Square Prescription Sunglasses
by Courtney Dryer, OD, May 31, 2025
Square prescription sunglasses may be one of the most popular shapes of eyewear. Their defined, angular lines and square frames add confidence and sophistication to any outfit while providing essential UV protection and vision correction. Square frames are especially flattering on round and oval faces, where the angular shape creates balance and adds dimension. You will find square frames made in a range of materials, from classic acetate to lightweight metal. Ideal for everyday wear, they are a practical yet stylish accessory.

Square sunglasses for different face shapes
Square sunglasses are particularly flattering on round and oval face shapes. For round faces made of soft curves and minimal angles, square frames add structure and definition, helping to elongate the face. The angular lines of square sunglasses create a sharp contrast to the natural contours of a round face, balancing out the overall shape. Opting for bold, thick square frames can enhance this effect, adding edginess and style to an otherwise soft face shape.
For oval faces, square sunglasses offer a sophisticated and proportional look. Since oval faces are naturally balanced, most frame shapes work well; however, square sunglasses add definition and polish without overpowering the face. The broad top and angular lines of square frames fit well with the contours of an oval face, creating a fresh silhouette. Both an oversized or more streamlined square frame will complement the balanced proportions of an oval face for a stylish look fit for any occasion.
The perfect frame color and material for your square sunglasses
Frame color, material, and comfort should be considered when choosing a frame. The perfect frame color and material should enhance your appearance and reflect your personal style. Neutral colors like black, tortoiseshell, or dark brown are classic and versatile. These colors work well with many outfits. Bold frame colors like deep blue, green, purple, or burgundy can make a statement. Transparent acetates in pink or gray have been trending for years and are increasing in popularity.
You may also want to consider your skin tone when choosing the perfect rectangle prescription sunglasses. You have a warm skin tone if your veins appear green or green-blue. Emerald green, purples, lavender, pink, light blue, and bright blues may look better on those with a cool undertone. Frames in this color family are best paired with a gray or G15 lens tint. Peach, coral, and other neutral tones frames like beige and gray are good choices for those with warm undertones. Frames in this color family are best paired with a brown or a G15 lens tint.
Square frames can be made from either acetate or a combination of metals. Acetate frames blend style and comfort and are available in various colors, patterns, and finishes. Titanium frames may feel more modern with their sleek, thin appearance. They appear “barely there.” If you are sensitive to the frame on your nose or ears, you should consider the frame weight. If you have a low bridge, a frame with nose pads may help balance the weight on the nose.
Square prescription sunglasses can be ordered in a wide range of lens prescriptions, tints, and colors. They can be ordered with polarized lenses for the best visual clarity, enhancement of color, and reduction of glare. Tints or mirrored lenses of different hues can add a unique element to the look of your sunwear.
Whatever square sunglass frame you choose, it should complement your skin tone and face shape and represent your personality. It’s important to have fun with your prescription sunglasses while protecting your eyes from the sun.
