The trial frame holds trial lenses during subjective refraction and lets the examiner fine-tune sphere, cylinder and prism combinations. Independent PD, temple and tilt adjustment ensure comfortable, accurate positioning. A core refraction-room instrument.
What to check before ordering
- Aperture match. Confirm it accepts the trial lens format you already own or are ordering.
- Adjustment. Check which adjustments are provided so the frame suits both adult and paediatric patients.
- Lens cells. Ask how many front and rear cells are available for combined sphere, cylinder and prism work.
- Weight. For long clinics, frame weight is a real comfort factor — ask before bulk ordering.
