Answer: C - Snellen
Explanation: A Snellen eye chart is used to measure visual acuity. This chart was developed in 1862 by a Dutch ophthalmologist Herman Snellen.
This chart uses alphanumeric capitals in its 5 by 5 unit grid. An example of the chart is attached.
The Snellen eye chart helps to determine the clarity of one's distance vision and it also helps to determine the legal visual acuity requirement for a valid driver’s license.
