The Ray-Ban RB4288L is built around a bold, square silhouette that makes its presence known without overreaching. A full-rim injected nylon frame gives the shape clean, defined edges and a substantial profile that holds its structure through daily wear, while the lightweight nylon construction keeps the frame from becoming uncomfortable during long hours of outdoor activity. The result is a frame that looks serious and refined without feeling heavy on the face - the kind of balance that Ray-Ban has been calibrating since the brand first introduced performance-driven eyewear for active use.
The lens is a gradient cut, meaning it transitions from a darker tint at the top to a lighter tint toward the lower portion of the lens. This grading is designed for the way outdoor light actually works: the overhead sun is the primary source of glare, and the darker upper portion shields against it while the lighter lower field keeps the ground and foreground in clearer view. For anyone who spends time outdoors across varying light conditions, a gradient lens handles the full range more naturally than a uniform-density tint that can block too much or too little depending on where you're looking. The 57mm lens width provides high coverage across the face, extending the protection zone toward the temples on both sides.
The RB4288L arrives with Ray-Ban's standard accessories package: a microfiber cleaning cloth and a hard case that protects the frame and lens when they are not being worn. For the active lifestyle wearer who wants the credibility and quality of Ray-Ban in a contemporary square silhouette that reads as modern rather than retro, the RB4288L delivers that in a frame that transitions cleanly between sport, casual, and social settings.

Q&A
Q: What is a gradient lens and how does it differ from a standard tinted lens?
A gradient lens has a tint that varies in density from top to bottom. The upper portion of the lens is darker to shield against overhead sunlight, while the lower portion is lighter to keep the ground and immediate foreground in clearer view. A standard uniform-tint lens applies the same density across the entire lens, which can block the lower field more than necessary for most outdoor situations. Gradient lenses are a practical choice for lifestyle and everyday outdoor wear where the primary concern is overhead glare rather than reflective surface glare.
Q: Are these lenses polarized?
No. The RB4288L uses a gradient lens that is not polarized. Polarized lenses add a filter that specifically blocks horizontally polarized light, which is particularly useful for reducing glare from flat reflective surfaces like water, wet roads, or snow. For general outdoor lifestyle use and fashion wear, a non-polarized gradient is a versatile and practical choice.
Q: What does the 57-17-145 size measurement mean?
The three numbers represent the three key frame dimensions. The 57 is the lens width in millimeters, measured across the widest point of one lens. The 17 is the bridge width, the distance between the two lenses at the nose. The 145 is the temple length, the arm that extends from the frame to behind the ear. Together, these three measurements define the overall fit and coverage of the frame. At 57mm, the RB4288L is sized toward the larger end of the spectrum, providing broad, high-coverage protection across the face.
Q: What is the frame made from and how durable is it?
The RB4288L frame is made from injected nylon, a lightweight thermoplastic that is molded under pressure to produce precise, consistent frame shapes. Injected nylon is durable, flexible enough to withstand daily wear, and resistant to the warping and brittleness that can affect less durable plastics over time. It is standard in Ray-Ban's lifestyle and fashion collections and has a long track record of reliable performance.
