Description
This Frame-Mounted LogMAR Distance Vision Chart is a professional diagnostic instrument designed for permanent installation in ophthalmology clinics, optometry practices, and hospitals. Combining the clinical accuracy of the ETDRS logarithmic scale with a durable, sleek frame, this chart ensures a standardized and stable testing environment for high-precision visual acuity assessment.
Optimized for 3-meter (10-foot) testing, this wall-mounted version provides a clear, distortion-free surface that remains perfectly flat for consistent results across all patient screenings.
Key Features
-
Professional Frame Mounting:
-
Housed in a high-quality, durable frame that protects the chart from wear and tear.
-
Designed for easy wall mounting to ensure the chart remains at a fixed, standardized height and distance.
-
-
Gold-Standard LogMAR Design:
-
Features a standardized logarithmic progression, where each row represents a 0.1 LogMAR change.
-
Uses Sloan optotypes (C, D, H, K, N, O, R, S, V, Z) carefully selected for equal legibility to eliminate testing bias.
-
-
Uniform Testing Task:
-
Contains exactly 5 letters per row, standardizing the difficulty level at every visual acuity stage.
-
Maintains equal spacing between letters and rows to prevent “crowding” effects, which is critical for accurate diagnosis.
-
-
Multi-Notation Scoring (LogMAR, Decimal, Metric/Imperial):
-
Provides comprehensive scoring data on both sides of each row for rapid clinical recording.
-
Acuity range from 3/30 (LogMAR 1.0) for low vision down to 3/3 (LogMAR 0.0) for standard 20/20 vision.
-
-
High-Contrast & Anti-Glare:
-
Printed on premium, non-reflective matte material to eliminate glare from clinic lights, ensuring maximum contrast for the patient.
