The 'opposite shape' rule is the most fundamental principle in glasses fitting: round faces suit angular frames, square faces suit rounded frames. This contrast principle creates visual balance and has been the backbone of optician recommendations for over 80 years.
Eyewear selection uses principles of visual weight and facial geometric compensation. By applying frames that contrast with the native bone structure, stylists create balance. For example, a heavy browline adds width to a narrow forehead, while round lenses soften angular jaws.
Contrast establishes aesthetic equilibrium. Sharp, angular frames offset soft cheeks, whereas curves soften structural square jaws.
Frame widths should match the temple width of your face to prevent optical distortion and maintain correct pupillary alignment.
High bridges suit frames with high nose keys; low bridges require adjustable pads to prevent slippage and cheek contact.
Oval faces have balanced proportions, allowing them to wear almost any style, from aviators to bold geometric frames.
Angular, rectangular, or geometric frames are best because they introduce sharp lines that lengthen and slim the face's appearance.
Yes, oval is considered the most versatile shape. Frame styles should simply be as wide as the broadest part of the face to preserve balance.
Check the inside temple of an existing pair. It shows three numbers: lens width, bridge width, and temple length in millimeters (e.g. 50-18-140).
Yes, glasses can define jawlines, lift cheekbones, and shorten long faces depending on the frame's color, thickness, and temple position.
