The bridge size refers to the distance between the lenses of the sunglasses, measured from one lens to the other at the bridge of the nose. It ensures a comfortable fit across your nose. Typical sizes range from 14mm to 24mm.

Frame size is typically indicated by three numbers: lens width, bridge width, and temple length (in millimeters). For example, a frame size might be listed as 50-20-140, where 50mm is the lens width, 20mm is the bridge width, and 140mm is the temple length.

Temple length is the distance from the hinge of the frame to the end tip that rests behind your ear. It usually ranges from 120mm to 150mm. Measure from the hinge to the tip of the temple arm, following the curve of the arm.

1. Round Faces: Rectangular or square frames can add structure and balance.

2. Square Faces: Round or oval frames can soften angular features.

3. Oval Faces: Most frame shapes work well, including geometric and classic styles.

4. Heart-Shaped Faces: Frames with a wider bottom, like aviators or cat-eyes, can balance out a narrower chin.

Measure the width and length of your face. Compare your measurements to common face shapes: round, square, oval, or heart. Your face shape can help guide you in selecting flattering sunglasses.

Polarized lenses reduce glare from reflective surfaces like water and roads, providing clearer vision and reducing eye strain. Non-polarized lenses don’t offer this glare reduction but are often less expensive.

Yes, all Zealous sunglasses come with scratch-resistant coatings to help maintain clarity and durability. However, proper care and cleaning are essential to prolong the life of your lenses.

1. Gray: Reduces overall brightness while preserving natural color balance.

2. Brown/Amber: Enhances contrast and depth perception, ideal for variable light conditions.

3. Yellow/Gold: Improves contrast and depth perception in low-light conditions.

Lens curvature impacts how well the lens conforms to your eye's natural shape. Curved lenses can provide a wider field of vision and better peripheral protection.

Use a microfiber cloth and lens cleaner designed for eyewear. Avoid using paper towels or clothing, as they can scratch the lenses. Gently wipe in a circular motion to remove smudges.
