LogMAR Low Contrast Chart- OT, Frame Mounted

This LogMAR 10% Contrast Sensitivity Chart is a specialized diagnostic instrument designed to measure a patient’s visual function under low-contrast conditions. By testing the ability to distinguish objects from their background, this chart helps detect early-stage vision loss that standard high-contrast charts might miss, such as early cataracts or glaucoma.

Available in both Alphabet and Tumbling E versions, these charts are frame-mounted for maximum stability and a professional clinical appearance.


Key Features

  • Precise 10% Contrast Level:

    • Features optotypes printed at a standardized 10% contrast to evaluate functional “real-world” vision.

    • Critical for assessing tasks like driving in fog or navigating low-light environments.

  • Two Specialized Optotype Versions:

    • Alphabet: Uses standardized Sloan letters for literate adult patients.

    • Tumbling E: Ideal for pediatric use, non-literate patients, or those with language barriers.

  • Logarithmic (LogMAR) Accuracy:

    • Follows the ETDRS-style layout with 5 symbols per line and equal spacing between rows.

    • Standardizes the difficulty level across all visual acuity stages for repeatable results.

  • Durable Frame-Mounted Design:

    • Housed in a rigid black frame to ensure the chart remains perfectly flat and distortion-free.

    • Provides a sleek, medical-grade aesthetic suitable for professional eye clinics.

  • 3-Meter (10-Foot) Calibration:

    • Specifically calibrated for a 3-meter testing distance, making it versatile for most exam rooms.
