Visionstar JD-2000B

Adjustable Tilting Display

The colour LCD tilts, which the manufacturer relates to a clear view from any position, whether the operator is sitting or standing at the instrument.

Touch Screen Operation

A sensitive touch LCD is fitted, so a measurement is completed by touching the screen, with recognisable icons presented across the measurement display.

Sphere, Cylinder and Add

Sphere reads 0 to plus or minus 25D, cylinder 0 to plus or minus 9.9D and add 0 to 9.99D, each selectable at 0.01, 0.12 or 0.25D resolution steps.

Automatic Lens Recognition

Single, progressive and automatic recognition modes are provided, so the instrument identifies a single or progressive lens without the operator declaring it.

Progressive Measurement Graph

A graph assists during progressive measurement, which the manufacturer relates to improved accuracy and speed across both near and far vision.

High Speed Ultraviolet Reading

The lens is held through the sensor and the display indicates the ultraviolet measurement on a progress bar, which the manufacturer describes as high speed.

Prism and Contact Lenses

Prism is presentable in X-Y or P-B form, cylinder as plus, plus and minus or minus, and both soft and hard contact lenses can be measured on the instrument.

Portable and Quick

Lens diameter is accepted from 20 to 108mm, pupillary distance reads 40 to 90mm in 0.5mm steps, measuring speed is 0.1s and the whole instrument weighs just 6kg.

Practices Without a Printing Requirement

This is the honest case for choosing the B variant. Where readings are entered into a practice management system anyway, or where a dispensing note is written up by hand anyway, a printer sitting at the instrument earns nothing. A practice in that position gets exactly the same measuring capability as the printing models, without paying for a function it was never going to switch on in the first place at all.

Rooms Where the Operator Moves

A tilting screen and a 6kg weight both suit an instrument that is read from different positions and carried between rooms. Where a dispensing table is used both seated with a patient and standing up alone, a fixed display forces the operator to stoop or to crane, and small daily awkwardness is what makes staff avoid a piece of equipment altogether, or else rush through the use of it.

Progressive Lens Verification

Automatic recognition and the progressive graph together address the lens type that causes most difficulty. Measuring a progressive in single vision mode gives a plausible wrong answer, and that error is easiest to make on a busy bench. An instrument that identifies the lens for itself removes a whole category of mistake from routine verification work of exactly that kind.

Coating and Tolerance Checks

High speed ultraviolet measurement lets a practice confirm what a lens actually transmits before any pair reaches the patient, and 0.01D resolution settles tolerance questions definitively. Together those cover the two things a practice most often has to demonstrate whenever a patient queries a pair that has come back from the laboratory.

You Pay for What You Use

A model that differs from its siblings only by leaving out a printer makes an unusually clean purchasing decision. The measuring capability is entirely identical, so a practice that records readings electronically or writes them up by hand buys exactly what it needs. That is worth saying plainly, because a specification sheet listing three similar models rarely makes the actual difference between any of them at all obvious.

A Display That Comes to You

A tilting colour screen sounds minor until an instrument is shared between people of different heights, or used seated with one patient and standing for the next. An operator reads that display dozens of times in a day, and whether it faces them or has to be peered at will decide how quickly they work and whether they bother reaching for the instrument at all during a busy working day.

The Instrument Knows the Lens

Automatic recognition removes a decision the operator would otherwise have to get right every time. A progressive lens measured in the wrong mode will return a figure that looks entirely reasonable and is not correct, which is the most dangerous kind of error, because nothing about it prompts a second look from whoever happens to be reading the screen at that particular moment.

The Visionstar JD-2000B reads sphere from 0 to plus or minus 25D, cylinder from 0 to plus or minus 9.9D and add from 0 to 9.99D, each selectable at 0.01, 0.12 or 0.25D steps, with axis across 0 to 180 degrees. Lens diameter is accepted from 20 to 108mm, pupillary distance reads 40 to 90mm in 0.5mm steps, and measuring speed is 0.1s. Single, progressive and automatic recognition modes are provided with a graph assisting progressive work, ultraviolet measurement is reported on a progress bar, cylinder and prism are each presentable in the usual forms, and both soft and hard contact lenses are measured. A 7 inch tilting touch screen is fitted and the instrument weighs 6kg.

Two points are handled deliberately. This model is listed on the card as having no printer, where the other two models on the same sheet have one, and that is the difference between them. Separately, the prism row is labelled as prism degree with a dioptre unit, where prism is conventionally expressed in prism dioptres, so that notation should be clarified. The electrical supply specification is not reproduced here.
