Visionstar TF-5470A

Product Code: EOAS-OAVT-3359

Fifty grams on the nose, for refractions that take their time.

Weight is what ends a long refraction early. The TF-5470A is titanium at 50 g, adjusts from 54 to 70 mm, and takes four lenses each side.

The Visionstar TF-5470A is a titanium trial frame. The published data gives an interpupillary adjustment range of 54 to 70 mm, four lenses inserted simultaneously per side, a weight of 50 g, and titanium construction.

Weight is the reason to choose it. A trial frame rests on the nose and ears for the whole of a refraction, and discomfort shows up as a patient shifting, adjusting the frame or hurrying their answers, all of which degrade the result rather than merely annoying them. Taking a dozen grams off a frame is not a marketing detail on a refraction that runs twenty minutes, or on a patient who is elderly, frail or small.

Titanium earns its place here for two properties beyond weight. It resists corrosion well, which matters on an instrument wiped between patients and handled all day with damp hands. It is also among the better-tolerated metals in prolonged skin contact, which is relevant to a frame that presses on the nose and temples, although the specific alloy and any plating are not stated, so Medigear.uk confirms the composition rather than assuming it.

The interpupillary range is narrower than some frames offer, running from 54 rather than 48 mm. For adult refraction that is unremarkable, since most adults fall inside it, but it will not centre correctly on many children. Practices seeing paediatric patients should check that limit before buying this model as their only frame.

Unpublished are the cell diameter, the vertex distance, pantoscopic tilt and temple length adjustment ranges, the alloy grade, any plating, the case and whether a trial lens set is included.

Long refractions are the clearest use. Complex prescriptions, cycloplegic refraction and cases needing repeated checks all keep a frame on the face well beyond a routine test, and weight is felt across that time rather than at the start.

Elderly and frail patients benefit directly, since a lighter frame presses less on thin skin at the nose and temples and is less likely to slip.

Low vision assessment keeps the correction in place while the patient reads, moves and looks around, which is exactly the situation where a heavy frame becomes intrusive.

Domiciliary visits suit a light frame that is carried in a bag alongside everything else, and titanium's corrosion resistance suits equipment that travels in variable conditions.

High-volume clinics gain from a frame that patients tolerate without comment, since time lost to repositioning adds up across a list.

Patients with skin sensitivities are often better served by titanium, subject to confirming the alloy and any plating.

Paediatric refraction is poorly served by the 54 mm lower limit, and practices seeing children need a frame that narrows further.

Occasional use may not justify the cost over a steel frame, since the advantage shows most where the frame is worn often and for long periods.

Fifty grams on the face

A light frame reduces the shifting and repositioning that lengthen a refraction and blur the result.

Rigid as well as light

Titanium's strength-to-weight ratio keeps the frame stiff enough to hold four lenses per side accurately.

Resists corrosion

Suited to an instrument wiped between patients and handled all day with damp hands.

Better tolerated on skin

Titanium is widely used against skin for prolonged contact, subject to confirming alloy and plating.

Four lenses per side

Sphere, cylinder, prism and an auxiliary lens can all be held together without interrupting the test.

Comfortable for frail patients

Less pressure at the nose and temples, where thin skin marks easily.

Suits travelling kit

Light to carry and resistant to the conditions a domiciliary bag sees.

Holds its adjustment

A stiff frame is less likely to drift mid-refraction than a flexible one.

Its narrower range stated plainly

The 54 mm lower limit is identified here as a real constraint for paediatric work, not buried.

Titanium construction

The manufacturer identifies this model as titanium. Alloy grade and any plating are confirmed at order.

The Visionstar TF-5470A is the titanium frame in this range: 50 g, 54 to 70 mm interpupillary adjustment, and four lens cells per side. Weight is the whole argument, and it is a clinical argument rather than a comfort one, because a patient who shifts or hurries under a heavy frame gives a less reliable refraction. Titanium adds corrosion resistance and good skin tolerance, which suit an instrument wiped between patients and worn against the face. The 54 mm lower limit rules it out as a sole frame for paediatric work. Cell diameter, adjustment ranges, alloy grade and case contents are all unpublished, and Medigear.uk confirms each in writing at quotation.

FAQ

Frequently Asked Questions

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

More than it sounds, because the load is carried on the bridge of the nose for the duration of the test. Patients rarely articulate it as weight; they shift, push the frame up, or answer faster to get it over with. On refractions that run long, or with elderly, frail or small patients, a lighter frame produces a steadier result.

Because a trial frame has to hold four lenses per side in an accurate, repeatable position, and stiffness matters as much as weight. Titanium gives a high strength-to-weight ratio, so the frame stays rigid and holds its adjustment while remaining light.

Titanium is generally well tolerated in prolonged skin contact, which is why it is widely used in spectacle frames and implants. However, the specific alloy and any surface plating are not stated here, and sensitivity usually relates to nickel content rather than titanium itself. We obtain the composition in writing if this matters for your patients.

Titanium resists corrosion well, which suits a frame wiped between patients. The manufacturer's approved cleaning agents are not published, though, and repeated alcohol wiping can affect plated surfaces and loosen adjustment mechanisms over time. We obtain the guidance before supply.

Often not. The interpupillary range starts at 54 mm, which will not narrow enough to centre correctly on many children, and a decentred lens introduces unwanted prism. Practices doing paediatric work should ask us about a frame reaching 48 mm instead, or hold both.

Sphere, cylinder, prism and an auxiliary lens such as a pinhole or occluder can all be in place together, so a full prescription can be built and modified without removing lenses mid-test.

Not published. Trial lenses are commonly 38 mm, and the frame must match the set you already own. We confirm the cell diameter before you order.

The frame type suggests so, and the photograph shows adjusters at the temples and bridge, but the ranges are not published. We confirm what adjusts and by how much at order.

Not stated. Trial frames are often supplied cased, with lenses sold separately. We confirm exactly what is included at quotation.

It weighs less and resists corrosion better, and it usually costs more. Where a frame is used occasionally, the difference may not justify the price. Where it is used all day, or for long refractions, it generally does.

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 adjustment wheels still hold their setting, since a frame that drifts mid-refraction gives a wrong answer rather than an obvious fault. Keep the cells clear of lens debris and store it cased. Typical warranty is 12 months, confirmed at quotation.
