The refraction classic gets a new design

Subjective refraction is even simpler and more comfortable with the OCULUS Universal Trial Frame UB 3+ – a real step forward for refractionists and clients alike. Not only is the UB 3+ exceptionally lightweight; all of its operating elements have been ergonomically shaped, and every detail designed with functionality in mind.

The new Universal Trial Frame has a chic and modern appearance, further emphasizing the skill of the refractionist. One thing will never change though, and that’s OCULUS’ signature quality. The OCULUS UB 3+ is also 100 % made in Germany. All 218 individual components are assembled by hand so that every tiny detail is perfect.

Functions

What makes OCULUS UB 3+ special?

  • Functional and modern design
  • Optimized grooving on all operating elements makes them easy to handle and clean
  • Nose rack with anatomically shaped nose pad for optimal pressure distribution
  • Matt surface with laser-etched aluminum scales – highly scratch resistant and readable
  • Optimized mix of materials: exceptionally gentle on skin and very lightweight (just 52 grams)
  • Spring rear lens holder for safety
  • OCULUS quality – all individual components are assembled by hand, and made in Germany

The secret to the success of the Universal Trial Frame UB 3+

We listened very closely to our clients when we developed the new UB 3+. We gathered and examined lots of feedback and suggestions from the every day work of refractionists and put them into practice with a clear objective in mind. The result is plain to see. It makes every day work easier for every refraction professional – and that’s what it’s all about.

Reversible polarizer

The optional Hegener reversible polarizer is mounted directly onto the Universal Trial Frame.

OCULUS Universal Trial Frame UB 3+: Refraction in perfection – proven and new

FAQ

Universal Trial Frames UB 3/UB 3+, UB 4 and UB 6 are all suitable for any trial lens conforming to DIN EN ISO 9801 and having a rim diameter of 38 mm, such as a OCULUS “tl” trial lens.
However, our Universal Trial Frame UB 5 for small heads requires trial lenses of the “tls” line with a diameter of 28 mm. These also conform to DIN EN ISO 9801 and are available nowhere in the world but from OCULUS.

The UB 5 was developed for small heads, which means that it will fit many adults as well, especially among the elderly. It has a PD range of 40-72 mm. In order to achieve such low PD values without changing the lens diameter (21 mm) it was necessary to reduce the rim diameter. That’s the simple idea behind the OCULUS UB 5: It’s ideally suited for small heads including those of children.

The UB 6 stands out for its trendy, modern design. The nose pad has been improved for better pressure distribution as well as in terms of adjustability. In addition, the front lens holder now offers four instead of the usual 3 slots, while the rear lens holder accommodates two lenses, as before.
Unique to the design of the UB 6 is the gradation of the scale for reading off the axis and base position, which is now in steps of 2.5°, allowing for greater reading accuracy. The operating elements now have an attractive conical design and are grooved to provide a better grip. Their somewhat harder material makes them more durable than those of earlier models.
The aluminium scales are absolutely abrasion-proof. Their high contrast makes for easy reading also in darkened rooms. The upward angled operating element for precise nose pad adjustment has been designed for easy use outside the test person’s field of view.
The flexible arms adapt to the shape of the ears and do not need to be adjusted.
All modifications and improvements were made in response to customer requests.

Yes, all spare parts are available. Please contact the distributor from whom you bought your trial frame.

Yes, all components of every one of our Universal Trial Frames are assembled manually with great precision. Here too, we stay true to our quality claim: Made in Germany – made by OCULUS.

Yes, polarizing filters are always optionally available. Those for the UB 6 have a clip for easy mounting, while those for the UB 4 and UB 5 are to be directly slipped onto the trial frame.
Polarizing filters with a clip as well as those of the slip-on type are for lateral mounting and can be easily flipped to the side when not needed.
On the UB 3/UB 3+ the polarizing filter has a central mount and can be simply removed after use. All linear polarizing filters are reversible.
Circular polarizing filters are available both with a clip and in a slip-on version.
There are also circular polarizing filters available in trial lens size for use in a slot of the rear lens holder if one should be free.

To mount the polarizing filter, insert the pin of the filter into the transverse borehole in the trial frame and push the pin in until it locks into the place the first time. This is the top position, and it is used for testing distance vision. To test near vision, push the polarizing filter all the way down until it locks into place in the bottom position. This procedure is also described in the instructions for use delivered with the polarizing filters.

If necessary we recommend cleaning your trial frames with a soft lint-free cloth only. To clean a heavily soiled trial frame you can use a damp cloth and a little household dishing-washing liquid. Never use alcohol, ether or similar solvents, let alone aggressive chlorinated, scouring or corrosive detergents.
For disinfection we recommend disinfection cloths such as Pursept®-A Xpress or Mikrozid® Sensitive Wipes from Schülke und Mayr GmbH. Please contact your OCULUS distributor so that they can order through OCULUS, or contact the source supplier directly: www.schuelke.com.

The UB 5. Use the operating element (knob) to set the nose pad to the desired height, then pull the knob out slightly. This locks the nose pad at the set height.

Yes, it conforms to DIN EN ISO 8429.

The warranty period is one year from delivery, or from acceptance, if acceptance is required.

The UB 4 has a small Phillips screw for adjusting the resistance. The UB 6 has instead a small hexagon socket screw for this purpose (hexagon screwdriver included in delivery).

Universal Trial Frames UB 3+, UB 4, UB 5 and UB 6 are all delivered in a telescopic cardboard box.
This telescopic box has been designed so that it can be used for storing the trial frame in a drawer or together with the refraction unit. It is lined with hard-wearing PE foam to protect the trial frame.

Yes. None of the OCULUS Universal Trial Frames contains latex.

UB 3/UB 3+, UB 4 and UB 5: Three slots in the front lens holder and two in the rear lens holder on either side ⇒ 10 slots altogether

UB 6: Four slots in the front and two in the rear lens holder on either side ⇒ 12 slots altogether.

No, the end-pieces differ in design, so they cannot be switched between the UB 4 and UB 6.

No, the nose racks differ in design, so they cannot be switched between the UB 6 and UB 4.

No, the nose racks differ in design, so they cannot be switched between the UB 4 and UB 6.

No, each polarizing filter is fine-tuned to the design of the trial frame it is intended for, so it cannot be switched between the UB 6 and UB 4.

No, each polarizing filter is fine-tuned to the design of the trial frame it is intended for, so it cannot be switched between the UB 4 and UB 6.

Yes, the nose pads of these two models are interchangeable.

No, each lens holder is designed to precisely match the trial frame it is intended for, so the lens holders cannot be switched between the UB 4 and UB 6.

Yes, provided that the UB 4 has round operating elements only. They do not fit on older UB 4 models that have conical operating elements for adjusting pupillary distance.

UB 6: four nose pads in total
UB 5: three nose pads in total
UB 4: three nose pads in total
UB 3+: two nose pads in total

Yes, with the exception of the UB 3.

UB 6: approx. 61 g
UB 5: approx. 48 g
UB 4: approx. 64 g
UB 3: approx. 58 g
UB 3+: approx. 52 g (10 % lighter than the UB 3)
note: specifications are subject to change!

The transparent sighting bar has one scale on its surface and one inside. Take your VD reading when you see the two scales in alignment. The millimetre values on the scale refer to the eye-side vertex of a trial lens located in the first slot of the rear lens holder (next to the trial frame body).

DIN EN ISO 1366 defines VD as follows: absolute value of the distance between the rear surface of the spectacle lens and the corneal apex measured along the line of sight, i.e. orthogonally to the plane of the rim.
The measurement should be taken with the reference lens in the first slot of the rear lens holder (next to the trial frame body).
