Visionstar TF-5608

Product Code: EOAS-OAVT-3363

Eight sizes, from fifty-six to seventy.

The patients who fall outside a set are the ones who need it most. The TF-5608 runs from 56 to 70 mm in eight steps, each frame colour-coded and holding four lenses per eye.

The Visionstar TF-5608 is a boxed set of eight fixed-pupil trial frames. The published data lists interpupillary sizes of 56, 58, 60, 62, 64, 66, 68 and 70 mm, four lenses inserted simultaneously per side, and a weight given as 65 kg, which is plainly a typographical error for 65 g. Medigear.uk confirms the correct figure before supply.

A fixed-pupil frame has no interpupillary adjustment. The optical centres sit at one spacing, so the clinician selects the frame matching the patient's measurement rather than setting a mechanism, which removes both the setup time and the risk of refracting someone at the previous patient's spacing.

The span is what distinguishes this set. Eight sizes reach 56 mm at the narrow end and 70 mm at the wide end, which covers a wider range of adults, some older children and patients at both extremes of the adult distribution. Adding two frames to a six-frame set sounds marginal until a patient measures 55 or 69 mm, at which point the alternative is fitting them to a frame that is 2 or 3 mm out and accepting the induced prism.

The steps remain 2 mm, so patients between sizes are still fitted to the nearer frame. The wider span changes who is covered at the ends, not the resolution in the middle.

The photograph shows the frames colour-coded and held in a fitted tray, which is how the approach saves time: the right size is identified by colour and lifted out.

Unpublished are the cell diameter, the frame material, the tray construction, whether individual sizes can be reordered, and whether a trial lens set is included.

Broad patient populations are the clearest fit. A practice seeing a wide mix of adults will meet interpupillary distances at both extremes, and the outer frames stop those patients being the ones fitted least accurately.

Vision screening benefits from the same speed as any fixed-pupil set, with fewer patients falling outside the range.

Occupational health assessments cover working-age adults of every build, which is exactly the population where the outer sizes get used.

High-volume clinics gain from the removal of per-patient setup, and from the reduced chance of reaching for a frame that does not fit.

Teaching clinics can demonstrate the effect of decentration across a full range of sizes, including the extremes students rarely see.

Second sets suit practices that already hold an adjustable frame, covering routine cases quickly while the adjustable frame handles complex ones.

Paediatric refraction remains outside this set, since 56 mm reaches only some older children.

High prescriptions still belong in an adjustable frame, where centration is set exactly rather than approximated to the nearer 2 mm.

Covers both extremes

Sizes at 56 and 70 mm reach patients that narrower sets leave to approximation.

Nothing to set

A fixed centre cannot drift mid-refraction or be left at the previous patient's spacing.

Chosen by colour

Identifying the right frame by colour is quicker and less error-prone, particularly across eight of them.

Repeatable centration

The optical centres are in the same place every time, which suits standardised testing.

Four lenses per side

Full prescriptions can still be built despite the simpler construction.

Light to handle

At 65 g per frame, the set is easy to carry and comfortable to wear.

Ordered in a tray

Frames return to a fixed place, so the next one needed is where it should be.

Fewer patients turned away from the set

A wider span means the adjustable frame is reached for less often.

Its resolution stated plainly

The steps remain 2 mm, so the extra frames widen coverage without refining it.

Eight fixed interpupillary sizes

56, 58, 60, 62, 64, 66, 68 and 70 mm, in 2 mm steps.

Colour-coded frames

Each size in a distinct colour for quick identification.

Four lenses per side

Four cells each side accept lenses simultaneously.

65 g per frame

Corrected from the published figure, which reads 65 kg in error.

Fitted tray presentation

Supplied as a set in a tray, as shown in the photograph. Construction and dimensions are confirmed at order.

No interpupillary adjustment

Fixed optical centres by design.

Cell diameter

Not published. Confirmed against your trial lens set at order.

Frame material

Not specified. Confirmed at order.

Individual size reordering

Not stated. Availability confirmed at order.

Tray dimensions

Not published. Confirmed at order for storage and transport planning.

Trial lens set

Not stated as included. Confirmed at quotation.

Coverage limits

Nothing below 56 mm or above 70 mm; patients between steps fitted to the nearer size.

The Visionstar TF-5608 is the wider fixed-pupil set: eight frames covering 56 to 70 mm in 2 mm steps, colour-coded in a fitted tray, each taking four lenses per side. The extra sizes sit at the ends of the adult range, which is precisely where a narrower set forces a compromise, and the compromise falls on patients whose anatomy is already unusual. Nothing is adjusted, so there is no setup time and no risk of inheriting the previous patient's spacing. Children below 56 mm and high prescriptions needing exact centration still require an adjustable frame. The published weight of 65 kg is an error for 65 g, and Medigear.uk confirms that alongside cell diameter and tray dimensions. Contact the Medigear.uk team for pricing.

FAQ

Frequently Asked Questions

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

Because the manufacturer's sheet contains a typographical error. A trial frame weighing 65 kg is not possible; the figure is 65 g. We confirm the correct weight in writing rather than reproducing the error.

It depends on your patients. The additional frames sit at 56 and 70 mm, the ends of the adult range, and they matter only when someone measuring near those figures presents. If that happens regularly, the alternative is accepting a 2 to 3 mm decentration on exactly the patients whose anatomy is already unusual.

At the margin. A 56 mm frame reaches some older children, but most children measure below that, so paediatric refraction still needs an adjustable frame reaching into the forties. This set extends adult coverage rather than crossing into paediatric work.

They are fitted to the nearer frame, which is unchanged from a narrower set, since the steps are 2 mm throughout. At low prescriptions the induced prism is negligible; at high powers an adjustable frame is the better choice.

For identification. Picking by colour is faster and less error-prone than reading a number on each frame, which matters more with eight frames in a tray than with fewer.

Not stated. Middle sizes see far more use than 56 or 70 mm and wear out sooner, so the ability to replace one frame rather than the set is worth establishing. We confirm availability.

Only if the cell diameter matches. Trial lenses are commonly 38 mm, but the diameter is not published here. We confirm it against the set you already own before you order.

Not specified. Fixed-pupil frames are typically simpler and lighter than adjustable ones, consistent with the published weight, but material and finish are confirmed at order.

The tray dimensions are not published. Eight frames take more space than a smaller set, which matters if it lives in a drawer or travels in a domiciliary bag. We obtain the figures.

Vision screening, occupational health, high-volume clinics and teaching, particularly where the patient population is broad enough that the outer sizes get used. It also works as a second set alongside an adjustable frame.

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.

Keep the cells clear of lens debris, check the sides and bridges for distortion, since a bent fixed frame cannot be adjusted back into true, and return each frame to its place in the tray. Typical warranty is 12 months, confirmed at quotation.
