Oculus Trial Frames: Precision and Comfort for Subjective Refraction

If the ABDO Frame Rule is the tape measure of the optical world, the Oculus Trial Frame is the tailor-made suit. For over a century, OCULUS has set the gold standard for subjective refraction — delivering a realistic, real-world vision experience that a fixed phoropter simply cannot replicate.

Why Practitioners Choose Oculus

Unlike automated refraction systems, a trial frame allows the patient to maintain their natural head posture and sitting position throughout the examination. This matters enormously when assessing high-power prescriptions, multifocal needs, or patients with complex conditions such as nystagmus, where even small changes in head position can significantly affect the result. A trial frame puts the patient in the driver's seat — and puts the clinician in full control.

The Oculus range is hand-assembled from skin-friendly materials, built for long-term durability and extended patient comfort. Every element is independently adjustable — PD, temple tilt, nose bridge height — ensuring a precise, stable fit on any face. Most models accommodate up to 10 lenses (5 per side), giving the practitioner all the flexibility needed for even the most complex refractive combinations. A correctly fitted trial frame should have just three contact points: on the nose and behind each ear. This ensures stability and measurement accuracy throughout the exam.

Find the Right Model for Your Practice

The Oculus range covers every clinical scenario and patient group:

Oculus UB4 — The classic high-end model, featuring a CVD scale for vertex distance measurement and smooth "soft design" controls that are easy on the practitioner's hands during long clinic sessions. A reliable, versatile choice for everyday adult refraction.

Oculus UB6 — The next generation. Offering 12 lens slots (6 per side) and a refined 2.5° axis scale for outstanding reading accuracy, the UB6 is the go-to choice for practices handling complex prescriptions and demanding clinical scenarios.

Oculus UB3+ — At just 52 grams, this exceptionally lightweight frame is designed for simplicity and ease of use without compromising on adjustability. Ideal for practices where patient comfort and speed of set-up are a priority.

Oculus UB5 — Specifically scaled for smaller heads and children, the UB5 ensures accurate, reproducible results for your youngest patients — where getting the refraction right first time is especially important.
