Why And How An Eye Test Is Performed The Eye test or visual screening measures your ability to see at various distances. Generally, an eye test or screening is performed with the help of an eye chart. During a routine eye exam, the first thing an opticianeye doctor does is test the vision of the patient using this chart. The chart has eleven lines of block letters and these letters decrease in size line by line. The best way to find out whether or not you need glasses or contacts to improve your vision, the aforementioned chart is used during the initial screening phase of a routine eye exam. The test is generally performed in the office of the optician. This includes a vision-screening test at the local DMV for a drivers license. Typically, you will be asked to stand or sit twenty feet away from the chart during a vision screening or eye test. In case the office of the optician isnt twenty feet long, the chart will be positioned behind you with a mirror placed on the opposite wall to replicate a distance of twenty feet. Once everything is in place, the optician will ask you to cover one eye and lead the letters on the chart aloud. The optician will ask you to begin at the top and work your way to the bottom. Once one eye has been tested, the same process will be repeated with the other eye and then with both eyes uncovered.
