How they should sit

High on the bridge, close to your brow line, level rather than tilted. From the side, the lens should be roughly parallel to your cheek. This puts the intermediate zone on your screen and the reading zone in comfortable reach with a small chin-down movement.

Signs of a bad fit

Glasses sliding down the nose means the reading zone drifts out of your line of sight — you compensate by tipping your head back, and blame the lens. Arms pressing behind the ears mean they are being worn too far forward. Both are position problems, not optical ones.

Small adjustments

The spring hinges do most of the work. Beyond that, any optician will heat-adjust the temple curve in a couple of minutes, usually for free. Cleaning and care advice is on the care page.
