Ray-Ban Justin RB4165 - Light Havana Brown Gradient - 710/13 51-16

The frame of the Ray-Ban Justin RB4165 is made from durable and lightweight nylon.

These sunglasses feature a unisex design, making them suitable for both men and women.

Use a soft, clean microfiber cloth specifically designed for eyewear. For stubborn smudges, use a dedicated lens cleaning spray or a very mild soap solution with water, then gently wipe dry.

The '51' typically refers to the lens width in millimeters, and the '16' refers to the bridge width (the distance between the lenses) in millimeters. These measurements help determine the overall fit.

Info needed: The specific lens code 710/13 does not inherently confirm polarization. Please refer to the product's detailed specifications or packaging for polarization information.

Yes, replacement lenses for the Ray-Ban Justin RB4165 are generally available through authorized Ray-Ban retailers or optical professionals. It's recommended to use official replacement parts to ensure proper fit and optical quality.

Info needed: Ray-Ban typically offers a manufacturer's warranty against defects. Please check the specific warranty information provided at the time of purchase or on the official Ray-Ban website for full details.

Clean lenses thoroughly using a microfiber cloth and appropriate lens cleaner. Ensure the cloth is clean to avoid scratching.

While nylon frames offer some flexibility, significant adjustments should be performed by an eyewear professional to avoid damaging the frame. Minor slippage can sometimes be improved with proper placement on the nose bridge.

Small amounts of eyewear-safe lubricant can be applied to hinges if they feel stiff. Avoid bending the frame forcefully, as nylon can break under excessive stress.

Small scuffs on nylon are often unavoidable with regular use. You can try a very gentle wipe with a damp cloth, but deep scratches typically cannot be removed. Focus on preventative care by using the protective case.
