Visionstar TF-B

Product Code: EOAS-OAVT-3419

The same adjustable frame in every room, bought by the carton.

Buying trial frames one at a time leaves a group with a mix of models. The TF-B is a PD-adjustable frame supplied in cartons of fifty, weighing about 150 g packed.

The Visionstar TF-B is a PD-adjustable trial frame, one of three models on a shared sheet with the TF-BT and TF-S. Unusually, the published data describes how the frame is packed rather than how it performs: a unit gross weight of 0.15 kg, a unit size of 18 × 9.5 × 6 cm, fifty pieces to a carton, a carton gross weight of 79 kg, and a carton size of 47 × 36 × 30 cm.

Two of those figures need care. The unit weight is a gross figure, which includes packaging, so the frame itself weighs somewhat less than 150 g; the net weight is not stated. And the carton weight does not add up: fifty units at 0.15 kg each total 7.5 kg, so 79 kg is almost certainly a typographical error for 7.9 kg. The carton rows also sit only under the TF-BT column on the sheet, so whether they apply equally to the TF-B needs confirming.

The photograph shows a conventional adjustable trial frame: a black body, a top bar carrying an interpupillary adjustment knob, silver cells with printed scales around their rims, and temples with sliding adjusters. That is the familiar layout of a frame that sets PD per patient rather than being chosen from fixed sizes.

The practical case for the TF-B is supply. Being available by the carton suits organisations that need many identical frames at once: training colleges equipping a teaching clinic, practice groups standardising across branches, and hospital departments replacing mixed stock. Identical frames mean every clinician and student works with the same controls in every room.

Unpublished are the interpupillary range, lenses per cell, net frame weight, cell diameter, vertex and tilt adjustment, material, and whether the scales are axis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

Optometry training colleges are the clearest fit. A teaching clinic needs many identical frames so every student learns on the same controls, and carton supply makes that practical in a single order.

Practice groups standardising across branches benefit from identical equipment in every room, which reduces errors as clinicians move between sites and simplifies replacement.

Hospital eye departments replacing mixed stock can move to a single adjustable model, making training, maintenance and cleaning procedures consistent.

Locum-heavy practices gain from standard kit, since visiting clinicians find the same frame wherever they work.

Individual practices can still buy a single frame, and the adjustable design suits general adult refraction once the PD range is confirmed.

Domiciliary teams equipping several clinicians at once benefit from identical kits in every bag.

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.

Available by the carton

Fifty identical frames per carton suit organisations equipping many rooms at once.

The same kit everywhere

Clinicians and students find the same controls in every room, which reduces mistakes.

Adjustable PD

The frame is set for each patient rather than chosen from fixed sizes.

Simpler maintenance

One model across a site means one set of spares, one cleaning procedure and one training routine.

Suits teaching clinics

Students learn on identical equipment, so instruction transfers directly from bench to bench.

Individual supply too

Practices needing a single frame can buy one without a bulk order.

Conventional layout

A top-bar PD adjuster, scaled cells and sliding temples follow the familiar adjustable frame design.

Light to handle

Around 150 g packed, so the frame itself weighs less than that.

Data issues flagged

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

PD-adjustable design

A knob on the top bar adjusts interpupillary distance, as shown in the photograph.

Scaled cells

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

Sliding temple adjusters

Temples with visible sliders. Adjustment range confirmed at order.

Black body

A dark frame body with silver cells.

Unit gross weight

0.15 kg, including packaging.

Unit size

18 × 9.5 × 6 cm.

Carton quantity

50 pieces, per the sheet. Applicability to the TF-B confirmed at order.

Carton size

47 × 36 × 30 cm, per the sheet.

Carton weight

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

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-B is a PD-adjustable trial frame supplied individually or in cartons of fifty, with a conventional layout of top-bar adjuster, scaled cells and sliding temples. The published data is logistical rather than optical, which shapes its best use: training colleges, practice groups and hospital departments that want identical frames in every room. Before ordering, two things need settling. The interpupillary range and lens capacity are not published at all, and the carton weight of 79 kg cannot be right for fifty frames at 0.15 kg each, so it is almost certainly 7.9 kg. Medigear.uk confirms the full specification and the carton figures 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.

Mostly how the frame is packed and shipped. The sheet gives a gross unit weight, a unit size and carton figures, but no interpupillary range, lens capacity or net weight. Medigear.uk obtains the optical specification before supply.

Because it is inconsistent. Fifty frames at 0.15 kg gross each come to 7.5 kg, so a carton of 79 kg is not possible for this product. The figure is almost certainly 7.9 kg, allowing for the carton itself. We confirm it rather than repeat an error.

No. It is a gross weight, which includes the individual packaging. The frame's own weight is lower and is not published. We obtain the net figure, which is what matters on a patient's face.

Not stated on the sheet, which is the most important gap for a PD-adjustable frame. We confirm the range before supply so you know which patients it will centre on.

Not stated. Adjustable trial frames commonly take three or four per side, and that decides whether a full prescription can be built at once. We confirm the figure before you order.

Organisations needing many identical frames: optometry training colleges, practice groups standardising across branches, and hospital departments replacing mixed stock. A single frame is also available for individual practices.

Because clinicians move between rooms and students move between clinics. Controls in the same place on every frame reduce errors and speed up each refraction, and a standard kit is easier to maintain and replace.

The sheet places them under the TF-BT column only. They may apply to the whole range, but we confirm the packing quantity and carton size for the TF-B specifically before you order in bulk.

The photograph shows sliding adjusters on the temples and a knob on the top bar, but the adjustment 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 and temple sliders hold their settings, keep the cells free of lens debris, and store frames cased. In a teaching setting, check adjusters more often, since frames are handled heavily. Typical warranty is 12 months, confirmed at quotation.
