Couldn't load pickup availability
Fixed-PD optical trial frame for optometry refraction, the workhorse tool of every refraction lane, screening camp, and community eye clinic. Fixed 64mm interpupillary distance (adult male average). 360° rotating lens cells for precise cylinder-axis positioning during astigmatic refraction. Ultralight nylon construction, critical for patient comfort during long refractions (elderly patients and children fatigue with heavy metal frames). $249 direct, versus $450-$700 for Oculus UB4 / Topcon TT-01 / Reichert 12871 branded fixed-PD frames. Ideal for satellite clinics, screening camps, subjective-refraction training, and as a backup / dedicated pediatric or emergency frame.
Fixed-PD vs adjustable-PD: Which Do You Need?
Trial frames come in two flavors. Adjustable PD (Universal frames): PD dial spans 48-80mm, works for adults, children and variable IPD anatomy. Best as primary refraction lane frame. Fixed PD (this frame): locked at 64mm (adult male average). Simpler mechanism, lighter, faster to seat on patient. Ideal for screening camps (high throughput, mostly adult patients), backup / spare frame, subjective refraction training (student practices technique, PD not the variable), pediatric emergency (unbreakable, lighter). For a full refraction lane, buy both: this 64mm fixed and our Universal adjustable frame (SciMed 6940065726523, $249.99) as the pair.
Applications
- Screening camps and community outreach: high-throughput subjective refraction where PD adjustment slows workflow
- Optometry / ophthalmology teaching: student practice frame (PD adjustment is not the focus of learning)
- Backup / spare frame: every lane should have a second frame for busy days and when adjustable frame is out for repair
- Pediatric refraction (older children): lightweight, less intimidating than adjustable metal frames
- Rural and satellite eye clinics: cost-effective secondary frame
- Home visits and mobile refraction: lightweight travel frame
- Optical dispensary demo: patient trial-fit new prescription in demo frame before final glasses

FAQ
64mm PD works for what percentage of adults?
US/EU adult PD range typically 54-74mm. 64mm sits at the adult male mean and is ±3mm from ~85% of adult PDs. Small refraction inaccuracy from PD mismatch is clinically acceptable for screening / demo / teaching purposes. For final Rx dispensing, always use adjustable-PD frame or verify PD by pupillometer.
Fits any trial lens set?
Yes, universal 38mm cell diameter accommodates all standard trial lens sets (SciMed sets, Marco, Reichert, Topcon, Oculus and generic optometry sets).
How does this compare to Oculus / Topcon?
Oculus and Topcon trial frames are precision German/Japanese optical instruments with 1° axis calibration, tempered metal construction, +40 years reputation. This SciMed frame is a functional optical-quality frame for screening, teaching and backup. Price differential: $249 vs $450-$700. For a residency's primary refraction lane, invest in Oculus. For camp / teaching / satellite clinics, SciMed delivers 90% of the function at 40% of the cost.
