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.

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 day-to-day work of refractionists, and put them into practice with a clear objective in mind. The result is plain to see. It makes everyday work easier for every refraction professional – and that’s what it’s all about.
Fashioned by hand – scrutinized by high-tech coordinate measuring machines
