Description
This Frame-Mounted LogMAR Tumbling E Chart is a specialized diagnostic solution designed for high-precision visual acuity testing in diverse patient populations. By utilizing the “Tumbling E” optotype within a rigid, professional frame, this chart provides a stable and reliable testing standard for both clinical and pediatric settings.
Calibrated for a 3-meter (10-foot) distance, this wall-mounted unit is perfect for permanent installation in exam rooms where accuracy and consistency are the top priorities.
Key Features
-
Universal Diagnostic Capability:
-
Features the “E” symbol in four orientations, allowing for easy testing of children, non-literate patients, or those with language barriers.
-
Patients can simply indicate the direction of the “E” bars using their hands.
-
-
Clinical-Grade Frame Mounting:
-
Housed in a durable, high-quality black frame that prevents warping or curling of the chart surface.
-
Ensures a perfectly flat testing plane for distortion-free viewing from all angles.
-
-
Logarithmic (LogMAR) Standardization:
-
Uses the ETDRS format with 5 “E Letters” per line and equal spacing between optotypes and rows.
-
Provides more granular and accurate data for tracking vision changes over time compared to traditional Snellen charts.
-
-
Comprehensive Acuity Ranges:
-
Offers a full spectrum of testing from 1.0 LogMAR (3/30) to 0.0 LogMAR (3/3).
-
Includes Decimal and Metric/Imperial notations for versatile clinical documentation.
-
-
Optimum Visual Clarity:
