Visual acuity test?
DefinitionThe visual acuity test is used to determine the smallest letters a person can read on a standardized chart or card held 14 - 20 feet away.Alternative NamesEye test - acuity; Vision test - acuityHow the test is performedThis test may be done in a health care provider's office, a school, a work place, or elsewhere. You will be asked to remove your glasses or contacts and stand or sit 20 feet from the eye chart. Keep both eyes open, you will gently cover one eye with the palm of your hand, a piece of paper, or a paper cup while you read out loud the smallest line of letters that you can see on the chart.If you are not sure of the letter, you may guess. This test is done on each eye, one at a time. If necessary, it is then repeated while you wear your glasses or contacts. You may also be asked to read letters or numbers from a card held 14 inches from your face. This will test your near vision.How to prepare for the testNo special preparation is necessary for this test.How the test will feelThere is no discomfort.Why the test is performedThe visual acuity test is a routine part of an eye examination or general physical examination, particularly if there is a change in vision or a problem with vision. In children, the test is performed to screen for any visual problems. Vision problems in young children can often be corrected or improved. Undetected or untreated problems may result in permanent damage to vision.Normal ValuesVisual acuity is expressed as a fraction. The top number refers to the distance you stand from the chart. This is usually 20 feet. The bottom number indicates the distance at which a person with normal eyesight could read the same line you correctly read. For example, 20/20 is considered normal. 20/40 indicates that the line you correctly read at 20 feet can be read by a person with normal vision from 40 feet away.What abnormal results meanAbnormal results may be a sign that you need glasses or contacts, or may mean that you have an eye condition that needs further evaluation by a doctor.Related topics:FarsightednessNearsightednessPresbyopiaWhat the risks areThere are no risks.

There are many different forms of RP, but the most typical forms effect the rod cells - those used for night and peripheral vision - first and as the disease progresses the cones - centeral acuity - are also lost restultung eventually in near total or total vision loss. There are some forms of RP that will progress differently and the rate of vision loss varies dramatically.
