Eye Chart
What is Eye Chart?
An eye chart is a tool used by optometrists and ophthalmologists to measure visual acuity. It consists of rows of letters or symbols in varying sizes, with each row representing a different level of visual acuity. This chart is commonly used during eye examinations to assess an individual's ability to see clearly at different distances.
What are the types of Eye Chart?
There are several types of eye charts commonly used in eye examinations. The most well-known type is the Snellen chart, which features letters in decreasing sizes. Other types include the Tumbling E chart, which uses only the letter 'E' in different orientations, the Landolt C chart, which uses a ring with a gap that the patient must identify, and the Allen chart, which is used to test near vision.
How to complete Eye Chart
Completing an eye chart during an eye examination is a simple process. The optometrist or ophthalmologist will ask you to read the letters or symbols on the chart from a designated distance. They will start with the largest letters at the top and gradually decrease the size of the letters as you move down the chart. You should try to read the letters or symbols as accurately as possible without squinting or guessing.
