Persol PO3398S - Blue

The blue lenses offer good color contrast and reduce bright light effectively, providing comfortable vision in sunny conditions and reducing glare.

They are ideal for bright, sunny conditions. For very low light or overcast days, lighter or clearer lenses might be more appropriate. They offer excellent UV protection regardless of the light conditions.

The acetate frame can be wiped gently with a soft, damp cloth. Avoid harsh chemicals or soaking the frame.

Cobalto is a specific shade of deep, rich blue, giving the sunglasses a distinctive and sophisticated appearance.

The product description does not explicitly state if these lenses are polarized. For confirmation, please check the detailed product specifications or consult the retailer.

Minor adjustments can sometimes be made by a professional optician. For significant looseness, consider adding a specialized nose pad or consulting a professional for fitting.

Use a clean microfiber cloth and a small amount of lens cleaning solution specifically designed for eyewear. Gently wipe in a circular motion.

While acetate frames are generally comfortable, individual face shapes vary. If discomfort persists, it's advisable to consult an optician to check the fit or explore alternative models.
