Charmant Japanese Made Eyewear Collection

Charmant Japanese Made produces eyeglasses in Japan using standard optical manufacturing processes. The frames are made from materials like stainless steel, titanium alloys, and acetate plastics—common in Japanese eyewear production for their weight-to-strength ratios and corrosion resistance. Production includes CNC machining for metal components, injection molding for plastic parts, and hand assembly for hinge installation and temple alignment.

Japanese optical factories typically maintain tighter tolerances than mass-market facilities, which affects how temples align, how nose pads sit, and how consistently frames hold their shape. Charmant Japanese Made frames reflect these manufacturing standards, with measurements held to within 0.5mm variance and hinge tension calibrated for 20,000+ open/close cycles.

Women's Eyeglasses

Women's frames in this collection include smaller lens widths (typically 50-54mm) and narrower bridge measurements (16-19mm) to fit proportionally smaller facial dimensions. Temple lengths run 135-145mm. Frame shapes include modified rectangles, soft cat-eyes, and rounded squares.

Construction uses either full acetate rims or metal semi-rimless designs with nylon cord securing the bottom lens edge. Acetate frames are cut from cellulose acetate sheets, then tumbled and polished. Metal frames use stainless steel or nickel-silver alloys with electroplated finishes in gunmetal, rose gold, or brushed silver. Nose pads on metal frames are adjustable silicone or PVC, allowing optical staff to customize the fit.

Temple tips use either matching acetate or rubberized sleeves for grip. Spring hinges are standard on most models, allowing temples to flex outward beyond 90 degrees without damage.

Men's Eyeglasses

Men's frames feature larger lens widths (54-58mm) and longer temple lengths (140-150mm) to accommodate broader faces and wider head circumferences. Bridge widths run 17-21mm. Shapes lean toward rectangles, squared ovals, and navigator-inspired designs.

Frame materials include beta-titanium (a titanium alloy with added aluminum and vanadium for flexibility), stainless steel, and thick acetate. Beta-titanium frames are laser-welded at joints rather than soldered, creating stronger connections. Acetate frames in this category use thicker stock (5-7mm) for a more substantial look and increased durability.

Hinge mechanisms include five-barrel hinges (more durable than three-barrel) and spring-loaded hinges. Temples are often reinforced with internal metal cores on acetate frames to prevent warping. Adjustable nose pads allow for vertical and horizontal positioning to prevent frames from sliding.

Unisex Eyeglasses

Unisex frames use mid-range measurements (52-55mm lens width, 17-19mm bridge, 140-145mm temples) that fit a broader range of face sizes. Shapes include round, oval, and balanced rectangular designs without strong masculine or feminine styling cues.

These frames often use combination construction—metal front rims with acetate temples, or acetate fronts with metal temple cores. This approach balances weight, durability, and aesthetic variety. Color palettes stick to neutrals: black, tortoise, navy, gray, and clear crystal acetates, plus silver, gunmetal, and bronze metals.

Hinge placement and temple curvature are engineered for average ear positioning, though optical adjustments can customize fit. Lens shapes are designed to accommodate progressive lenses with adequate vertical height (minimum 30mm) for the reading corridor.
