Ophthalmic Visual Acuity Eye Test Chart – Tumbling E & Landolt C
The Ophthalmic Visual Acuity Eye Test Chart – Tumbling E & Landolt C is a practical clinical vision-testing aid designed for assessing a patient’s visual acuity at different levels. The product combines two commonly used non-alphabetic testing formats: the Tumbling E chart, which uses E-shaped symbols in different orientations, and the Landolt C chart, which uses rings with openings facing different directions.
The charts are particularly useful when conventional letter-based eye charts are unsuitable, including for patients who cannot read, young children, individuals unfamiliar with the Latin alphabet, or patients who need a symbol-based visual acuity assessment.
Tumbling E Visual Acuity Chart
The Tumbling E chart consists of progressively smaller E-shaped optotypes positioned in different directions. During examination, the patient identifies or indicates the direction in which the E is facing. This allows the examiner to assess the patient’s ability to distinguish progressively finer visual details without requiring the patient to recognize letters or words.
Landolt C Visual Acuity Chart
The Landolt C chart uses C-shaped ring optotypes with openings oriented in different directions. The patient identifies the position of the opening, providing a simple and standardized-style method of evaluating visual resolution. The progressively smaller rings allow assessment across different levels of visual acuity.
Features
- Dual-format visual acuity testing chart
- Tumbling E symbols for directional vision testing
- Landolt C rings for gap-direction testing
- High-contrast black symbols on a white background
- Progressively decreasing optotype sizes
- Clear and uncluttered chart layout
- Easy for patients to understand with examiner instructions
- Suitable for wall display in examination areas
- Lightweight and convenient for routine screening
- Useful alternative to conventional alphabet-based eye charts
Clinical & Professional Applications
This eye test chart can be used in:
- Ophthalmology departments
- Optometry clinics
- Eye hospitals
- Optical centers
- General medical clinics
- Primary healthcare facilities
- School vision screening
- Occupational health examinations
- Pre-employment vision screening
- Community eye-screening programs
- Pediatric vision assessment
- Routine visual acuity examinations
Advantages
The combination of Tumbling E and Landolt C formats provides healthcare professionals with flexible options for visual acuity assessment. Because both formats rely on symbol orientation rather than reading letters, they can be useful when testing patients with limited literacy, children, or patients who are not familiar with alphabetic characters.
The progressively smaller symbols provide a straightforward visual sequence for determining the smallest optotypes that a patient can correctly identify at the prescribed examination distance.

Ophthalmic Visual Acuity Eye Test Chart – Tumbling E & Landolt C is a professional vision-screening tool featuring two symbol-based visual acuity charts in one convenient set. The Tumbling E chart allows patients to identify the orientation of E-shaped symbols, while the Landolt C chart requires identification of the opening direction of C-shaped rings. With clear high-contrast symbols arranged from large to progressively smaller sizes, the charts provide a practical solution for routine visual acuity assessment in ophthalmology, optometry, medical clinics, schools, occupational health programs, and community screening activities.
