INJECTION / PLASTIC OPTICAL FRAMES
Injection-Molded Optical Frames Designed for Consistent Prescription Fit
Injection-molded optical frames built for dimensional accuracy, stable lens support, and long-term program scalability in prescription eyewear.
Frames only. Lenses are not included.
Overview
What Injection Optical Frames Are Built For
Injection optical frames are produced through precision molding processes that emphasize dimensional repeatability and structural reliability.
Rather than focusing on material texture, these frames are selected for prescription programs where lens fit accuracy, batch consistency, and predictable production are essential.
They are commonly used in long-running optical collections that prioritize stability over seasonal variation.
Advantages
Advantages for Prescription-Focused Programs
Dimensional Consistency
Mold-controlled geometry supports reliable lens installation across batches.
Stable Frame Structure
Designed to maintain shape during daily wear and routine handling.
Production Predictability
Injection processes support clear timelines and repeatable outcomes.
Program-Level Cost Control
Suitable for long-term optical lines with planned volumes.
Material Comparison
Injection Optical Frames Compared to Other Materials
Material selection in optical frames should follow prescription demands and supply expectations.
| Feature | Injection Plastic | TR90 | Acetate | Metal |
|---|---|---|---|---|
| Lens mounting stability | High | Medium | Medium | High |
| Shape repeatability | High | Medium | Medium | Medium |
| Flexibility | Low–Medium | High | Medium | Low |
| Visual emphasis | Clean and uniform | Minimal and functional | Textured and expressive | Defined and structural |

Optical Fit
Optical Fit Built on Dimensional Accuracy
Prescription reliability depends on frame geometry that remains stable before and after lens installation.
Lens rim dimensions planned for consistent mounting
Frame rigidity supports prescription accuracy
Bridge geometry maintains alignment under load
Reduced risk of post-assembly distortion
Designed to minimize refitting and remakes
Wear Comfort
Everyday Wear with Structural Confidence
Comfort in injection optical frames comes from predictable balance rather than flexibility.
A stable structure helps frames sit consistently throughout the day, supporting users in school, work, and daily routines.
This makes injection frames a practical choice for frequent, long-hour wear.
Balanced front-to-temple weight
Stable positioning during daily movement
Suitable for repeated on/off use
