Oakley HSTN SQ Sunglasses - Grey - Prizm Ruby

O_Matter is a durable, lightweight frame material developed by Oakley that offers high performance and comfort.

The Prizm Ruby lenses are best suited for medium to bright light conditions. For very sunny days, they offer good protection, but they may not be ideal for overcast or very low-light environments.

Gently wipe the Prizm lenses with a soft, microfiber cloth. For tougher grime, use a lens cleaner specifically designed for eyewear and a microfiber cloth. Avoid abrasive materials or harsh chemicals.

Lens replacement options may be available through Oakley or authorized service centers, depending on the specific model and availability.

The 'SQ' likely refers to the squared-off silhouette of the sunglasses, distinguishing them from other HSTN models.

The product information does not specify if these particular Prizm Ruby lenses are polarized. Prizm technology enhances color and contrast, while polarization reduces glare. Check the specific product listing for polarization details.

Oakley typically offers a limited warranty against manufacturing defects. Please refer to the official Oakley website or your purchase documentation for specific warranty details.

Ensure lenses are clean and free from debris. Fogging can also occur due to temperature differences; allow the sunglasses to acclimate to the ambient temperature.

Adjust the nose pads if applicable, or consider using a sunglass strap for a more secure fit during active use. The O_Matter frame may also slightly mold to your head over time.

The Prizm Ruby lenses are optimized for brighter conditions. For low-light use, consider alternative lenses with higher light transmission. Clean the lenses thoroughly.
