Description

• Material and Durability: Crafted from thick and robust PVC material, this visual acuity chart ensures durability and waterproof capabilities. Its matte finish eliminates glare and reflections, providing an optimal testing environment for accurate results.
• Accurate Size and Design: Each letter is meticulously sized according to the one-minute visual angle principle, ensuring precise measurements. The chart features the letter "E" in various orientations (up, down, left, and right), making it suitable for testing individuals unfamiliar with different alphabet letters or those who have difficulty reading. Additionally, red and green color bars aid in assessing red-green color blindness.
  
• Convenient Testing Tools: Aside from identifying the direction of the "E" on the chart, you can also assess for astigmatism by comparing line thicknesses on the astigmatism test chart. The chart is rolled up for packaging, and we recommend using double-sided adhesive for easy wall mounting.
• Practical Mounting Recommendations: Place the chart away from direct sunlight or dimly lit areas, ensuring it is flat and vertical when mounted. For adults, the "20/20" line should typically be at eye level, but adjustments may be necessary for children. During testing, the subject stands 20 feet away from the chart.
• Versatile Applications: This eye chart is highly versatile and suitable for various settings, including educational institutions, eye clinics, hospitals, and other medical facilities requiring vision testing.
