Description

A method for measuring an eyesight using computer and an electronic writing medium structured}

The present invention relates to a method for measuring vision using a computer and an electronic recording medium having the same, which will be described in more detail, displaying a circular shaped vision measurement symbol having a part open on a monitor screen of a computer, and measuring vision. When the user identifies the open part of the circular visual acuity symbol, which is displayed on the monitor of the computer, and makes an identification response using the input device of the computer, the accuracy of the identification response is determined. If the identification response is incorrect, the corresponding visual acuity measurement result is displayed, and if the identification response is correct, a visual acuity measurement method using a computer that sequentially displays a visual acuity symbol smaller than a previously displayed visual acuity symbol, and It relates to the established electronic recording medium.

In today's society, computers are indispensable for information retrieval, hobbies, e-commerce, and business performance, and the use of computers is increasing rapidly. Is widely used and used. As the use of computers expands, they provide great benefits for each individual's life and performance.However, the use of a computer requires an image output device such as a monitor. As you work on a computer, fatigue builds up in your eyes, which causes frequent vision deterioration. As such, when eyesight is deteriorated, conventionally, for eyesight measurement, there is a method of measuring eyesight by using an expensive eyesight measuring equipment and a professional eyesighter by visiting a hospital or an optician or measuring eyesight using an eyesight measurement table. . Although there is an advantage that accurate vision measurement can be performed when using the expensive vision measuring equipment, it takes a considerable time because you have to visit the hospital or optician equipped with the vision measuring equipment and also use the vision measuring equipment. Therefore, there is a disadvantage in that the cost burden accordingly.

In addition, the method of measuring the eyesight using the eye chart has the disadvantage that the individual needs to have a separate eye monitor because the individual cannot measure the eyesight alone, and there is a considerable distance from the eyesight table (for example, 3 To 5 meters) is an inconvenience to measure.

In addition, the conventional method for measuring eyesight using a personal computer simply reduces the visual acuity table and displays it on a computer monitor. Therefore, it is difficult to trust the measured value for actual measurement, and small letters are distinguished when considering the resolution of the monitor. Because of this difficulty, it is difficult to use for actual visual acuity measurement. For this reason, a method of measuring visual acuity using fonts or letters has a disadvantage in that reliability of the measurement result is low.

Conventionally, a visual acuity measuring method using an image media device has been developed. However, the visual acuity measuring method needs to be measured at a considerable distance away from the visual acuity device. There is still a problem that vision measurement is difficult.

The present invention is to solve the above problems, a portion of the circular shape of the eye measurement symbol is to be displayed on the monitor screen of the computer to measure the eyesight can easily measure the eyesight using a computer The present invention provides a method for measuring vision using a computer and an electronic recording medium having the same.
