The Visionstar LY-22B is a wide-format LED-backlit vision chart. Where the standard illuminated chart is a narrow vertical column of acuity rows, this one measures 520 mm across against 380 mm — and that additional 140 mm is where its argument lives. The manufacturer's illustration shows the acuity rows occupying the main column with a further group of illuminated test panels alongside them, so a single wall unit presents more than one examination.

That matters in the settings illuminated charts actually serve. A screening room running acuity alone needs a narrow chart; a room that also checks colour vision, or looks at a duochrome comparison, or needs an astigmatic target, otherwise ends up with several separate items on the wall — each needing its own position, its own lighting and its own space. Consolidating them onto one internally lit face means the second and third checks are as immediately available as the first, which is precisely where a screening session tends to lose time.

The illumination principle is the same across this family and worth restating. Visual acuity depends on chart luminance, and a printed wall chart lit by the room varies with daylight, season and blinds. An internally lit face holds its own brightness, which makes results comparable between visits and between rooms. On a multi-panel chart that consistency extends to the additional tests as well — a colour or duochrome panel read under variable room light is considerably less reliable than one lit from behind.

Test distance is fixed at 5 metres, achieved directly or by mirror, and is not adjustable. The manufacturer states the chart is adjusted according to national standards without specifying which, and the exact complement of panels beyond the acuity rows is not itemised anywhere in the supplied literature. Both should be confirmed in writing.

The unit measures 1090 × 520 × 90 mm at 4.9 kg, packing four per carton at 21.4 kg gross. Frame construction is aluminium alloy with an LED light source. Medigear.uk supplies the LY-22B into UK optical practice with pre-despatch functional inspection, documentation review and full specification confirmation at quotation.

Screening rooms running more than one check are the natural setting. Occupational health assessment, pre-employment screening and school medicals frequently require acuity plus a colour vision check, and sometimes a duochrome or astigmatic look as well. Handled with separate items, each needs its own wall position, its own sight line and its own lighting — and in practice the second check is where a screening session slows down, because it means moving the patient or fetching something. One wide illuminated face presents everything together.

Colour vision screening benefits specifically from backlighting. Colour comparisons are sensitive to both the intensity and the colour temperature of the light falling on the printed surface, and daylight varies in both across a day and a season. A panel lit from behind removes that variable entirely, which makes a screening result taken in December comparable with one taken in June. A printed colour plate on a wall does not offer that.

School medical rooms and community screening services gain from the same consolidation, with the additional advantage that nothing can be misconfigured. Staff delivering high-volume screening are frequently not optometrists, and equipment with no settings to alter removes a whole class of error.

General optical practice uses wide illuminated charts as screening and corridor positions where a quick multi-element check is useful without occupying a full lane. Three things belong in the purchasing decision rather than the small print. The panel complement is not itemised in the supplied literature and is permanent once delivered. The chart standard is stated but not named, and must suit UK acuity notation. And the 5 metre distance is fixed, so the room must provide it before anything else is considered.

More than one examination on one wall

Acuity rows and further illuminated panels share a single face, so the second and third checks are as immediately available as the first — which is exactly where a screening session usually loses its momentum.

Consistent light across every panel

Backlighting holds brightness and colour temperature steady for all the tests on the face, not just the letters. That matters most for colour and duochrome comparisons, which are sensitive to both and which daylight changes constantly.

Colour screening that survives the seasons

A printed colour plate read under December light is not the same test as one read in June. An internally lit panel removes the variable, making results comparable between visits and between rooms.

One wall position instead of several

Separate items each need their own space, sight line and lighting. Consolidating onto one 520 mm face frees wall area and removes the positioning compromises that come with hanging three things where two will fit.

Nothing to configure or misconfigure

No settings, no software, no distance to enter. In screening rooms staffed by non-specialists that removes an entire category of error, because there is nothing one user can leave wrong for the next.

Essentially no failure modes

No display panel, no firmware, no lamp on a replacement schedule and no battery. An LED array behind a printed face is about as robust as clinical equipment gets.

Light and shallow despite the width

At 4.9 kg and 90 mm deep the unit fixes to any sound wall without structural consideration, projecting barely further than a framed picture despite carrying half a metre of chart face.

Genuinely inexpensive to own

No consumables, no lamp, no licence, no calibration subscription and no service contract. After purchase the running cost is the electricity.

Wide-format illuminated face

The chart measures 520 mm across against 380 mm for the standard column format, providing space for additional test panels alongside the acuity rows.

LED backlit illumination

An LED array behind the face provides even internal illumination across the whole chart, holding consistent luminance independent of ambient room lighting.

Acuity rows in the main column

Visual acuity optotypes occupy the principal column of the face, presented at the fixed 5 metre working distance.

Additional illuminated test panels

The manufacturer's illustration shows further panels alongside the acuity column; the complete complement is not itemised in the supplied literature and should be confirmed in writing at enquiry.

Aluminium alloy frame

The chart is housed in an aluminium alloy frame, resisting handling damage and providing a rigid, stable mounting.

Fixed 5 metre test distance

The chart is designed for a 5 metre working distance, achieved directly or by mirror; the distance is not adjustable.

Adjusted to national standards

The manufacturer states the chart is adjusted according to national standards; which standards apply should be confirmed as appropriate for UK acuity notation.

1090 × 520 × 90 mm

The unit measures 1090 mm high, 520 mm wide and 90 mm deep — the same shallow projection as the narrow format despite the wider face.

4.9 kg unit weight

At 4.9 kg the chart mounts to any sound wall without structural assessment or specialist fixing.

Four units per carton

Charts pack four to a carton at 21.4 kg gross in a 1110 × 380 × 540 mm box, suiting multi-room and multi-site orders.

No consumables or settings

There is no lamp to replace on a schedule, no paper, no batteries, no software licence and no user-adjustable setting that could be left wrong.

The Visionstar LY-22B is a wide-format LED-backlit vision chart, and the extra 140 mm across the face is the whole point of it. Acuity rows share the illuminated surface with further test panels, so a screening room checking more than letters presents everything on one wall, lit identically and immediately available — rather than spreading separate items around the room, each needing its own position and its own light. That consistency matters most for colour and duochrome work, which is sensitive to both the intensity and the colour temperature of ambient light and which a backlit panel makes reliable across seasons. At 1090 × 520 × 90 mm and 4.9 kg it fixes to any sound wall, packs four to a carton, has no settings to misconfigure and essentially no failure modes. It suits occupational health and pre-employment screening, school medical rooms, community screening services and multi-element corridor positions in general practice. Three things must be settled first: the 5 metre distance is fixed and the room must provide it, the panel complement is not itemised and is permanent once delivered, and the chart standard should be confirmed as appropriate for UK acuity notation. Medigear.uk supplies the LY-22B 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's illustration shows acuity rows in the main column with a further group of illuminated panels alongside — what appear to be a red-green comparison square, a circular radiating target and a dotted plate. The literature does not itemise them, so we will not state what each one tests. Request a written schedule of every panel before ordering, since on a fixed printed face that complement is permanent.

Because you cannot change it later. A digital chart display can add tests through software; a printed illuminated face cannot. Whatever panels the chart carries on delivery are the panels it will carry for its whole working life, so the schedule is not a detail to settle afterwards.

Consolidation. A room needing acuity plus a colour check plus a duochrome comparison otherwise ends up with several separate items on the wall, each needing its own space, position and lighting. One wide illuminated face presents them together, lit identically, immediately available.

More than it does for the letters, arguably. A colour or duochrome panel read under variable room light is considerably less reliable than one lit from behind — daylight changes both the intensity and the colour temperature falling on a printed surface, and colour comparisons are sensitive to both. Backlighting removes that variable.

No. This model is fixed at 5 metres and the room must provide that directly or by mirror. There is no adjustment and no scaling; if your room cannot deliver 5 metres, an LCD chart with adjustable distance is the appropriate product instead.

The manufacturer states it without naming the standards. Acuity notation and chart geometry differ between markets, and a UK practice needs a face appropriate to British notation. Ask which standard the printed face is drawn to, and confirm the acuity range, before ordering.

The literature does not specify mounting or confirm that fixings are supplied. At 4.9 kg and 90 mm deep it is a light wall fixing well within any sound wall, but the 520 mm width needs more clear wall than the narrow format — check the intended position accommodates it, particularly beside door frames or in corridors.

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.

The literature does not say. On some illuminated designs the printed face is replaceable and on others integral. Given that the face determines the instrument's entire clinical scope permanently, ask whether alternative faces exist and at what cost — it bears on how long the unit stays useful if requirements change.

It has none of the flexibility — no randomised sequencing, no alternative optotype sets, no adjustable distance, no software. In exchange it has almost nothing that can fail, needs no configuration, cannot be misconfigured by one user and left wrong for the next, and costs considerably less. For a screening position running a fixed set of checks repeatedly, that is frequently the better trade.

An illuminated acuity chart 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.

Wiping the face, and eventually whatever the LED module requires. No lamp on a schedule, no screen alignment, no software, no batteries. The useful discipline is a periodic check that the mounting remains secure and the 5 metre distance is still what the room provides. Typical warranty is 12 to 24 months against manufacturing defect, confirmed at quotation.
