Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing an eye injury caused by a long-term operation of a personal computer.

[0002]

2. Description of the Related Art When gazing at an OA device such as a personal computer for a long time, radiation generated from a monitor causes radioactivity to accumulate in the user's body, or injury to a wrist or shoulder due to operation of a mouse and keyboard. May be given.

[0003] However, since a large number of nerves are concentrated on their wrists and shoulders, fatigue is easily felt. However, if a certain period of rest is taken, the fatigue is almost recovered. However, some are less tired and the user is more susceptible to injury, which is an eye injury that is commonly used frequently.

When operating a personal computer and watching the monitor, both eyes concentrate on the information on the screen. In particular, the faster the PC responds, the more the user's attention concentrates on the monitor, and the brightness of the screen, the distance between the eyes and the screen, the focus and the point to watch are constant over a long period of time. , The visual function may be rapidly deteriorated.

[0005]

According to the physiological structure of the eye, when the monitor is gazed at for a long time, all physiological structures (muscles, etc.) of the eye are almost stopped, and the state in which the hand is raised is reduced. It is the same as holding. In that case,
Since the muscle is in a stopped state, it cannot supply nutrients and cannot discharge waste generated by metabolism. In addition, the muscles around the eyes have very few nerves, so they are less likely to feel tired than the hands.

[0006] Therefore, even if there is an injury to the eye muscles, subjective symptoms are unlikely to appear, and only symptoms such as reduced visual acuity, headache, eye fatigue, dryness, and near vision appear. Further, a device for treating various symptoms caused by inflammation of the eye muscles is disclosed in US Pat.
Although disclosed in US Pat. No. 800, the device, like other myopia treatment devices on the market, is intended to be used after the eye has been injured, and is not to be prevented in advance.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a method for preventing eye injuries caused by a long-term operation of a personal computer. During this time, the muscles around the eyes are fully exercised and the eyes are alleviated.

[0008]

In order to achieve the above object, the present invention provides (1) a step of accumulating the operation time of a personal computer, and (2) a predetermined first interval in which the accumulated time is set in advance. When a time (T1) is reached, a screen showing a blinking instruction to the user appears on the monitor; (3)
A predetermined second interval time (T
When reaching 2), a step in which a screen for instructing the user to rest the eyes appears on the monitor; and (4) when "Yes" is selected in the screen for instructing the rest of the eyes, various steps to alleviate eye fatigue When "No" is selected in the step in which the screen is displayed and the screen instructing the (5) rest, the set value of the second interval time (T2) is reduced, and the process returns to the step (1). And a method for preventing eye injury due to long-term operation of the personal computer, comprising the steps of:

[0009]

FIG. 6 shows the screen immediately before disappearing completely when the screen of FIG. 6 enters the natural background screen and the screen of FIG. 6 disappears from the screen when the exercise to be relaxed is selected. FIG. 10 is a diagram showing a case where a picture that allows a user to check whether his / her eyesight has deteriorated is provided on a wall near the extension line, FIG. 10 is a screen during operation of a personal computer according to the present invention, and FIG. It is a figure in the case of changing the brightness of FIG. 10 in invention.

As shown in FIG. 1, according to the present invention, (1) when the operation of the personal computer is started, the operation time is automatically accumulated (block 11), and this is calculated (block 12). Time (T1) and the second interval time (T
And (2) when the accumulated time reaches the set value of the first interval time (T1) (block 13), a previously input screen appears on the monitor and instructs the user to blink. (3) when the accumulated time reaches the set value of the second interval time (T2) (block 15), a message appears as to whether or not to enter the eye exercise program (block 16); 4) "Y
If "es" is selected, a screen for alleviating various types of eye fatigue appears (block 17), and (5) "N"
When "o" is selected, the setting value of the second interval time (T2) is gradually reduced (block 19), and the process returns to the step (1).

The blinking time (T3), the exercise time (T4) for alleviating eye fatigue and the image are all input in advance (block 12), and the exercise time (T4) for alleviating eye fatigue is completed. Alternatively, if the user inputs a stop command (block 18), the process returns to the step (1) (block 11) and starts accumulating time again.

If the user does not select an exercise program for alleviating eye fatigue at the second interval time (T2), "exercise the eyes" at an interval shorter than the first second interval time (T2). "Message appears repeatedly. That is, in the step (5), the second interval time (T2) is reduced by, for example, an arithmetic series or other decreasing series based on the number of times of selection of "No". Further, once the process proceeds to step (4), the process immediately returns to the first set time as the second interval time (T2) instead of returning to the shortened set time.

The screen used for the exercise for alleviating eye fatigue in the step (4) includes a screen for performing up / down / left / right exercise, brightness change, focus adjustment, and the like.

At present, when a monitor of a personal computer is stopped and a predetermined time passes, a screen saver is activated, and a video input in advance appears to protect the monitor. The control method, means, and purpose are different from those of the present invention, and the calculation of time starts from the time when the operation of the personal computer is stopped. Conversely, the calculation of time according to the present invention starts from the time when the operation of the personal computer is started. In addition, general screen
The screen used for the saver has only an aesthetic function, and cannot provide an exercise that relieves eye fatigue by using the screen as in the present invention.

In order to continuously exercise the eyes and increase the amount of the exercise, the screen for the exercise for alleviating the eyestrain is gradually or quickly moved away from the monitor screen, and / or It is preferable to have a screen to enter. As shown in FIG. 2, a picture (12) of the target is provided near the monitor (1), and when the screen (11) for alleviating eye fatigue moves away from the screen, the picture (12) of the target is drawn along the inertia trajectory. The eye movement may be extended assuming that the condition (12) is reached. For example, using a rabbit (not shown) for a picture of a target, a hawk chases the rabbit on the monitor screen that relieves eye fatigue displayed on the monitor, and when the rabbit leaves the screen, On the extension is the picture of the target. When the hawk leaves the rabbit, the rabbit may reappear on the screen.

As another embodiment, there is a view of a hawk or a shark viewed from the viewpoint (view of Eag 1e's eyes) created by computer software. As shown in Fig. 2, an image of a hawk jumping up high and looking down on the ground from a distance (21), and as shown in Fig. 3, an image of a hawk finding a prey such as a mouse (22) and descending and attacking, figure An image when flying toward the sun (23) as shown in FIG. 4 and an image when passing through a forest (24) and the like as shown in FIG. 5 are simulated. Further, other environments may be simulated, and BGM (Back ground music) may be played in accordance with them to ease the tension of the user.

In another embodiment, when the screen of the monitor is the screen (3) as shown in FIG. 6 during operation of the personal computer, when the user selects a motion for alleviating eye fatigue and issues a command. As shown in FIGS. 7 and 8, the screen (3) enters the nature background screen (31) while gradually reducing and gradually disappears. At this time, there is a picture (12) on the wall near the extension of the disappearing screen as shown in FIG.
2) is a chart used to measure general visual acuity, and allows a user to check whether his / her visual acuity has deteriorated.
Further, as shown in FIG. 10, the screen (3) shown in FIG.
Gradually enlarges (the image of a general personal computer is changed instantaneously), and the focus of the user's eyes may be adjusted. The screen gradually changes the brightness as shown in FIG.
The pupil of the user may be enlarged or reduced.

[0019]

As described above, the present invention exercises all the muscles around the eyes of the user of the personal computer on a regular basis,
Eye fatigue can be alleviated, and eye injury due to long-term operation of a personal computer or the like can be prevented by the vertical and horizontal movements of the eyeball, the focus adjustment of the eyes, and the expansion and contraction movements of the iris membrane.
