Visionstar sells the PL-T9 as progressive test lenses: progressive multifocal trial lenses with additions from +1.00 to +3.00 D and pupillary distance options of 58, 60, 62, 64 and 66 mm. That is the whole of the published specification. The datasheet does not state how many lenses the set contains, the addition steps, lens diameter, corridor length, fitting height or lens material, or whether frames are included. The photograph shows a zipped case holding five light-blue frames, a row of lenses and a ruler-like item in the lid.

The set exists for the patient's first experience of a progressive lens. Seated with a test lens in place, a presbyope can look into the distance, lower the eyes through the corridor to read, and turn the head to meet the blurred periphery that every progressive design has. That tells the practitioner and the patient something before an order is placed, and sets honest expectations of the one to three weeks that adaptation commonly takes. It does not reproduce those weeks, and no published evidence shows that a short trial predicts who will adapt.

The five PD values suggest that the lenses or frames are made for fixed pupillary distances, which keeps the corridor aligned with each pupil. The datasheet does not say how the patient's distance prescription is combined with the test lens.

Optical practices and dispensing areas are the natural setting. A presbyope who has worn single-vision lenses, or who has only ever used ready-made readers, often has no idea what a progressive lens looks like from behind. Placing a test lens with the right addition in front of each eye, and letting them look at a distance chart, a screen at arm's length and a page in the hand, gives them a first-hand sense of the corridor and the peripheral blur before the order is placed.

Consultations where the choice is open use the set to compare options in the patient's own experience. Someone who spends long hours at a computer may find the intermediate zone narrow for that work and choose a different solution, and a patient who drives a great deal can check how the distance zone feels when the head moves.

Practices following up a non-tolerant wearer can use a test lens to separate a design problem from a prescription problem. Published data on non-tolerance show prescription causes to be the most frequent, followed by dispensing causes, so a trial alongside a check of the addition helps direct the next step.

Training for dispensing opticians and optical assistants benefits from a physical example of progressive optics, including how the corridor narrows and how fitting height affects what the wearer sees.

Hospital eye services and low vision clinics may use the set to show patients the option, though the addition range stops at +3.00 D.

The set is less suited to demonstrating a named commercial design, or to patients outside the 58 to 66 mm PD options. Institutional buyers commonly ask for evidence of conformity. The conformity documentation those procurement routes require is issued by the manufacturer and provided by the seller.

A First Look Before Ordering

The patient experiences progressive vision in the practice before any spectacles are made, which makes the conversation about expectations concrete.

Additions Across the Common Presbyopic Range

Additions from +1.00 to +3.00 D span the powers most presbyopes are prescribed.

Fixed PD Options

Five PD values from 58 to 66 mm in 2 mm steps help keep the progressive corridor in front of the pupil during the trial.

A Physical Teaching Example

Trainees can see and handle progressive optics, which helps explain corridor width, peripheral blur and the role of fitting height.

Useful in Non-Tolerance Reviews

A test lens helps separate a design question from a prescription question when a wearer has struggled with progressives.

Portable Zipped Case

The photograph shows a zipped case holding frames and lenses together, suited to moving between a consulting room and a dispensing desk.

No Electrical Upkeep

The set has no electrical parts, needs no mains supply and never enters a portable appliance testing schedule.

Honest Expectation-Setting

Seeing the periphery of a progressive before ordering lets the patient make an informed choice, which is the part of adaptation a practice can influence at the outset.

Progressive Multifocal Test Lenses

The lenses are described as progressive multi-focus trial lenses.

Addition Range

Additions from +1.00 to +3.00 D. Step size and quantities are not published.

PD Options

Pupillary distances of 58, 60, 62, 64 and 66 mm.

Frames

The photograph shows five light-blue frames in the case and trial frames with protractor scales and adjustment knobs. Whether frames are included is not stated.

Lens Count

Not published. The photograph shows a row of about twenty lens-like pieces.

Lens Design Parameters

Corridor length, fitting height, inset and lens diameter are not published.

Distance Zone

Whether the test lenses carry distance power is not stated.

Lens Material

Not published.

Lid Items

The photograph shows a ruler-like item and a blue clip-like item in the lid. Neither is described.

Case

A zipped case with a fitted tray and lid pocket, shown in the photograph. Dimensions and weight are not published.

Power Source

None. The set has no electrical parts.

The PL-T9 lets a presbyope look through a progressive lens before the spectacles are ordered, with additions from +1.00 to +3.00 D and PD options from 58 to 66 mm. It helps set honest expectations, though no evidence shows that a short trial predicts adaptation. The datasheet leaves the contents, addition steps, frame arrangement and lens design unstated, so those questions come first in any enquiry. Medigear.uk lists the PL-T9 for business buyers worldwide and can arrange delivery, familiarisation and service cover. Request the packing list, addition steps, lens diameter, frame details, case dimensions and the declaration of conformity from the seller at quotation.

FAQ

Frequently Asked Questions

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

It lets a presbyopic patient look through a progressive addition lens before committing to spectacles. The practitioner places a test lens with the appropriate addition in front of the eye, and the patient can try distance, intermediate and near viewing along the corridor. It is used in dispensing and in consultations where a patient is unsure whether progressives, bifocals or separate reading spectacles will suit them. The datasheet names the product and its ranges but no specific procedure.

The datasheet does not say. The photograph shows a zipped case with five light-blue frames in the upper tray, a blue item beside them, a row of about twenty lens-like pieces along the bottom and a ruler-like item and a blue clip-like item in the lid. Two further images show light-blue trial frames with protractor scales and adjustment knobs holding lenses. Treat every one of those items as unconfirmed until the seller provides a written packing list.

The datasheet gives an addition range of +1.00 to +3.00 D, written as +100 to +300. It does not give the step size or the number of lenses per addition. Progressive test sets are commonly made in 0.25 D steps, but that is not stated here, so confirm the steps and whether each addition is supplied as a right and left pair.

The datasheet lists 58, 60, 62, 64 and 66 mm without explaining them. The most likely arrangement is that frames or lens mounts are built for those fixed distances, so that the progressive corridor sits in front of each pupil. That covers much of the adult range in 2 mm steps. Patients whose PD falls outside 58 to 66 mm, or whose two monocular PDs differ noticeably, will not be matched exactly. Ask the seller how PD is set and whether monocular values can be accommodated.

The datasheet does not say whether the test lenses carry any distance power or are plano in the distance zone. If they are plano, the patient's distance correction must be added in front of or behind the test lens, which requires frames with spare cells. The frames shown in the photograph appear to have more than one cell, but the number is not stated. Confirm this before order, because a progressive trial without the correct distance prescription can mislead the patient about how clear the distance zone will be.

No evidence shows that it does. Adaptation to progressive lenses commonly takes one to three weeks, and a small proportion of wearers never tolerate them. A UK practice study of 3,091 eye examinations found a non-tolerance rate of 1.8%, with presbyopes accounting for 88.1% of cases. Prescription-related causes made up 61.0% and dispensing-related causes 22.0%. Research has linked successful adaptation to vergence facility and the rate of phoria adaptation, which a short trial does not measure. What the trial does offer is an informed patient who knows what the periphery of a progressive lens looks like.

None beyond the addition range and PD options. Corridor length, fitting height, inset, lens diameter and lens material are all unpublished. Those details decide whether the test lens resembles the design a patient will eventually receive. Ask the seller for them and explain to the patient that a test lens represents progressive vision in general, not a specific commercial lens design.

BS EN ISO 9801:2009 covers trial case lenses, and the manufacturer does not state whether it applies it to progressive test lenses. For finished progressive spectacle lenses the power tolerances sit in BS EN ISO 8980-2, which this page cites as the closest applicable reference. If frames are included, BS EN ISO 12867 is the trial frame standard. Under UK MDR 2002 the set is typically Class I, or higher, use-dependent, confirmed against the declaration of conformity at order. The declaration is issued by the manufacturer and provided by the seller. Conformity requirements differ by destination market, and the seller confirms what applies where the unit is going.

In the UK, the addition forms part of a prescription issued after a sight test by a registered optometrist or registered medical practitioner under the Opticians Act 1989. Demonstration and advice on progressive lenses commonly involve dispensing opticians, who are also registered with the General Optical Council. Other countries set their own rules on who may prescribe and dispense.

The set has no electrical parts, so it sits outside electrical safety and portable appliance testing, and in a UK workplace PUWER 1998 applies as it does to any work equipment. Frames rest on the patient's face and nose, so cleaning between patients matters. Disinfectant compatibility for the lenses and frames is not published, so ask for the manufacturer's cleaning instructions and replacement pricing for single lenses and frames.

A practice that needs additions above +3.00 D will find the range stops there. Patients with a PD outside 58 to 66 mm, or with markedly unequal monocular PDs, will not be matched exactly. A dispenser who wants to demonstrate a specific branded lens design will find that a generic test lens cannot represent it.
