Solid everyday frame
The adjustments are smooth and hold their setting, and lens changes are quick. A dependable tool for low-vision and paediatric refraction where a phoropter is impractical.

The TF-A is the budget trial frame of the TF line. Fixed PD scale printed directly on the body, no adjustment mechanism — the simplest possible frame for refraction stations that need stocks per PD rather than per-patient adjustment.

- Fixed PD — one frame per PD point, marked on the body.
- PD scale 52, 54, 56, 58, 60, 62, 64, 66, 68, 70 mm — covers the common adult cohort.
- Individual-box packaging — arrives ready for shelf inventory.
- No moving parts — zero maintenance, zero failure mode.

Customer reviews
4.3· 3 reviewsLightweight and stable
Comfortable enough for patients to wear during a walk-around trial, and the rotating cylinder cell makes axis checks quick. A well-made trial frame.
Peter Vaughan, ODApr 9, 2025
Adjustable and comfortable
The PD and temple adjustments let me seat the frame accurately on most patients, and the cells hold trial lenses securely without slipping. Handy for verifying a refraction outside the phoropter.
