The adjustment needed for a frame that is too loose around the temples is?

When a frame is too loose around the temples, it often means that the temple length is excessive. Shortening the temple length helps create a better fit by ensuring that the arms of the frame hug the sides of the head more snugly. This adjustment allows the glasses to sit properly and helps prevent them from sliding down the nose or feeling unstable.

In contrast, widening the temple arms would increase the overall size of the frame and could contribute to a looser fit. Applying adhesive pads would not address the fit directly and could compromise comfort. Using adjustable temple tips could help with minor adjustments but would not effectively resolve the issue of overall length. Thus, shortening the temple length is the most effective solution for achieving a secure and comfortable fit.
