BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus, a method, and a recording medium on which a program can be expressed, which can express a visual field when wearing glasses.

[0002]

2. Description of the Related Art When purchasing spectacles, a user selects a spectacle lens and a spectacle frame, and a combination thereof is delivered. When selecting a spectacle lens, wear a lens prepared as a sample in a spectacle shop, check the appearance, and select the one that seems suitable for yourself while listening to the explanation of the clerk. Then, spectacles with the selected spectacle lens mounted on the separately selected spectacle frame are produced and delivered to the user.

[0003]

In this way, the user selects and purchases spectacles which seem to be suitable for himself, but what the field of view looks like when wearing spectacles is actually I don't know until I put on my glasses. There are a limited number of eyeglass lenses that are available as samples in stores, and lenses that are not available as samples, or lenses that have properties intermediate to those provided as samples, are suitable for users. If it is determined that the eyeglasses are present, the characteristics of the eyeglasses are not actually known until the user actually wears the glasses that were actually delivered. In particular, a progressive area with a distance area suitable for viewing objects at a long distance, a near area suitable for viewing objects at a short distance, and an intermediate area in which the refractive power changes gradually between them. When selecting a multifocal lens, the properties of the progressive surface differ depending on the distance and near power, and whether the focus is on distance or near, and so on. I do not know if it looks like. Further, it is difficult even for a clerk at an eyeglass store to explain the state of the visual field to a user who has not actually used the progressive lens. Further, the prescription of the spectacle lens is not limited to the power, but includes astigmatism and addition for a progressive lens. For this reason, it is impossible to grasp everything only by the explanation of the sample or the clerk.

It has been studied to display a visual field image that can be seen with glasses on a personal computer or the like, and to select the glasses suitable for oneself by simulating the state of wearing glasses. However, in a progressive multifocal lens, the characteristics are different depending on the distance, near, or intermediate regions of the spectacle lens, and the region that is clearly visible and the region that is blurred changes according to the distance to the object. It is difficult to clearly show the characteristics to the user only by showing the visual field image corresponding to the distance.

Therefore, in the present invention, an eyeglass viewing experience apparatus, experience method, and experience program capable of clearly displaying to a user differences in the characteristics of spectacle lenses whose characteristics differ depending on the distance to the object are recorded. It is an object of the present invention to provide a recorded medium. Then, the user grasps in advance how to see when using spectacle lenses with different characteristics for each distance, such as a progressive multifocal lens, and selects a spectacle lens suitable for himself, so that a comfortable visual field can be obtained. It is intended to be.

[0006]

For this reason, in the present invention, a field-of-view image viewed with glasses is displayed on the entire spectacle lens, and the field-of-view image of the entire spectacle lens corresponding to the distance to the object is switched. The display makes it easy to see how the appearance changes according to the distance to the object or through which area of the eyeglass lens to obtain a clear visual field, making it easier for the user to grasp the characteristics of the eyeglasses. Become.

Further, there is provided an output method for outputting a field-of-view image obtained by wearing a pair of spectacles, which is a field-of-view image obtained by viewing an object at a specific distance through the entire spectacle lens. By providing a computer-readable recording medium in which a program having instructions capable of executing the program is recorded, a visual field experience system for spectacles can be realized using a general-purpose information processing device such as a personal computer. In addition, it is possible to provide an eyeglass viewing experience service having a similar function on a homepage accessible via the Internet. Therefore, a simple information processing device such as a personal computer is used to project a visual field image corresponding to the distance on a display or a head-mounted display, and to simulate the situation when the user actually wears glasses and looks at a specific distance. be able to.
Of course, a program capable of constructing the visual field experience system according to the present invention can be supplied via a computer network such as the Internet.

In the visual field experience apparatus, the visual field experience method and the program according to the present invention, not only a visual field image corresponding to one specific distance is output but also a visual field image corresponding to a plurality of different distances to an object. Or a first view image group including the first view image group or a second view image group including the second view image group corresponding to the distance between the different types of spectacle lenses. It is desirable to be able to switch and output. By selecting and displaying the field-of-view images with different distances, the user can understand how the objects with different distances look. Further, by comparing the visual field images corresponding to the same distance with different types of spectacle lenses, it is possible to easily convey the characteristics of the spectacle lenses to the user. Therefore, the user can fully understand the characteristics of the spectacle lens and select a spectacle lens suitable for himself.

Further, by outputting a position display of a specific area of the spectacle lens from which a visual field image corresponding to the output distance is obtained, the visual field image corresponding to which distance or which specific area is viewed. It is possible to clearly express whether the image is a visual field image.
