Trial Lens Set
Free!
A trial lens set is a clinic-ready kit of loose lenses for precise subjective refraction. It includes spheres, cylinders, prisms, and useful accessories arranged in an easy-to-navigate case. Use it for routine exams, low-vision work, pediatrics, outreach, and training. Clear markings and durable rims speed testing and improve accuracy. Choose it to deliver reliable prescriptions with flexible, patient-friendly workflow.
Description
A trial lens set is a complete kit of loose lenses used for subjective refraction and binocular vision testing. It equips optometrists, ophthalmologists, and vision technicians to measure refractive error accurately with a trial frame. The set typically includes matched pairs of spherical and cylindrical lenses, plus prisms and common accessories. Clear markings and organized trays help clinicians work faster and keep results consistent across patients.
Key features and benefits:
• Comprehensive lens assortment for spherical, astigmatic, and prism testing.
• Clearly engraved powers with color coding that speeds selection.
• True-to-power manufacturing tolerances that support reliable prescriptions.
• Durable metal or high-grade polymer rims that resist wear from daily handling.
• Organized storage case that protects lenses and keeps workflow tidy.
• Optional accessories such as occluder, pinhole, cross-cylinder, and filters for balance tests.
Typical use cases:
• Routine eye exams and prescription updates.
• Low-vision refraction where natural head position matters.
• Pediatric and geriatric testing when a phoropter may be impractical.
• Mobile clinics, community screenings, and home visits.
• Training labs for teaching refraction techniques.
How it compares:
• Versus a phoropter, a trial lens set allows natural posture, flexible working distances, and easier use with specialty lenses or occlusion.
• Versus basic screening tools, it provides finer power steps and prism options for more precise results.
Buying considerations:
• Choose clear, legible markings and consistent color coding.
• Look for smooth, burr-free rims and accurate centering to avoid power errors.
• Prefer trays with logical layout to reduce handling time and misplacement.
• Keep lenses clean and scratch free to maintain optical quality.
• Select quantities and power ranges that match your case mix, from routine practice to low-vision and binocular vision work.
This set gives clinics a dependable, versatile platform for accurate, patient-friendly refraction.
