Material and Durability: This visual acuity chart is made of thick and durable PVC material, ensuring its sturdiness and waterproof capabilities. The matte finish eliminates glare and reflections, creating an optimal testing environment for accurate results.
Accurate Size and Design: The size of each letter is meticulously designed following the one-minute visual angle principle, guaranteeing precise measurements. The chart consists of the letter "E" in different orientations (up, down, left, and right). This means it can be used to test individuals who may not be familiar with or have difficulty reading letters of the alphabet from different languages. Besides, he red and green color bars facilitates the assessment of red-green color blindness.
Convenient Testing Tools: It helps measure visual acuity from a distance of 10 feet. The equivalent of 20 feet for testing is 10 feet (3 meters).Since the vision chart is rolled up for packaging, we recommend using our double-sided adhesive to affix it to the wall for easy usage.
Practical Mounting Recommendations: Avoid direct sunlight or overly dim spaces and ensure it is on a flat surface and kept vertical when posting the vision chart. Typically, for adults, the "10/10" line should be at eye level, but for children, adjustments might be needed. The subject stands at a distance of 10 feet from the chart during the test.
Versatile Applications: The eye chart is highly versatile and suitable for a wide range of settings. It plays an important role in educational institutions, eye clinics, hospitals, and other medical facilities where vision testing is essential.
