A 1965 guide to frame selection:

SHAPE: to flatter facial contours in providing the illusion of the “perfect oval. ” The patient’s personal preference must be tempered by technical requirements of the lens and fitting problems.

COLOR: To accent the patient’s wardrobe by blending or contrasting with basic colors or accessories. Seasonal factors are important as are current trends in other fashion fields.

DESIGN DETAIL: to be selected for the occasions on which the eyeframe will be worn. No longer a “trim” added to a frame, design detail is an integral part of the styling and determines the end use of the frame.
