Description

Eye circuit diagram measurer of focal lens and circuit diagram measuring method using same

The present invention relates to an apparatus and a method for measuring a near-field diagram of a focal lens user, and more particularly, a main body part placed on a flat surface such as a desk to maintain a stable state of the measuring device, and the main body part. A circuit diagram measuring unit which is hinged to the body and rotates about an end face of the main body, wherein the circuit diagram measuring unit includes an image measuring unit, a light emitting unit and a USB connection unit; It is cheaper, simpler, and more accurate by using the eye line diagram measuring instrument of the eye lens, which consists of a pair of left and right, and a circuit measuring gauge attached to the demonstration lens or the focus lens. The present invention relates to an eyeball contour meter of a focal lens, and a circuit diagram measuring method using the same.

In general, the middle-aged people lose their elasticity with age, so when you look at small letters or books or newspapers at a close distance, you will have to move away from the eyes to see the objects. This phenomenon is caused by the presbyopia of the eyes from the early 40's, which causes a lot of inconveniences for the near field work of middle-aged people. Once the presbyopia starts, the glasses should be used, but there is a limited distance to see and can see only near, and there is a lot of inconvenience to always carry the glasses.

There are many kinds of these glasses, such as magnifying glass, bifocal lens, trifocal lens, and focal lens, but the focal lens of this type has long distance to the upper part, medium distance to the middle part, and lower part. Because it is designed to look at close distance, it is convenient to see both near and long distances with just one lens, and it is easy to see.With focus lens, it is necessary to alternate between two glasses and always have to carry It is fundamentally able to solve the inconvenience, and furthermore, the appearance of the magnifier in the near part is not displayed at all because of the advantage that the world's demand for focus lens is gradually increasing.

However, when the user of the near eye glasses observes the near field, the line diagram of the near eye (line distance: the distance the eye moves downward to see the near object) according to the individual's near work environment, purpose, and reading habits. They are all differently formed. It is very important to accurately measure the line distance of near eyeballs because they are unique dimensions of individuals who have been habitualized from childhood to middle age. In particular, in a single lens, which is designed to see both near and far distances, the importance of prescribing the focal lens can be overemphasized.

However, since the focusing lens was first developed in 1959, expensive equipment with various types of functions has been developed to precisely prescribe the user of the focusing lens. No device has been developed to date. FIG. 1 illustrates a generalized eye point gauge of a progressive progressive lens of a conventional progressive lens, and a conventional eye point gauge of a progressive stage is standardized as 12 mm, 16 mm, 17 mm, and 18 mm. FIG. 2 shows a situation in which a user of a focal lens is prescribed according to the gauge. Therefore, if the user's near-circuit diagram of the depressed focal lens is at 12 mm, an accurate depressed focal lens prescription can be made. There is a significant inconvenience of having to prescribe a focal focal lens that is mm, and have to move the user's face or eyes to fit the focal focal lens that does not suit him.

Korean Patent No. 0566034, filed on March 18, 2003, discloses an optometry test tool. As shown in FIG. 2, the conventional optometry test tool is configured to be worn by a consumer by mounting a circular-focal focus lens through a clip on a front surface of an eyeglass worn by a consumer. There are many problems in the field and it is rarely used in the field. The conventional optometry test tool is placed on the consumer's existing eyeglasses because the focus lens is overlapped and worn, so that the conventional eyeglasses of the consumer are not focused on each other when the size is larger or smaller than that of the eyepiece. Because the test lens cannot be put on and the ophthalmic ophthalmic lens is circular, when the consumer puts it on and walks on it, there is a problem that the ophthalmic ophthalmic lens is rotated, so that it is impossible to make an accurate trial. In addition, in the case of a large distance of the pupil, the wearable lens is placed on the ophthalmic test tool by moving the lens outward. If the lens is out of the test tool There are frequent breaks or does not have the correct tests done problem. In addition, the conventional optometry test tool has a disadvantage in that it is very inconvenient to wear because it is frequently caused to be slightly crooked because it is mounted through a clip when mounted on the front of the glasses worn by the consumer.

Patent Application No. 10-2008-25726 filed March 20, 2008 in order to solve the problems with the conventional optometry test tool discloses a dedicated spectacles for the ophthalmic lens. However, as shown in FIG. 3, since the test eyeglasses for the conventional tachute focus lens are attached to the main frame and the auxiliary frame by the magnet, it is necessary to select the tachkin focus lens that is most suitable for the user while continuously changing the auxiliary frame. As a result, the focal lens user cannot realistically solve the fundamental problem.

The present invention has been made to solve the problems of the conventional techniques, and in the apparatus for measuring the eye circuit diagram of a focal lens user, the eye circuit diagram apparatus is placed on a flat surface such as a desk. A main body part for maintaining a stable state of the measuring device, and a circuit diagram measuring part which is hinged to the main body part and is rotated based on an end surface of the main body part, and the circuit diagram measuring part includes an image measuring part; A mobile circuit diagram measuring device including a light emitting part and a USB connection part; A pair of left and right pairs of eyeball circuit diagrams are provided for measuring the lens attached to the demonstration lens or the focal lens. It is an object of the present invention to be able to measure the eye line diagram of a multifocal lens user.

In another aspect, the present invention provides a method for measuring the eye line diagram of a user with a focal lens, wherein the method for measuring eyeball is (a) in accordance with the original eye point of the focal lens user. A first step of attaching the circuit diagram measurement gauge on the lens or the focal lens; (b) The user who wears the demo lens with the circuit diagram measuring gauge or the focal lens has a main body of the mobile circuit diagram measuring device on a flat surface such as a desk, and rotates the circuit diagram measuring part according to his short-range working environment. A second step of looking at the image measuring unit; a third step of capturing an image through an image measuring unit of a mobile circuit diagram measuring device adapted to a user's own working environment; (d) a fourth step of measuring a near eye circuit diagram of the user through the photographed image on a display screen; (e) a fifth step of prescribing a dilated focal lens according to the near eye circumference of the user, measured through the above steps. It aims to make it easier to measure the eye circuit diagram of a focal lens user.

Although the conventional equipment related to the conventional focal lens is expensive equipment of several million won to tens of thousands of won or more, it has only a simple function of measuring distance (Purple Distance) and near-field PD. It was only equipment that showed how to use the focus lens. However, the apparatus for measuring the eye circuit diagram of the user of the push-down lens according to the present invention and the circuit diagram measuring method using the same solve the problems that the conventional techniques as described above are not solved and can be used more cheaply and simply. There is an advantage in that it is possible to measure the near-circuit diagram of the focus lens user, and because the exact near-circuit diagram of an individual can be measured, the satisfaction of the defocus lens is very high.
