The CHARMANT Eyeglasses CH12135 BK are a premium Japanese-engineered titanium optical frame that reflects CHARMANT’s signature philosophy of ultra-lightweight comfort, refined minimalist aesthetics, and precision craftsmanship. Designed for users who prefer elegant everyday eyewear with a professional appearance, this model combines durability, ergonomic fit, and understated luxury.

The CH12135 features a full-rim rectangular / softly squared silhouette with clean modern contours that provide a balanced and sophisticated look. The design follows CHARMANT’s minimalist styling approach, emphasizing lightweight wearability and timeless elegance rather than oversized or fashion-heavy detailing.

The “BK” color code refers to a classic black finish, giving the frame a sleek and versatile appearance suitable for both formal and casual use. Depending on lighting and production variation, the finish may appear as matte black or polished black with subtle metallic titanium accents.

Crafted from lightweight titanium construction, the frame is engineered for exceptional durability, flexibility, and hypoallergenic comfort. CHARMANT is globally respected for its titanium eyewear expertise, and models in the CH12xxx series are especially appreciated for their barely-there feel and long-term ergonomic comfort. Titanium construction also offers corrosion resistance and strength while keeping the frame extremely lightweight.

The frame typically incorporates:

• Adjustable silicone nose pads for personalized comfort
• Slim ergonomic skull temples for stable everyday wear
• Lightweight hinge construction designed for flexibility and reduced pressure

These ergonomic features help evenly distribute weight across the face, making the CH12135 ideal for prolonged office work, reading, driving, or extended screen use.

The rectangular lens geometry provides excellent compatibility with:

• Single vision lenses
• Reading lenses
• Bifocal lenses
• Progressive lenses

Typical sizing for models in the CH121xx titanium series is approximately 52–17–135 mm to 54–17–140 mm, placing the frame in a medium-fit category suitable for many adult face shapes.
