The Ray-Ban 4420 sunglasses are designed for adults who seek a blend of bold, modern aesthetics and everyday comfort. Featuring a full-rim square frame in a versatile grey finish, these unisex shades provide excellent utility for daily wear, though the nylon construction favors a lightweight feel over heavy-duty metal durability.

The square frame design is generally very versatile, though it often complements round or oval face shapes particularly well by providing structural contrast.
Yes, nylon is resistant to moisture and perspiration, making these glasses durable for outdoor use, though they should be rinsed with fresh water after saltwater exposure.
The standard green solid-color lenses provide excellent contrast, but please verify the specific technical specs on your packaging to confirm if your model includes polarization.
Yes, the 4420 series supports the installation of prescription lenses; consult with your local optician to confirm compatibility with your specific prescription.
This model features a 65-18 sizing, indicating a 18mm bridge width, which is designed to fit a wide range of adult nose bridges comfortably.
Clean thoroughly with a microfiber lens cloth and authorized lens cleaner; avoid using clothing or tissues.
Because the temples are non-adjustable nylon, consider using silicone temple grips or an eyewear strap for high-movement activities.
Ensure the frame is centered on the bridge; minor adjustments to comfort should be handled by a professional optician to prevent cracking the nylon.
These sunglasses are ready to wear out of the box with no complex setup required. To maintain the integrity of the nylon frame and the lens coatings, it is recommended to store them in a protective hard case when not in use. Clean the lenses daily using a microfiber cloth and a mild soap-and-water solution; avoid using abrasive paper products or household chemicals which can strip the lens tints. Because the frame is made of injected nylon, avoid exposing the glasses to extreme heat, such as leaving them on a car dashboard in direct sunlight for extended periods.
