Nike Vital Flow - Silver

A 4-base lens has a slight curvature, providing a balance between a flatter, classic look and adequate coverage for everyday wear. It's less curved than sports-specific lenses.

The Nike Vital Flow is designed for everyday comfort and style. While they offer UVA/UVB protection, their 4-base flat lens design may not provide the secure fit or wrap-around coverage needed for high-impact sports.

The frame is made from an injected material that uses at least 40% castor bean oil. This is a more sustainable alternative to traditional plastics, offering durability and a lightweight feel.

Nike Max Optics are designed to provide precise vision from all angles. Ensure the glasses sit correctly on your face and that the lenses are clean for optimal clarity.

The slim profile contributes to a comfortable, lightweight feel and a discreet aesthetic, making the glasses easy to wear for extended periods and versatile with various outfits.

The product description does not specify if the lenses are replaceable. For any lens-related issues or modifications, it is recommended to consult an optical professional or the manufacturer.

Gently adjust the temple arms by bending them slightly. For tightening, bend them inwards; for loosening, bend them outwards. Make small adjustments and test the fit frequently to avoid over-bending.

Use a dedicated lens cleaning solution or a mild soap with water. Wipe dry with a soft microfiber cloth. Avoid using paper towels or clothing, as they can scratch the lenses.

The injected frame material might become stiff if exposed to extreme temperatures. Allow the glasses to return to room temperature. If stiffness persists and adjustment is needed, apply gentle, controlled pressure.
