What is eye vision scale?
The eye vision scale, also known as a visual acuity test, is a measure of how well a person can see at various distances. It is used to assess the sharpness and clarity of a person's vision. This test is often conducted by an eye doctor or optometrist using an eye chart with letters or symbols of different sizes. By evaluating the smallest letters or symbols that a person can identify correctly, the eye vision scale helps determine if corrective measures such as glasses or contact lenses are needed.
What are the types of eye vision scale?
There are several types of eye vision scales that are commonly used:
Snellen Chart: This is the most widely used eye vision scale that measures visual acuity at a distance. It consists of rows of letters or symbols that decrease in size.
Tumbling E Chart: The Tumbling E chart is commonly used for testing the vision of young children or people who cannot read letters. It consists of the letter 'E' rotated in different positions.
LogMAR Chart: This eye vision scale uses a logarithmic scale to measure visual acuity. It is often used for research purposes or in clinical trials.
Jaeger Chart: This eye vision scale is specifically designed for assessing near vision, commonly used for reading or other close-up tasks.
