Nike Fire L P Fd - Grey

'Polar Red Flash' refers to the lens color and treatment. 'Polarized' means the lenses reduce glare, while 'Red Flash' indicates a red mirrored coating on the lens surface. This combination offers a vibrant look and enhanced contrast in bright light.

While they offer good grip and are lightweight, their primary design is for fashion and everyday use. For intense sports with high impact, dedicated sports eyewear might be more appropriate.

The frames are made from injected fabric, providing a durable and lightweight construction.

These are typically worn over the face, not over prescription glasses. If you require vision correction, you may need to consider prescription sunglasses or contact lenses.

These are designed as unisex adult sunglasses. While they aim for a standard fit, individual facial structures vary. It's recommended to try them on if possible, or review product dimensions if available.

The manufacturer part number (MPN) for this product is 1819 021.

Ensure the frames are clean and free of oil. If the issue persists, consider consulting an optician for professional fitting or slight adjustments.

Inspect the lenses carefully. If damage is recent and caused by improper cleaning, try cleaning with a microfiber cloth. If scratches are deep, lens replacement might be necessary.

The Polar Red Flash lenses are optimized for bright conditions. For low-light use, consider switching to sunglasses with lighter or different lens tints, or removing the sunglasses if safe to do so.
