Visionstar SL-158

Product Code: EOAS-OAVT-3483

Red one side, black the other, so the right bank is obvious.

Reaching into the wrong group costs seconds on every lens change. The SL-158 rings its lenses in coloured plastic and groups them by colour across a 530 mm grey tray.

The Visionstar SL-158 is a trial lens set with plastic-ringed lenses, sharing a specification sheet with the metal-ringed JSL-158. The sheet gives two figures for the pair: a ring inner diameter of 36.5 mm and a size of 530 × 250 × 34 mm.

The photograph shows a grey tray with lenses in two ring colours, red and black, held in separate banks with labels above each group, and a central compartment containing a handled accessory. That colour split is the practical difference from its metal sibling, which shows a single ring finish throughout.

Grouping lenses by ring colour speeds up selection. A clinician reaching for a lens reads the colour before the label, so the correct bank is identified at a glance and lenses are returned to the right group rather than drifting between them. Exactly which lens types each colour denotes is not stated, and it should be confirmed, since sets differ in whether colour marks sign, type or power range.

Plastic rings are the other difference. They are lighter than metal and generally less costly to replace, which suits teaching clinics and any setting where sets are handled by many people. Against that, plastic is less resistant to knocks over years of heavy use, and a damaged ring is harder to reshape than a metal one. Where a set is used all day in one clinic, the metal-ringed JSL-158 may last longer.

Unpublished are the lens count, power range and steps, whether prisms and auxiliary lenses are included, the weight, the lens material, the ring outer diameter, and whether a case is supplied.

Teaching clinics are the clearest fit. A lighter, less costly set handled by many students suits training better than a premium one, and the colour grouping helps learners find and return lenses correctly.

Optometry and orthoptic courses equipping several benches can buy more sets for the same outlay, so more students work with their own tray.

Shared consulting rooms benefit from colour grouping, since several clinicians using one set are more likely to return lenses to the right bank.

Busy refraction rooms gain seconds on every lens change when the correct bank is identified by colour rather than by reading labels.

Practices replacing a damaged set may prefer plastic where cost matters more than working life.

Second sets for overflow rooms suit a lighter, cheaper option kept alongside a main set.

Heavy daily single-clinic use may favour the metal-ringed JSL-158, which resists knocks better over years.

Compatibility with existing frames depends on the unpublished ring outer diameter, which should be confirmed before purchase.

The Visionstar SL-158 is the plastic-ringed version of a full-size trial lens set, with lenses of 36.5 mm inner diameter grouped by ring colour across a 530 × 250 mm grey tray. The colour split is its practical advantage, since a clinician reads the colour before the label and lenses are returned to the right bank. Plastic rings make it lighter and generally cheaper to replace, which suits teaching clinics, shared rooms and second sets, while the metal-ringed JSL-158 suits heavy single-clinic use. What each colour denotes is not stated and matters at the chair, and the lens count, power range, weight, case and ring outer diameter are all unpublished. Medigear.uk confirms each in writing.

FAQ

Frequently Asked Questions

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

The photograph shows lenses in red rings and black rings grouped in separate banks. Trial sets commonly use ring colour to distinguish lens types, but the sheet does not say what each colour denotes here. Medigear.uk confirms before supply, since guessing would be worse than useless at the chair.

Ring material. The SL-158 uses plastic rings and the JSL-158 metal ones. They share the published inner diameter and tray size, and the SL-158 shows a grey tray with a two-colour lens layout.

They are a trade. Plastic is lighter and usually cheaper to replace, which suits teaching and shared use. Metal resists knocks better over years of daily handling. Neither is wrong; it depends on how hard the set will be used.

That depends on the ring outer diameter, which is not published. The 36.5 mm inner diameter is consistent with the common 38 mm format, but we confirm the outer diameter against your frames before supply.

Not stated. The model number may suggest a count, but the sheet does not give one. We confirm the full contents before you order.

Not published. We confirm the range, the steps, and whether prisms and auxiliary lenses are included.

It suits teaching well. A lighter, less costly set handled by many hands is a sensible choice for a training clinic, and the colour grouping helps learners find and return lenses correctly.

The sheet does not mention one, and the photograph shows only the tray. We confirm whether a case or cover is supplied, since an open tray collects dust.

Not published, though plastic rings will make it lighter than the metal version. We obtain the figure.

Not stated. The rings are plastic, but the lenses themselves may be glass or resin, which differ in weight and cleaning. We confirm the material.

Trial lenses are generally Class I medical devices under the UK Medical Devices Regulations 2002. Medigear.uk confirms CE marking, the declaration of conformity and UKCA status at quotation.

Clean lenses with an agent suited to their material, return each to its own colour bank, check rings for cracks, and cover the tray when not in use. Typical warranty is 12 months, confirmed at quotation.
