More features

• Material and Durability: This eye 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 optotype on the snellen chart is meticulously designed following the one-minute visual angle principle, guaranteeing precise measurements for accurate vision testing. The inclusion of red and green color bars facilitates the assessment of red-green color blindness.
• Convenient Testing Tools: It comes equipped with an eye patch and a pointer, allowing for individual testing of the left and right eye. 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 visual acuity chart. Typically, for adults, the "20/20" line should be at eye level, but for children, adjustments might be needed. The subject stands at a distance of 20 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.
