a library temple when adjusting it is directly at the top of the ear to the tip of the temple positioned behind the ear. This alignment ensures that the eyewear sits comfortably and securely on the wearer’s head.

When the temple of the glasses rests at the top of the ear, it helps distribute the weight of the glasses evenly. This positioning also allows for adequate support while preventing the frames from slipping down the nose or pinching the sides of the head. Proper adjustment in this area is crucial for maintaining comfort and ensuring that the lenses are correctly positioned in front of the eyes for optimal vision.

The other options do not reflect the ideal contact point for a library temple. While some suggest adjustments at different points or emphasize a certain angle, those placements may lead to an improper fit, affecting both comfort and visual accuracy for the wearer.
