(1) Overview
The easiest detail to spot on the Rogerson RS11656 sits right where the lens meets the temple: a bow-shaped curved metal end-piece carrying a round raised screw cap that reads like a small watch face. This is a completely rimless drilled frame — the lenses are drilled and screwed at two points per side, the lower edge left bare, no nylon cord; from the side you can clearly see the bushings and the screw heads standing out from the lens surface. The temples are one-piece metal with a thin flat cross-section, wide near the hinge and then tapering back like a sword blade, ending in a flat paddle-shaped metal tip with no plastic sleeve. Rogerson is a trademark that has been granted protection registration in Vietnam.
(2) Materials and finish
The material is titanium with an ion-plated (IP) surface finish — the TITANIUM IP marking is engraved along the inner face of the left temple, right above the row of measurements. Ion plating lays colour down in a vacuum chamber, giving a colour layer that adheres well and takes scratches better than ordinary paint, which is why the technique is used on higher-tier metal frames. It should be said honestly that any plated layer wears down over the years, especially in areas that rub a lot. Titanium is lighter and less likely to irritate the skin than ordinary steel, which counts for something on a model meant to be worn all day.
As for the finish, the bridge is a flat metal bar bent into a soft arch, a little broader at the top and tapering towards both ends, with the two pad arms folded down in a V shape carrying clear teardrop-shaped silicone pads that can be adjusted. The hinge is a screw type with a round cap raised on the end-piece, the driver slot clearly visible — both a decorative detail and a convenience when the temples need tightening. What sets it apart from its sibling RS11655 is that the temple tips of the RS11656 have no plastic sleeve: the part resting behind the ear is flat metal in the same colour as the rest of the frame, which on the dark C3 reads as glossy black.
(3) Specifications
- Frame shape: Horizontal rectangle, all four corners rounded, top edge almost straight
- Rim type: Rimless — lenses drilled and screw-mounted at two points per side, lower edge bare
- Material: Titanium with ion-plated (IP) finish; clear silicone nose pads; one-piece metal temples with no plastic sleeve
- Measurements: 56-18-145 (56mm lens width, 18mm bridge, 145mm temples)
- Intended for: Unisex, adults; medium to large faces, nose bridges that need a slightly wider bridge
- Colours: C1 Polished gold (bridge, end-pieces, hinge screw caps and the whole temple all in polished gold plating, the flat temple tips gold as well); C2 Bright silver (a polished white silver, reflecting strongly at the bridge and the hinge screw caps); C3 Graphite black-grey with a moss-green cast (bridge and end-pieces in a very dark graphite grey close to glossy black, the temples revealing a deep moss green when light strikes them sideways; on this version the temple also carries a C3 suffix engraved after the size row). The product photo set includes a shot of all three colours side by side plus two close-ups of the hinge and the temple, and one look makes the difference in tone between C2 and C3 obvious.
(4) Highlights
- Bow-shaped end-piece with a round screw cap: The identifying detail of this model, clearest in the close-up photos.
- Flat, tapering temples: Wide at the load-bearing section near the hinge, narrowing towards the back — a sensible distribution of stiffness that still looks slim.
- No plastic parts on the temples: The whole temple is a single metal tone, flat tips included, for a clean, uninterrupted look.
- A wider stance: The overall width is greater than on the usual slim drilled frames, and the 18mm bridge is 1mm wider than on the RS11655.
- Adjustable silicone nose pads: Bend them to set the height and spread for each nose bridge.
(5) Who it suits
- People who like minimalism but still want one accent: The round screw cap on the end-piece is the one detail on these glasses that gives the eye something to look at.
- Nose bridges that need more room: The 18mm bridge suits anyone who finds 16–17mm bridges a little tight across the nose.
- Medium to large faces: A 56mm lens width along with the wide stance.
- People who dislike plastic-sleeved temple tips: Flat metal tips are easy to clean and do not fade the way plastic does over time.
- People who wear dark office clothing: The C3 graphite grey with its moss-green cast is muted and discreet in any work setting.
(6) Choosing lenses and keeping the frame in good shape
- Let us say it plainly from the start: a drilled frame cannot take every type of lens. The lens has to be drilled for the screws, so brittle materials will develop hairline cracks around the holes. Glass lenses and CR-39 plastic at index 1.50 / 1.56 belong to that group and should not be used.
- Choose index 1.60 or higher, or polycarbonate / Trivex: these materials are tougher and handle the clamping force around a drill hole considerably better.
- A higher prescription means a thicker, heavier lens edge, and more pressure on the two screw points — bring your prescription or your dioptre figures so the technician can work out the right material, index and edging method.
- Do not turn the screws yourself at home: over-tightening is the most common cause of cracked lenses on drilled frames.
- Take the glasses off with both hands: rimless frames handle twisting less well than fully rimmed ones, and a long-standing one-handed habit throws both the front and the lens axis out of alignment.
- Clean gently: a microfibre cloth with a dedicated solution; hot water and harsh chemicals make the ion-plated layer lose colour faster, particularly at the flat temple tips that are in constant contact with the skin.
(7) Frequently asked questions
Q: Is this model in stock at the store, and how long until I receive an order?
A: The Rogerson RS11656 is an order item, reserved in advance rather than displayed on the counter. Tell us the colour code you need (C1, C2 or C3); the shop checks and confirms a specific arrival time before taking a deposit to hold the piece. The frame comes with a 12-month warranty.
Q: Where can lenses be fitted to this drilled frame, and which lenses should I choose?
A: Kính Mắt Điện Biên Phủ at 529 Đường 3 Tháng 2, Quận 10, TP.HCM handles eye testing, index advice and drilling and fitting the lenses on site. With this drilled screw-mounted construction, use lenses of index 1.60 or higher, or polycarbonate / Trivex; glass and CR-39 1.50 / 1.56 should not be used, as they are brittle and crack easily around the drill holes.
Q: How do I know whether 56-18-145 fits my face?
A: A 56mm lens width, 18mm bridge and 145mm temples are on the slightly larger side, suiting medium to large faces and nose bridges that need a wider bridge. You can compare them with the numbers printed on the pair you currently find the best fit; better still, come to the store and try them on, since how well they fit also depends on your nose bridge height and pupillary distance.
(8) Conclusion
The Rogerson RS11656 is the choice for someone who wants rimless glasses but still likes one handsome detail to look at — the bow-shaped end-piece with its round screw cap, flat tapering titanium temples, and not a single piece of plastic on the temples. This construction calls for lenses tough enough to take it: index 1.60 or higher, or polycarbonate / Trivex. Send us your prescription and the colour code you want; the shop will advise on the lens material and confirm the arrival time first, and there is no rush in deciding to order after that.
