Rowan Optical Kent Classic Square
Built for daily single-vision wearers who need a stable square frame that keeps its alignment against body heat.
Mazzucchelli Cellulose Acetate and Beta-Titanium
Frames cut from plant-derived Italian acetate and paired with Japanese titanium temples. The materials hold adjustment and resist skin oils.
Five-Barrel German Hinges
Milled stainless steel hinges riveted directly into the acetate core. They maintain arm tension across months of folding.
Individual Bench Alignment
Each assembled frame sits on a four-point levelling plate before packing. We verify temple parallelism and hinge torque manually.

The combination of Mazzucchelli acetate and a titanium core gives this frame structural reliability. The temple tension remains steady without biting into the mastoid bone.

Five Details That Define the Kent
Mazzucchelli Acetate
Derived from organic cotton fibres and wood pulp rather than cheap petroleum plastics.
Beta-Titanium Core
Allows cold bending by an optician without snapping or weakening the temple structure.
Precision CR-39 Lenses
Delivers flat, predictable light refraction with high clarity and low visual dispersion.
German Steel Hardware
Heavy-duty five-barrel hinges prevent the loose, floppy temples common in glued frames.
Hand Polished Finish
Tumbled in pumice and hand-buffed for smooth surfaces against the skin.
Frame Fit Over Time
Clear Optical Alignment
The CR-39 lenses sit directly before the pupils with minimal peripheral aberration.
Acetate Settling
The cellulose acetate settles against nasal contours for balanced weight distribution.
Structural Retention
The riveted steel hinges and titanium core prevent the frame from stretching out of shape.
Frame Details and Build
The Kent frame is an optical daily-wear spectacle with a balanced square silhouette. We cut the frame front from blocks of Mazzucchelli Cellulose Acetate, a plant-derived material that retains polished depth and resists warping from body heat. The internal structure uses Japanese Beta-Titanium for the temple cores, giving the arms enough flex to adjust against the temples without losing tension over repeated wear. The optical inserts are machined from CR-39 Optical Polymer, surfaced for flat single-vision correction. Each arm connects to the frame front using German Stainless Steel Hinges secured by dual mechanical rivets. This hardware stops the temples from drifting loose, keeping the optical centres aligned with your line of sight through standard daily use.

Fitting and Care Protocol
Check that the nose pads rest evenly and wipe the CR-39 lenses clean with the dry microfiber cloth.
Fold the left temple first, then the right, and place the frame inside the supplied hard shell case.
Do not leave the acetate frame on a vehicle dashboard in direct sun, as concentrated heat can alter frame shape.

Frequently Asked Questions
What lenses come fitted in the frame? +
The frame comes fitted with single-vision CR-39 Optical Polymer lenses surfaced to clear specifications.
Can my local optician adjust the frame fit? +
Yes. The Mazzucchelli Cellulose Acetate softens under standard optical frame warmers, and the Japanese Beta-Titanium core wire holds custom temple curves.
How should I clean the lenses and acetate? +
Rinse the glasses under lukewarm tap water to remove grit, then wipe the lenses dry using the supplied microfiber cloth. Do not use household glass cleaners or solvent wipes on acetate.
What payment methods do you accept? +
Payment is completed either by cash on delivery or direct bank transfer.
Customer Feedback
"The acetate has good weight to it. The temples do not pinch behind the ears, and the lenses are very clear for computer reading."

"The hinges feel solid when opening the glasses. They sit straight on my nose bridge without sliding down throughout the day."

"Well-made square profile. The frame took a minor manual adjustment at my local shop easily thanks to the core wire inside."
