What action should be taken to raise the frame on a pair of glasses?

Loosen the temples
Lower the nose pads
Adjust the bridge
Shorten the temples

The correct answer is: Lower the nose pads

To raise the frame on a pair of glasses, adjusting the nose pads is the most effective action. Lowering the nose pads will result in the frames sitting higher on the nose, consequently raising the entire frame in relation to the wearer's face. This is particularly important for ensuring that the optical centers of the lenses align with the patient's pupils, which is essential for clear vision. Loosening the temples would not effectively raise the frame; instead, it may allow the frames to sit lower or less securely. Adjusting the bridge may influence the fit but does not directly raise the frame itself. Shortening the temples could potentially alter the fit behind the ears but would not have a significant effect on the height positioning of the frame on the face. Thus, lowering the nose pads is the most direct method to achieve the desired adjustment.
