Illuminated Trial Lens Set — 225 Lenses, 20mm Reduced Aperture, Aluminum Mounts, Auto-Rise Tray
Couldn't load pickup availability
225-piece illuminated trial lens set — the complete refraction kit for optometry practices, ophthalmology satellite exam rooms, university teaching programs, and eye camps. Extra-white imported optical lenses with 20mm reduced aperture (edge-glare-free viewing), aluminum 38mm-diameter mounts (plus lenses one color, minus lenses another color — instant identification during subjective refraction), handled sphere lenses for easy manipulation, and auto-rising tray with integrated LED backlight controller. Attractive colored acrylic case with double lock. Includes trial frame + case + 1-year warranty. $549 direct — versus $1,500-$3,000 for TopCon / Nidek / Reichert trial lens sets.

Applications
- Subjective refraction — determining patient's optimal correction (sphere + cylinder + axis)
- Retinoscopy verification — confirming objective retinoscopy findings with subjective response
- Spectacle prescription — final Rx determination
- Contact lens over-refraction — verifying contact lens Rx
- Binocular vision assessment — Maddox rod, prism dissociation, phorias
- Low vision assessment — high-power sphere + telescopic magnifiers
- Pediatric refraction — screening + prescription in younger children
- Post-refractive surgery re-refraction — LASIK, PRK, corneal transplant follow-up
- Optometric teaching — student refraction practice + skills exams
Best for
- Optometry practices (primary exam-lane refraction workflow)
- Ophthalmology practices with subjective refraction bench
- Community eye clinics + rural practice outreach
- University optometry teaching programs (student lens sets)
- Cataract + vision camps + NGO outreach (Aravind, L V Prasad, Orbis)
- Emergency + urgent care (refraction workup)
- International eye clinics via DDP (India, LATAM, GCC, MENA, SE Asia)
- Veterinary ophthalmology (specialty refractive work)

FAQ
How does this compare to a Topcon TL-6000 or Nidek TL-2?
Feature parity on essentials — same lens power range, same 20mm aperture, same aluminum mounts, same Plano back vertex convention, universally compatible with any trial frame or phoropter. Topcon + Nidek have slightly higher lens polish + tighter tolerance QC. Price differential: $549 (complete kit) vs $1,500-$3,000+ (OEM lens-only, requires separate frame + illumination purchases).
What's included in the 225 lens count?
Sphere lenses (~90 pieces, +/- 20 D range in 0.25 D steps), cylinder lenses (~60 pieces, +/- 6 D), prisms (~15 pieces + rotary), auxiliary lenses (~10 pieces: pinhole, cross cylinder, red/green filters, occluders, Maddox rod), and various trial frame parts. Exact lens breakdown per standard 225-piece set convention.
Is the trial frame adjustable for children?
Yes — adjustable PD (interpupillary distance) 54-72mm, adjustable temple length, adjustable nose bridge. Fits adults + adolescents comfortably. For infants + very young children (age <5), pediatric-specific mini trial frame available separately (~$60).
Are individual replacement lenses available?
Yes — lenses drop/break during clinical use. Individual replacements $15-40/lens depending on power. Contact us with the specific lens power + type needed.
Does this work with an autorefractor?
Yes — after autorefractor gives objective refraction, transfer values to trial frame + let patient confirm/refine subjectively. Autorefractor + trial lens set is the standard 2-step refraction workflow.
