Persol Guido PO3393S - Black

The Persol Guido PO3393S sunglasses with M3 lens treatment are best suited for bright, sunny conditions. For very overcast or low-light environments, a different lens tint might offer better visibility.

The 'M3' typically refers to the lens color and treatment. For Persol, this often indicates a specific shade and potentially anti-reflective or polarized properties, designed for optimal light conditions.

These are designed as a unisex model, meaning they are intended to fit a wide range of adult face shapes. However, for a precise fit, it is recommended to try them on or consult the product dimensions if available.

Persol typically offers a manufacturer's warranty against defects in materials and workmanship. The specific duration and terms vary by region and retailer, so it's best to check the warranty information provided at the time of purchase.

Yes, lens replacement is often possible. Contact an authorized Persol dealer or a reputable optical shop to inquire about replacement lens services.

The 'M3' designation does not inherently confirm polarization. Polarization is usually explicitly stated. Please check the product details or packaging for confirmation on whether these lenses are polarized.

Visit an optician or a Persol retailer for professional adjustment. They can gently bend the frames for a more comfortable fit.

Clean the lenses using a microfiber cloth and a lens cleaning solution specifically designed for eyewear. If unavailable, use mild soap and water, then rinse and dry carefully.

Avoid attempting to fix it yourself. Take the sunglasses to a professional optician who can assess and adjust the frame without causing damage.
