What do these fractions mean? When we say that an eye has 6/24 visual acuity, we mean to say that the smallest row of letters the tested eye can discern at a distance of 6 metres is what a normal eye can discern at a greater distance of 24 metres. From this, we can see that the numerator 6 is a constant. The denominator varies and a number greater than 6 would represent less than normal visual acuity. The larger the denominator number, the poorer is the vision. 6/6 visual acuity is normal vision. 6/5 represents the fortunate 10 percent of the population that has better than normal vision. The legal visual requirement to obtain a driving license is 6/12 in most countries. A person seeing worse than 6/60 despite best spectacle correction is considered to be legally blind. About 10 percent of people are fortunate to have better than 6/6 vision, that is 6/5. The test is ideally done at 6 metres because light rays from objects seen at 6 metres and beyond reaches the eye as parallel rays and in the NORMAL EYE are focused precisely onto the central macula region of the retina without the need for any focusing effort. In some countries, normal visual acuity is designated as 20/20 which simply is the same measurement designated in feet. In other countries, the fraction is converted to a decimal figure but they mean the same thing. Instructions Stand at a distance of 3 metres or 10 feet from the monitor and read down to the smallest row of numbers that you can see.Test one eye at a time, first without your glasses and then with. Keep your other eye covered using an eye patch. To make a simple eye patch, just fold a piece of tissue and tape it over your eye.Your visual acuity is given by the fraction (i.e. 6/60, 6/36, 6/24, 6/18, 6/12, 6/9, 6/6 or 6/5) designated to the smallest row of numbers you can read correctly.First test your right eye, then your left eye. Record your visual acuity without (unaided visual acuity) and with your glasses (aided visual acuity) Start Test Interpreting The Results Normal good visual acuity is 6/6. If your visual acuity is worse than 6/6, move on to the next test, the Pin Hole Test. The Pin Hole Test will determine whether you need to wear corrective glasses to see better.

风景很美由小养成良好的用眼卫生习惯。 我怎么能去学校问人家医生呢,而且不知道医生什么时候去学校例行检查,孩子只顾着玩哪像大人一样的细心,一检完就飞也似的跑开玩了。点击展开...原来是学校的检查,我还以为是自己去眼科医生那里检查的
