Why Choose Titanium Frames for Eyeglasses?

Titanium is a lightweight, highly flexible metal that provides distinct performance advantages over standard alloy frames:

Flexible and Durable

Titanium frames flex under stress and return to their original shape without bending out of alignment or breaking, ensuring reliable long-term durability.

Featherlight Comfort

At just 8 grams, the THETA frame removes facial pressure points. Titanium frames are roughly 40% lighter than conventional metal or acetate frames, reducing ear and nose bridge fatigue.

Natural Hypoallergenic Properties

Titanium is naturally biocompatible, making it the preferred choice for sensitive skin prone to metallic reactions or irritation.

Advanced Hinge Engineering

By eliminating tiny screws and complex weld points, screwless titanium frames maintain smooth temple action without loose hardware over continuous use. Discover our complete eyewear selection in our online glasses catalog.

FAQs

Are THETA frames suitable for progressive lenses?

Yes. The round lens geometry and 49mm eye size offer sufficient vertical depth for single-vision, bifocal, and progressive prescription lenses.

How does the screwless hinge work?

The screwless hinge uses interlocking titanium components instead of traditional screws, preventing temple arms from loosening over time.

What color options are available for the THETA frame?

The THETA frame is available in five IP ion-plated finishes: Black, Gold, Silver, Blue, and Gray.
