MEDICO MANUAL DISTANCE VISION DRUM
Share
The Medico Distance Vision Drum is a rotating, cylindrical tool used to assess distance visual acuity in a clinical setting. This vision drum usually features multiple visual acuity charts, including Snellen charts, E-charts, or symbol charts for non-literate patients. Each chart is printed on a segment of the drum, and the practitioner can rotate the drum to present different charts or symbols to the patient at standardized distances.
Key Features:
- Rotatable Drum Design: Enables quick switching between various visual acuity charts for efficient examination.
- Multiple Chart Options: Offers different types of charts, such as Snellen letters, Landolt C, or tumbling E, allowing flexibility to assess different patient needs (for both literate and non-literate patients).
- Standardized Measurements: Charts are designed to conform to standard visual acuity measurements, often at distances such as 6 meters or 20 feet.
- Clear Visibility: The drum is often printed in high-contrast black and white, with anti-glare features for optimal visibility.
- Stable Stand: Comes with a secure stand or base for stability during testing, ensuring accurate results.
Uses:
- Distance Visual Acuity Testing: Measures the clarity of distance vision to detect refractive errors like myopia and hyperopia.
- Routine Eye Exams: Often used in eye clinics, hospitals, and optometry practices for quick and reliable vision screening.
The Medico Distance Vision Drum offers an efficient, non-digital way to conduct vision assessments, especially useful in settings without advanced electronic equipment.
