The Visionstar D-910 is an automatic progressive channel lensmeter built for opticians, dispensing labs and hospital eye departments that measure a high volume of lenses each day. Place a lens on the table and it recognises the type on its own and returns a reading in around 0.1 seconds, with no mode switching or menu hunting in between — a full pair takes little longer than the time needed to reposition the frame, which matters most at collection, when a patient is waiting and the check needs to be thorough rather than quick. Measurement covers sphere to 25 dioptres, cylinder and addition to 9.99 and prism to 15 cm/m, a range that handles everyday dispensing as well as the awkward jobs at either end of the prescription book, so high-power and prismatic work does not have to be sent elsewhere to be verified. Alongside power it reports PD, PH and progressive channel length, and that last figure is what separates it from a basic auto-lensmeter: rather than simply confirming distance and near readings, it maps the corridor itself, making it as useful for investigating a non-adapting progressive wearer as it is for signing off incoming lab work or running outgoing quality control on freeform lenses. The tilting colour display angles to suit a seated or standing operator and stays readable across a dispensing bench or a busy clinic room, the integrated marking unit lets you mark centre and axis for layout, glazing or blocking without moving the lens, and the weighted base keeps the footprint small enough for a crowded practice bench or workshop counter. Supplied new by Medigear, a certified professional seller, CE and ISO certified with global shipping; Medigear.uk confirms the full configuration, including display specification, measurement increments, memory, printing and connectivity options, on request.

Sphere, Cylinder and Addition

Sphere reads from 0 to plus or minus 25, with cylinder and addition each from 0 to plus or minus 9.99, and axis across 0 to 180 degrees in 1 degree steps.

Hundredth Resolution Available

All three powers are selectable at 0.01, 0.12 or 0.25 steps, so a lens can be verified at a hundredth where a tolerance question actually needs settling properly.

Automatic Lens Recognition

Single, progressive and automatic recognition modes are provided, so the instrument identifies the lens type instead of the operator having to declare it first.

PD, PH and Channel Length

Pupillary distance, pupillary height and progressive channel length are all measured, with PD reading from 40 to 90mm in 0.5mm steps across the range.

Ultraviolet and Green Light

The wavelengths of ultraviolet and green light are measured simultaneously, which the manufacturer lists among the principal capabilities of this instrument.

Prism and Contact Lenses

Prism reads 0 to 15 cm/m in either X-Y or P-B form, cylinder is presentable three ways, and both soft and hard contact lenses can be measured on it.

Fast Reading and Wide Acceptance

Measuring speed is 0.1 second, lens diameter is accepted from 12 to 112mm, and the Abbe number is settable from 30 to 60 to suit the material being checked.

Touch Panel and Four Data Routes

A 7 inch LCD/TFT with capacitive touch panel provides the interface, a thermal printer is fitted, and data passes by Bluetooth, RS232, USB or WiFi.

Progressive Lens Dispensing

Progressive channel length is the one measurement that really distinguishes this particular instrument. A progressive lens performs according to how its corridor happens to sit in front of the eye, and measuring that channel alongside the power and the pupillary height lets a practice check that what was ordered really is what actually arrived, before a patient is asked to get used to wearing them at all.

Verification and Complaint Resolution

A 0.01 resolution step is what settles a tolerance dispute. When a patient returns saying a new pair is wrong, the question is whether the lens matches the prescription or it does not, and a hundredth of a dioptre will answer it definitively, where a quarter step leaves room for argument between the practice and the laboratory that made them up for the patient in the first place.

Contact Lens Practices

Soft and hard contact lenses are both measurable. For a practice checking a trial lens or verifying what a patient has arrived wearing, that removes the need for any separate equipment, and it means an unlabelled lens can be identified from its actual measured power, and not from what somebody wrote on a packet months earlier.

Optical Laboratories and Glazing Benches

A 12 to 112mm diameter acceptance covers both the small round lenses and the uncut blanks, and a 0.1 second reading matters a great deal when a whole tray is being checked. With four data routes including WiFi, the results reach a practice management system without being typed in by hand, which is where transcription errors most commonly enter into a record.

The Instrument Identifies the Lens

Automatic recognition removes a decision the operator would otherwise have to get right. Measuring a progressive lens in single vision mode gives an answer that looks plausible and is wrong, and that mistake is easiest to make when a bench happens to be busy. An instrument that recognises the lens type itself removes a whole category of error from the routine verification work of a whole bench.

Resolution Where Arguments Happen

Offering 0.01 alongside 0.12 and 0.25 means the instrument can work at the resolution the question requires. Routine checking does not need a hundredth of a dioptre, but a disputed pair of spectacles certainly does, and having that capability available on the same bench is what lets a practice resolve a complaint with evidence instead of an an opinion about how the lens simply happens to feel.

Everything the Dispensing Needs

Power, prism, PD, pupillary height and progressive channel length all come from one instrument in a tenth of a second. A dispensing decision depends on all of those together, so taking them on separate equipment, or estimating some of them, is how a well made lens still ends up in a frame that does not work for the person who is wearing it every single day.

The Visionstar D-910 reads sphere from 0 to plus or minus 25, cylinder and addition each from 0 to plus or minus 9.99, and prism from 0 to 15 cm/m, all selectable at 0.01, 0.12 or 0.25 steps, with axis across 0 to 180 degrees. Pupillary distance reads 40 to 90mm in 0.5mm steps, alongside pupillary height and progressive channel length. Single, progressive and automatic recognition modes are provided, ultraviolet and green light are measured simultaneously, and soft and hard contact lenses are both accepted. Lens diameter runs 12 to 112mm, measuring speed is 0.1 second, and the Abbe number is settable from 30 to 60 as needed. A 7 inch capacitive touch panel, thermal printer and four data routes are fitted, in a unit measuring 180 by 255 by 455mm.

Two points are worth noting. The card expresses lens powers in reciprocal metres rather than dioptres, which is the same quantity written differently, so no figure is in doubt. And no electrical supply specification, weight or accessory list appears on the material held. Nothing here should be read as a claim about testing or regulatory approval.

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

It describes how the corridor of a progressive lens is actually positioned, which is what determines how well the lens performs for the wearer. Measured alongside the power and the pupillary height, it lets a practice confirm that what arrived from the laboratory does match what the practice specified.

The sphere reads from 0 to plus or minus 25, cylinder and addition each from 0 to plus or minus 9.99, and prism from 0 to 15 cm/m. The axis covers 0 to 180 degrees in 1 degree steps, and pupillary distance reads from 40 to 90mm in 0.5mm steps right across the whole of its range.

Because it is what settles a tolerance question. Routine verification is done at 0.12 or 0.25, but when a patient returns unhappy with a new pair, a hundredth of a dioptre establishes whether that lens matches the prescription or not, which a quarter step would leave open to argument.

It means the instrument identifies the lens type itself, with no need for the operator to declare it. Measuring a progressive lens in single vision mode returns an answer that looks plausible and is wrong, so that recognition removes an error that is easiest to make whenever a bench happens to be busy.

Both soft and hard contact lenses are measurable upon it. That suits any practice checking a trial lens or verifying what a patient has actually arrived wearing, and it means an unlabelled lens can be identified from its measured power rather from whatever was once written upon its packet.

By Bluetooth, RS232 serial port, USB or WiFi, and a thermal printer is fitted as well. Four routes mean a reading reaches a practice management system without being typed in by hand, which is where transcription errors most commonly enter into any written record.

Lens diameter is accepted from 12 to 112mm, which covers both the small round lenses and uncut blanks on a glazing bench. Measuring speed is 0.1 second, so a whole tray of spectacles is checked through in a few minutes, where it might otherwise occupy a whole morning.

Because that is the unit the card uses. A reciprocal metre and a dioptre are the same quantity written two ways, so no figure on this page is in doubt, though a UK practice reading the original specification will be more accustomed to seeing the letter D set against those numbers.
