Description
The Snellen Eye Chart (Alphabet-Type) is a standard tool for assessing distance vision. It helps users measure visual clarity and screen for nearsightedness, which causes blurry distance vision, especially in children. The chart is also used to determine if a person meets the legal visual acuity requirements for a driver’s license, typically 20/40 in most regions.
For accurate testing, it is recommended to have an assistant help during the evaluation. Users should wear their glasses or contact lenses if required for distance vision. The chart allows healthcare providers, educators, and individuals to monitor visual acuity effectively and detect vision issues early.
Directions for Use
-
Place the chart on a wall or easel 10 feet away from the test subject.
-
Cover one eye completely using a hand, large spoon, or other item (do not apply pressure).
-
Identify a line on the chart that can be read comfortably and read the letters aloud. Have an assistant record your accuracy.
-
Continue reading letters on successively smaller lines without squinting.
-
Stop when less than 50% of the letters on a line are correctly identified.
-
Switch to the other eye and repeat the test.
The Eye Chart Alphabet-Type is an easy-to-use and reliable vision screening tool, ideal for schools, clinics, and homes.
