Overview — Size, Fit, and Customization
Get a precise fit across optical frames and metal sunglasses with clearly defined dimensions: lens width, bridge width, and temple length. In‑house design and manufacturing keep measurements consistent across semi‑titanium, pure titanium, TR, Ultem, and acetate. We also offer tailored adjustments for comfort and style. Examples include titanium eyewear 70129 (50‑18‑143) and the Korean circle frame Cailin Kelien 81101 (50‑21‑149), both designed for balanced wear.
Key Measurements Explained
- Lens width (e.g., 50 mm): Shapes visual coverage and overall proportion. Optical styles commonly range from 46–54 mm; sun styles often run wider.
- Bridge width (e.g., 18 mm): Affects nose contact and pressure. Metal and titanium with adjustable pads allow fine tuning; acetate bridges rely on ergonomic shaping.
- Temple length (e.g., 143 mm): Determines ear reach and stability. Common lengths are 135–150 mm. Metal/titanium permit micro‑adjustments; TR/Ultem add lightweight flexibility.
How to Measure Your Current Frame
Check the numbers stamped inside the temple (e.g., 50‑18‑143). Or measure with a millimeter ruler across the lens, bridge, and temple. Confirm symmetry, pad alignment, and that temples rest comfortably behind the ears. This simple method helps you match proven dimensions to new styles.
Practical Sizing Tips
- Measure on a flat surface with straight temples and centered pads.
- Compare against a size chart.
- Consider material feel—titanium may sit lighter than acetate at the same numbers due to weight and flexibility.
Size Categories — Small, Medium, Large
- Small (compact fit): Typically lens 46–49 mm, bridge 16–18 mm, temple 135–140 mm. TR/Ultem and semi‑titanium offer lightweight stability in compact profiles.
- Medium (balanced fit): Typically lens 50–52 mm, bridge 17–19 mm, temple 140–145 mm. Pure titanium combines strength with low weight; acetate adds sculpted contours.
- Large (wide coverage): Typically lens 53–56 mm, bridge 18–21 mm, temple 145–150 mm. Metal sunglasses and larger optical styles increase coverage with adjustable pads for secure retention.
Materials and Use Cases
- Titanium (semi and pure): High strength at low weight with precise sizing from small to large. Adjustable temples and pads help maintain comfort during long wear.
- Acetate: Structured feel and expressive color, often in medium and large formats. Ergonomic bridges and sculpted temples distribute pressure evenly.
- TR/Ultem: Flexible and lightweight, ideal for small to medium sizes. Reduces ear pressure while maintaining shape in daily movement.
- Metal sunglasses: Pair rim strength with adjustable pads and wider lenses for outdoor coverage.
Fit and Comfort Guidelines
A correct size centers the eyes in the lens area and rests evenly on the nose. Temples should touch lightly behind the ears. Adjust pads and temple angles to keep the frame stable during movement. Choose fixed acetate bridges for sculpted support or metal/titanium pads for micro‑adjustments. Refine temple bend and end‑tips to follow ear contours and reduce pressure points.
Product Highlights — Size Examples

FAQs
- What size is right for me? Start by matching your current numbers, or begin with a medium and fine‑tune bridge and temple length.
- Can temple length be customized? Yes. Length and angle can be selected or adjusted across materials to keep a balanced fit.
- What’s the difference between optical and sun fit? Optical frames target precise alignment with typically narrower lenses, while sun styles use larger lenses and adjustable pads for outdoor stability.
