Part of Ray-Ban's Justin line, the RB4165 is a square sunglass in colour 687380 — opal grey lightweight nylon with a matte finish and matching temples. It is a full rim frame on a high bridge fit, built to be worn daily rather than saved for occasions. Browse the rest of our Ray-Ban range, or see how it sits against the other square sunglasses we stock.
Who the RB4165 suits
The RB4165 is a small frame — 55mm lens, lightweight nylon temples, regular width across the front. Ray-Ban lists it as suiting oval and round face shapes. It is listed as men, and sits with the rest of our men's sunglasses. The only fit test worth trusting is a direct one: hold a pair you already wear beside this frame and compare the numbers stamped inside the temple. If the lens width is close and the bridge matches, the fit will be close too.
Lens and UV protection
The RB4165 ships with dark blue polycarbonate lenses, a solid tint that darkens evenly across the whole lens. At 15.3% light transmission it is a dark tint made for bright sun and open glare, and still fine for driving. Every lens blocks 100% of UVA and UVB — full UV400 protection.
Size and fit
The size code is 55–16–145: a 55mm lens, a 16mm bridge and 145mm temples. Those three numbers are printed on the inside of the left temple arm on every Ray-Ban, including whatever you are wearing now. Measure the lens width on a pair you already own and compare it against this frame's 55mm. Full measurements are in the Product Details panel.

Ray-Ban RB4165 — common questions
Does the RB4165 come with lenses?
Yes. It arrives with Ray-Ban's own dark blue sun lenses fitted and ready to wear straight out of the box. If you'd rather have your prescription in them, we can do that too — message us on WhatsApp and our team will talk you through the options.
What size is the RB4165?
55–16–145, which is a 55mm lens, 16mm bridge and 145mm temples, a small frame. Check the inside of the temple arm on a pair you already own; the same three numbers are printed there.
Is the RB4165 polarised?
No. These lenses are tinted and carry full UV400 protection, but they are not polarised — and a tinted lens is not the same thing as a polarised one. If glare off road and water is your main concern, message us on WhatsApp and we'll point you at the polarised models we stock.

Not sure which lens fits your prescription? Here's a quick breakdown.
The right choice if you need correction for one distance only, whether that's reading, distance, or everyday wear. Most common, most straightforward.
No prescription needed. Choose this if you just want the frame for its look, or want a blue-light filter for screen use without any correction.
One lens, seamless correction from near to far, with no visible line between zones. Ideal if you already wear progressives, or want to stop switching glasses through the day.
