(1) Overview
Among the Rogerson drilled rimless frames, the RS11658 plays the sharpest contrast between metal and plastic: the front half of the temple is a flat metal bar curved into a polished crescent, while the rear half is wrapped in a thick plastic layer around a metal core that runs all the way to the rounded tip. The frame front is the opposite — minimal to the point of being severe: flat rectangular lenses drilled and screwed onto two metal end pieces, with both the upper and lower edges left bare, no rim and no nylon cord. The bridge is a metal bar bent into a softly angled arch, with two slim pad arms carrying clear silicone nose pads. The measurements are 55-18-140, with temples shorter than the usual standard, which suits people whose ears sit a little high or who have a smaller head.
(2) Materials and finish
The frame itself is titanium with an ion-plated (IP) finish — exactly what the TITANIUM IP marking printed on the left lens says, alongside the model and size line RS11658 55□18-140. Ion plating applies colour inside a vacuum chamber, so the coat grips more firmly and takes scratches better than ordinary paint, which is why the technique is used on high-end metal frames; even so, every plated layer grows thinner over years of use. Titanium is light and less irritating than ordinary steel, a plus for a frame that rests on the nose all day.
The plastic wrapped around the rear half of the temple is what really decides how each colour code looks: C1 uses a tortoiseshell plastic in amber brown streaked with black, while the other two use solid black plastic. This plastic layer also makes the section resting on the ear more comfortable than a bare metal wire. The hinge is a small screwed metal joint, set back behind the curved metal section. The RS11658 has no decorative engraving on the temples — only the small ROGERSON EYEWEAR lettering with a CE mark at the front of one temple, while the front of the other temple repeats the model code and the measurements. Rogerson is a trademark registered and protected in Vietnam.
(3) Specifications
- Frame shape: flat horizontal rectangle, slim profile
- Rim style: rimless — drilled and screw-mounted, no nylon cord
- Material: titanium with an ion-plated (IP) finish; plastic-wrapped rear half of the temples, clear silicone nose pads
- Measurements: 55-18-140 (55mm lens width — 18mm bridge — 140mm temple length)
- Who it's for: unisex, suits medium-sized faces; 140mm temples lean towards the short side
- Colours: C1 Gold with tortoiseshell temples (polished gold-plated metal, with the rear half of the temples in amber-brown tortoiseshell plastic streaked with black — the only code with a contrasting coloured plastic detail), C2 Silver with black plastic temples (mirror-bright white silver with solid black plastic, the most neutral of the three), C3 Smoke grey with black plastic temples (a deeper gunmetal than C2, not mirror-bright, with the same black plastic on the temples). The product photo set includes a shot of all three colours side by side — the quickest way to see the difference in tone between C2 and C3 — along with close-ups of the hinge and temple.
(4) Highlights
- Hybrid metal-and-plastic temples: they keep the slimness of a metal wire along the body of the temple but add a softer plastic layer where it rests on the ear, so you don't have to choose one or the other.
- The C1 tortoiseshell version: rarely seen on a drilled rimless frame; the amber-brown grain streaked with black softens the coldness of the gold metal.
- The crescent-curved metal bar at the temple front: the one shaping detail on this model, polished bright, standing in for an engraved pattern.
- 140mm temples: shorter than the 145mm of most models in the same Rogerson batch, so there is less bending needed for people with a smaller head.
- A frame front bare at both top and bottom: it barely crosses your line of sight, and the face looks more open.
(5) Who it suits
- People who find bare metal frames too cold: the plastic wrap on the temples is warmer to the touch and feels less slippery behind the ear.
- People whose temples are always too long: 140mm is on the short side and usually fits better for a smaller head or higher-set ears.
- People who want one touch of colour: the C1 tortoiseshell version adds a bit of flair, while C2 and C3 stay completely neutral.
- Office workers who need a light frame for constant wear: slim construction, no rim, and little weight bearing down on the nose.
- People torn between silver and smoke grey: C3 is noticeably deeper than C2 when placed side by side, and the three-colour photo makes the decision quick.
(6) Choosing lenses and keeping the frame in good shape
- This needs saying up front: this is a drilled frame, and the lenses are drilled for the screws, so it cannot take every type of lens. Glass and CR-39 plastic in index 1.50/1.56 are too brittle and tend to develop hairline cracks spreading out from the edge of the drill hole.
- Choose index 1.60 or higher, or polycarbonate / Trivex — tough materials that handle the clamping force of the screws far better.
- With a strong prescription the lens edge is thicker and heavier, so the pressure on the drill holes rises accordingly; the technician will reconsider the hole placement and how the edge is ground to suit.
- Take the glasses off with both hands: twisting force on one side is the enemy of a drilled frame, because there is no rim to share the load.
- Check the screws periodically: the lens screws loosen over time, and a quick visit to the shop to tighten them early will prevent the lens from rotating out of axis.
- Look after the plastic on the temples: don't leave the glasses in a car parked in the sun for long — high heat wears down both the plastic and the plating faster.
(7) Frequently asked questions
Q: Do you have this in stock at the counter, and how long does an order take?
A: The RS11658 is an order-in item and is not kept at the counter. Message us or drop by, and we will check and tell you the estimated arrival time before taking any deposit to reserve it — the deposit only comes after that, so you are never left waiting in the dark.
Q: Where can I have lenses fitted to this drilled frame, and which lenses are safe?
A: We drill and fit on site at 529 Đường 3 Tháng 2, Quận 10, with an eye test and advice on lens index before cutting. For drilled frames, use index 1.60 or higher, or polycarbonate / Trivex; glass and CR-39 in 1.50/1.56 are too brittle and crack easily around the drill holes, so we do not fit them.
Q: Will 140mm temples be too short for me?
A: The full measurement is 55-18-140, meaning the temples are 5mm shorter than the 145mm models in the same Rogerson batch. Someone with a larger head or ears set further back will find it a little tight, while a smaller head will find it a better fit. The surest way is still to try it on; our staff will adjust the pad arms and the curve of the temple tips on the spot.
(8) Conclusion
The Rogerson RS11658 is a drilled rimless frame for someone who wants to keep the slim look of metal but still likes the softer feel of plastic where the temple rests on the ear, with the C1 tortoiseshell version offering a coloured choice alongside the two neutral ones. The 140mm temples are worth noting — good for a smaller head, and worth thinking about if you are used to longer temples. It is an order-in item with a 12-month warranty; come by the shop to try the size and talk through the lens choice properly before settling on a colour.
