Quick Answer

For most face shapes, round frames soften angular features, while square frames add structure to softer faces. If you have an oval or heart-shaped face, round frames like the Cassian Round Oval offer a flattering balance; if you have a round or oblong face, square frames like the Therese Oversized Square add definition.

Why Shape Matters

The shape of your eyeglass frames can change the perceived proportions of your face. Round frames tend to soften sharp jawlines and foreheads, while square frames add angles to rounder or longer faces. Choosing the right shape can enhance your natural features and ensure a more balanced look.

Material and Comfort Considerations

Beyond shape, the material of the frames affects comfort and durability. For example, the Therese Oversized Square is crafted from premium TR and metal materials, offering a lightweight yet sturdy feel. If you wear glasses all day, lightweight materials reduce pressure on your nose and ears, making them a practical choice for extended wear.

Prescription Sunglasses: A Dual Purpose

If you need prescription sunglasses, you can combine the benefits of UV protection with your corrective lenses. The Monaco Round Sunglasses and Bon Voyage Square Sunglasses are both available with prescription lenses, allowing you to enjoy the style you want without compromising on vision correction. Consider how the frame shape complements your face when choosing between round and square options.

Round vs Square: Trade-Offs and Decision Rules

  • Round Frames: Round frames soften angular features like a square jaw or sharp cheekbones. They work well for diamond, heart, and square face shapes, adding a touch of retro elegance. If you have a square face, round frames can balance your angles.
  • Square Frames: Square frames add structure to round or oval faces, making them appear more defined. They also convey a bold, modern look that suits professional settings. If you have a round face, square frames can add definition.
  • Face Shape Compatibility: Refer to the frame's face shape compatibility. For example, the Monaco Round Sunglasses are ideal for Square, Heart, Oval, and Oblong faces, while the Therese Oversized Square suits those seeking a chic statement. Always check the frame's face shape compatibility before purchasing.
