Optical Trial Frame Adjustable PD 4880mm with Precision Lens Positioning for Vision Exams Description

Universal Optical Trial Frame For Optometry Product overview A fully adjustable trial frame designed for clinical optometry and vision testing. Built from titanium, aluminum, stainless steel, and precision plastic parts, this frame offers accurate positioning, multiple adjustments, and a compact kit for routine refraction and teaching use. Key benefits Accurate fitting and measurement: Adjustable interpupillary distance from 48 mm to 80 mm and an integrated eye distance ruler let you position lenses precisely and measure vertex distance for reliable lens conversion and subjective refraction. Flexible lens combinations: Holds up to five lenses simultaneously (three in front, two in back), reducing the need to swap lenses during tests and speeding up refraction workflows. Comfortable for extended use: Multiple adjustment knobs for pupil height, nose pads, and temple angle let you the fit for different wearers and maintain stable positioning during testing. Durable yet lightweight construction: Metal and engineered plastic construction balances durability with comfort. Net weight is about 50 g for comfortable wear; packaged weight listed as 1 kg. Clear viewing area: 31 mm field of view supports accurate visual assessment while maintaining patient comfort.
