The Visionstar TF-BT is a PD-adjustable trial frame, one of three models on a shared sheet with the TF-B and TF-S. As with its siblings, the published data describes packing rather than performance: a unit gross weight of 0.15 kg, a unit size of 16.5 × 9 × 5.5 cm, fifty pieces to a carton, a carton gross weight of 79 kg, and a carton size of 47 × 36 × 30 cm. On the sheet, the carton rows sit directly under this model's column, so they apply most clearly to the TF-BT.

Two figures need care. The unit weight is gross, including packaging, so the frame itself weighs less than 150 g. And the carton weight is inconsistent: fifty units at 0.15 kg total 7.5 kg, so 79 kg is almost certainly a typographical error for 7.9 kg. Medigear.uk confirms both before supply.

The photograph shows a gunmetal-grey frame with a shaped brow bar across the top, cells with printed scales, and broad, flat paddle-shaped temples. Wide temples spread contact over a larger area behind the ear, which helps a frame sit steadily and comfortably through a long refraction.

The compact packed size is the practical point. At 16.5 × 9 × 5.5 cm, the TF-BT has the smallest unit dimensions on its sheet, which matters to practices holding spare frames for several rooms, domiciliary teams carrying kit in a car, and anyone ordering by the carton, where fifty frames need to be stored before they are distributed.

Unpublished are the interpupillary range, lenses per cell, net frame weight, cell diameter, vertex and tilt adjustment, material, and whether the scales are axis calibration.

Practices holding spares for several rooms gain most from the compact pack, since a stock of frames takes less cupboard space before and after distribution.

Domiciliary teams carrying equipment by car benefit from a smaller unit, particularly when each clinician keeps a spare frame in the kit.

Bulk buyers such as training colleges and practice groups can store a carton of fifty more easily before rolling frames out to rooms or students.

Long refractions suit the broad temples, which spread pressure behind the ear and help the frame stay still and comfortable.

Hospital departments replacing stock can standardise on a frame that is both adjustable and economical to store.

Clinicians who prefer a grey metallic look over a black frame have an alternative within the same family.

Paediatric work depends on the lower end of the unpublished PD range, which we confirm before recommending the frame for children.

Complex prescriptions depend on the lens capacity, also unpublished, which we establish before supply.

The most compact pack on its sheet

At 16.5 × 9 × 5.5 cm per unit, the TF-BT takes less storage than its siblings.

Easier to store in bulk

A carton of fifty occupies less space while it waits to be distributed.

A smaller unit fits more easily into a domiciliary bag.

Broad, flat temples

Wide temples spread contact behind the ear for a steadier, more comfortable fit.

Brow bar front

A shaped bar across the top, as shown in the photograph.

Gunmetal finish

A grey metallic look, distinct from the black models in the range.

PD-adjustable

Set for each patient rather than chosen from fixed sizes.

Carton supply

Available fifty to a carton for bulk buyers, or singly.

Data issues flagged

The carton weight error and missing optical specification are identified here before ordering.

Published as 79 kg, almost certainly 7.9 kg. Confirmed in writing.

Brow bar

A shaped bar across the top of the frame. Function confirmed at order.

Broad temples

Wide, flat paddle-shaped temples, as shown in the photograph.

Gunmetal finish

Grey metallic colouring.

Scaled cells

Printed markings around each rim. Axis calibration confirmed at order.

Interpupillary range

Not published. Confirmed before supply.

Lenses per cell

Not published. Confirmed before supply.

Net frame weight

Not published. Obtained before supply.

The Visionstar TF-BT is a PD-adjustable trial frame with the most compact pack on its sheet, 16.5 × 9 × 5.5 cm per unit, shipped fifty to a carton, in a gunmetal finish with a brow bar and broad flat temples. The compact size suits practices storing spares for several rooms, domiciliary teams and bulk buyers, and the broad temples help it sit steadily through a long refraction. The published data is logistical rather than optical, so the interpupillary range, lens capacity and net weight all need confirming, and the carton weight of 79 kg cannot be right for fifty frames at 0.15 kg, so it is almost certainly 7.9 kg. Medigear.uk confirms each in writing. Contact the Medigear.uk team for single-unit or carton pricing.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Less storage for the same number of frames. At 16.5 × 9 × 5.5 cm per unit, spares for several rooms fit in a smaller space, a domiciliary bag carries one more easily, and a carton of fifty takes up less room while it waits to be distributed.

Because fifty frames at 0.15 kg gross each come to 7.5 kg, so a carton of 79 kg cannot be right. The figure is almost certainly 7.9 kg once the carton itself is included. We confirm it rather than repeat an error.

No. It is a gross weight including packaging. The frame's own weight is lower and not published. We obtain the net figure, which is what the patient actually feels.

They spread contact over a larger area behind the ear. A wide, flat temple sits more steadily and presses less at any one point than a thin arm, which helps comfort and keeps the frame still during a long test.

The photograph shows a shaped bar across the top of the frame. On adjustable trial frames this usually carries the interpupillary mechanism and stiffens the front. Its exact function here is confirmed at order.

Not stated on the sheet, which is the most important gap for a PD-adjustable frame. We confirm the range before supply.

Not stated. Adjustable trial frames commonly take three or four per side. We confirm the figure before you order.

The sheet gives the TF-BT a smaller unit size and places the carton data under it. The photographs show a gunmetal finish, brow bar and broad temples, where the TF-B is black with thinner adjustable temples. Functional differences are not stated and are confirmed in writing.

Not stated. The photograph suggests an adjustable frame, but the ranges are not published. We confirm what adjusts and by how much.

The photograph shows printed markings around each rim, which usually indicates axis calibration, but the data does not say so. We confirm before you order.

A trial frame is generally a Class I medical device under the UK Medical Devices Regulations 2002. Medigear.uk confirms CE marking, the declaration of conformity and UKCA status at quotation.

Check that the PD adjustment holds its setting, keep the cells free of lens debris, and store frames in their individual packs, which is where the compact size pays off. Typical warranty is 12 months, confirmed at quotation.
