The Visionstar LY-220A is the 22-inch model in this LCD vision chart family, and its most revealing specification is one buyers usually skim past. At 6.5 kg gross it is the heaviest unit in the range — heavier than the 23-inch model above it, which ships at 5.6 kg — and it packs into a carton 180 mm deep against 120 to 130 mm for the smaller panels. A larger screen that weighs more than a bigger one, in a deeper box, indicates a different physical build rather than simply more glass.

The manufacturer does not state what accounts for the difference, and Medigear.uk will not speculate in detail. What can be said is that a heavier chassis behaves differently in a consulting room. A substantial panel mounted on a bracket resists the small displacements that accumulate in a working lane — a trolley catching a corner, a cleaner adjusting an angle, a patient steadying themselves on the wall. Those movements matter more than they sound, because a chart display whose position or angle has quietly shifted introduces an error into every measurement taken against it until somebody notices.

Working range runs from 1 metre to 6 metres, unchanged across this family. The lower end serves rooms that cannot host a conventional lane, and the upper end covers standard testing distance, so specifying this model is a decision about build and panel area rather than about reach.

The manufacturer describes the unit as detecting eyesight, myopia, hyperopia, colour blindness and astigmatism alongside other tests. Illustrations show letter acuity rows with values marked alongside, tumbling or Landolt optotypes, a red-green duochrome panel and a fixation cross, all driven from a handheld remote.

The supplied literature gives only screen size, packing dimensions and gross weight. Acuity range, brightness, resolution, power consumption, chart schedule and mounting specification are all absent, and every one should be settled in writing before an order. Medigear.uk supplies the LY-220A into UK optical practice with pre-despatch functional inspection, documentation review and full specification confirmation at quotation.

Permanently installed consulting room lanes are where this model belongs. A practice fitting out a room it expects to use for a decade wants the chart display fixed at a set height, a set angle and a known distance, and then left alone. Wall mounting achieves that, and a heavier chassis on a proper bracket holds it — resisting the incremental displacement that a busy lane inflicts on anything not properly secured.

The clinical consequence of drift is worth stating plainly, because it is easy to overlook. A chart display whose angle or position has shifted introduces an error into every acuity measurement taken against it, and there is no signal in the results that anything is wrong. The error simply persists until somebody thinks to check. A unit that stays where it was set removes that failure mode, which is a quiet but real contribution to measurement integrity across a practice's whole caseload.

Panel area suits general and low vision work alike. At 22 inches the display sits near the top of this family for chart area, which matters most at the largest optotypes and longest working distances — precisely the conditions of low vision assessment. Practices assessing acuities of 6/60 and below get more usable rendering than a smaller panel provides.

Short and awkward rooms remain fully served, since the 1 metre lower limit runs across this family. Specifying this model is a decision about build and area, not a trade against reach. Two points belong in the purchasing decision rather than the small print: the acuity range is unpublished and determines whether low vision work is possible at all, and the weight difference against the 23-inch model indicates a different physical build that the manufacturer has not explained — worth understanding before choosing between them.

Built to be fitted and left

The heaviest chassis in this range, on a proper bracket, resists the incremental knocks a working lane delivers. A display that has not moved is a display whose measurements you can rely on between checks.

Removes a silent source of error

A chart whose angle or position has drifted produces wrong acuities with no indication in the results. Eliminating movement eliminates the failure mode, which matters across every patient measured against it.

Panel area near the top of the family

At 22 inches the display renders the largest optotypes with more room than the smaller models, which is the condition that matters in low vision assessment at longer working distances.

Full short-distance reach retained

The 1 metre lower limit runs across this family, so choosing the more substantial model costs nothing in room flexibility. Difficult premises are served exactly as well.

Conventional distance covered too

A 6 metre upper limit means the same unit works in an ordinary arrangement, so it suits a standard consulting room as readily as a constrained one.

Self-illuminated, so lighting is not a constraint

The panel produces its own light and holds contrast under ordinary room lighting, unlike a projected chart. Rooms that cannot be reliably darkened are workable.

Nothing to replace on a schedule

No lamp, no fuse, no separate screen surface and no optical alignment. Maintenance is a screen wipe, remote batteries and a periodic check that the mounting is still tight.

Duochrome in the same sequence

A red-green panel supports spherical endpoint refinement without a separate chart, keeping a routine step inside the flow of the examination.

A deeper carton means better protection

The 180 mm packing depth, against 120 to 130 mm for the smaller models, gives the unit more protective volume in transit — a small thing that matters on a delivery to an upper-floor practice.

22-inch LCD display

A 22-inch LCD panel presents all charts with substantial area for the largest optotypes, producing its own illumination independent of room lighting.

6.5 kg gross weight

The heaviest unit in this range at 6.5 kg gross, indicating a more substantial physical build than the lighter models including the larger 23-inch panel.

Test distance 1 to 6 metres

The working range extends from 1 metre to 6 metres, covering very short rooms and the conventional testing distance from a single unit.

Acuity charts with marked values

Letter and optotype acuity rows are presented with acuity values shown alongside, as illustrated in the manufacturer's literature.

Myopia and hyperopia detection

The manufacturer specifies detection of visually associated myopia and hyperopia among the unit's stated capabilities.

Colour deficiency screening

Colour blindness detection is listed among the test types, supporting screening for colour vision deficiency from the same panel.

Astigmatism testing

Astigmatic targets are included among the stated test types for identification of astigmatic error.

Red-green duochrome panel

A red and green duochrome display supports spherical endpoint refinement using the eye's chromatic aberration, and red-green dissociation.

Fixation target

A fixation cross target is shown among the illustrated charts, supporting steady fixation assessment during the examination.

Handheld remote control

A remote drives chart selection from the clinician's working position, supplied with the unit.

585 × 180 × 500 mm packed

The packed carton measures 585 × 180 × 500 mm, notably deeper than the smaller models in the range and offering more protection in transit.

Part of a multi-size range

The model sits within a family spanning 18.5 to 23 inches including a variant described as 3D, so panel size and build can be specified to suit the installation.

The Visionstar LY-220A is the 22-inch model in this LCD vision chart family, and the specification that distinguishes it is its mass. At 6.5 kg gross it is the heaviest unit in the range — heavier than the 23-inch above it — in a carton half again as deep as its smaller siblings, which points to a more substantial physical build. For a permanently installed consulting room lane that matters, because a chart display that has quietly shifted produces wrong acuities with nothing in the results to show it, and a heavier unit on a proper bracket simply stays where it was set. Panel area sits near the top of the family, useful at the largest optotypes and longest working distances, while the 1 to 6 metre range is unchanged so nothing is given up in room flexibility. Acuity, myopia, hyperopia, colour deficiency, astigmatism and duochrome run from one remote on a self-illuminated panel needing no darkened room, no lamp and no alignment. Acuity range, brightness, resolution, power supply, chart schedule and mounting arrangement are all unpublished and should be obtained in writing before ordering, as should an explanation of the build difference against the 23-inch model. Medigear.uk supplies the LY-220A into the UK with pre-despatch functional inspection, documentation review and full specification confirmation.

FAQ

Frequently Asked Questions

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

The manufacturer does not explain it, and we will not guess at the engineering. What the figures show is a different physical build: 6.5 kg against 5.6 kg for the larger panel, in a carton 180 mm deep against 120 mm. Ask what accounts for the difference at enquiry — chassis material, stand type and bezel construction are the plausible candidates, and the answer bears on how you mount it.

Indirectly but genuinely. A display whose position or angle has shifted introduces a quiet error into every measurement taken against it, and nobody notices until something prompts a check. In a working lane, panels get caught by trolleys, adjusted by cleaners and leaned on by patients. A heavier unit on a proper bracket resists that, and a display that stays where it was set is a display you can trust between calibration checks.

For a permanent consulting room position, wall mounting is the better arrangement regardless of model — it fixes the height, fixes the angle and removes the desk footprint. The literature does not specify a mounting arrangement or confirm a bracket is supplied, and the illustrations show desk stands. Confirm what is included and whether a VESA fitting is present, and budget for a bracket if not.

One metre to six metres, the same across this family. The short end brings acuity measurement into rooms that could not otherwise host it; the long end covers conventional testing. Choosing this model costs nothing in reach.

The manufacturer lists eyesight, myopia, hyperopia, colour blindness and astigmatism detection, with illustrations showing acuity letter rows, tumbling or Landolt optotypes, a red-green duochrome panel and a fixation cross. A complete chart schedule is not published — request one in writing, particularly if binocular or contrast assessment is part of your routine.

Not published, and it is the most consequential omission. The acuity range determines whether the unit reaches far enough at the bottom for low vision work and high enough at the top for occupational standards. Obtain it in writing before ordering rather than after.

Colour blindness detection is listed among the capabilities, which indicates a screening function. Formal occupational colour vision assessment carries requirements around illuminant, plate condition and protocol that a general-purpose display may not meet, so confirm what plates are presented and to what standard if colour work matters.

The family runs 18.5, 21.5, 22 and 23 inches. At 22 inches this sits near the top for chart area, which matters most at the largest optotypes and longest working distances — relevant if low vision assessment forms part of the caseload. The practical difference between 22 and 23 inches is small; the difference in build, judging by the weights, is not.

Not published in the supplied literature. Confirm voltage range, plug configuration and consumption in writing at order, as OEM equipment of this class is produced for several regional markets and UK mains suitability should not be assumed.

No. An LCD panel produces its own light and holds contrast under ordinary room lighting, unlike a projected chart. Keep it clear of direct sunlight and strong reflected light, since surface reflection rather than absolute output is what degrades a monitor chart. Brightness is unpublished, so confirm it if the room is bright.

A vision chart display is a non-invasive ophthalmic device, most consistently classified as Class I under the UK Medical Devices Regulations 2002, or higher where configuration dictates. Manufacturer CE marking is noted where it appears in the product literature; Medigear.uk confirms CE marking, the declaration of conformity and current UKCA status against the shipping batch at quotation rather than asserting it in advance.

Clean the panel with a proprietary screen cleaner rather than an alcohol wipe, and replace remote batteries as required. Beyond that, the useful discipline on any permanently mounted chart is a periodic check that the mounting remains tight and the working distance is still what the software is set to — a fixture that has drifted is the one failure mode a maintenance-free display actually has. Typical warranty is 12 to 24 months against manufacturing defect, confirmed at quotation.
