Costa Del Mar Fly Line Sunglasses - Matte Black/Blue Mirror

The Costa Del Mar Fly Line sunglasses are specifically designed for oval and round face shapes due to their extra-large, rectangle design. They may not be the optimal fit for very narrow or angular faces.

Yes, these sunglasses come with standard prescription lenses, allowing you to have them fitted with your specific vision correction by an optician.

Blue mirror lenses are best suited for bright, sunny conditions, especially on open water or when glare is a significant factor. They help reduce glare and enhance contrast.

The frames are made from a matte black injected material, which offers durability and a lightweight feel.

The sunglasses come with a free protective case and a cleaning cloth to help maintain their condition.

Gently wipe the lenses with the provided microfiber cloth. For tougher smudges, use a lens cleaning solution made for eyewear. Avoid abrasive materials or household cleaners.

The MPN (Manufacturer Part Number) for this model is 06S9129.

While injected frames are less adjustable, try slightly bending the temples inwards, or consult an optician for minor adjustments. Ensure the fit is correct for your face shape.

Clean the lenses carefully with the provided microfiber cloth and a dedicated lens cleaner. Ensure no debris is trapped on the cloth.

Contact the optician who fitted the prescription lenses. This is a matter of lens fitting, not a defect of the frame itself.

Given the extra-large, full-rim design, ensure this style is appropriate for your face shape and size. Minor adjustments may be possible by a professional optician.
