Description
This LogMAR Tumbling E Distance Vision Chart is the gold-standard diagnostic tool for assessing visual acuity in patients who are pre-literate, non-English speaking, or non-verbal. By using the standardized “E” optotype in four different orientations (up, down, left, right), this chart eliminates the need for letter recognition while maintaining clinical precision.
Designed for 3-meter (10-foot) testing distances, this foldable, frame-mounted chart is specifically engineered for portability and accuracy in diverse clinical and field environments.
Key Features
-
Universal “Tumbling E” Design:
-
Ideal for testing young children, illiterate adults, or patients with language barriers.
-
Patients simply point or gesture the direction of the “E” limbs (up, down, left, right).
-
-
Logarithmic (LogMAR) Precision:
-
Features equal spacing between characters and rows, standardizing the task across all visual levels.
-
Provides a more sensitive and repeatable measurement than traditional Snellen charts.
-
-
3-Meter Optimized Testing: * Specifically calibrated for a 3-meter (10-foot) viewing distance, making it perfect for smaller exam rooms and mobile screenings.
-
Portable & Foldable Frame: * The frame-mounted design includes a hinge for easy folding, allowing it to fit into most travel bags for mobile clinics or home visits.
-
Multi-Notation Scoring:
-
Includes notations for LogMAR (1.0 to 0.0), Decimal (0.10 to 1.00), and Metric/Imperial equivalents (3/30 to 3/3 or 10/100 to 10/10).
-
-
Durable & Professional Build:
-
High-contrast printing on a non-reflective, matte-finish material to prevent glare and ensure longevity.
