Description

Method, program and device for measuring ease of adjustment and presenting potential for improvement in visual acuity

The present invention relates to a method and program for measuring accommodative ease and suggesting the possibility of improving visual acuity.

Accommodative ease refers to the ability of the accommodative system to respond to rapid changes in accommodative stimuli.

To see near objects, the lens must be thicker, and to see far objects, the lens must be thinner.

A person with normal accommodative ability sees a near object or a distant object immediately, but a person with insufficient accommodative ability feels a lot of discomfort because the object is not immediately clear.

Accommodation means the power of adjustment, and even if the accommodative power is normal, if the ease of adjustment is insufficient, there is an inconvenience that the object is not immediately clear when looking at it, apart from the accommodative force.

Therefore, accommodative easiness also requires a separate measurement, and accommodative easiness training is also required if accommodative easiness is insufficient.

1 is a diagram for explaining a method for measuring adjustability and presenting the possibility of improving visual acuity according to an embodiment of the present invention.

2 is a diagram for explaining the configuration of a display screen providing a comparison target along with a measurement target.

Referring to FIG. 1 , the method for measuring accommodative ease and presenting the possibility of improving visual acuity includes receiving a request for measuring accommodative ease of eyes from a user (S100) by a computer, and requesting the computer to place a lens subscription device in front of a specific eye of the user. and requesting arrangement of a user terminal including a display unit (S200), obtaining an adaptation time from non-emetropia to emmetropia by a computer (S300), measuring the adaptation time by a computer, matching it with a change in subscription lens, and storing the result A step (S400) and a step (S500) of calculating the user's ease of adjustment by the computer.

The arrangement of the user terminal is to fix the position for measuring the ease of adjustment while the user is holding the user terminal, and the measurement subscription lens is selected from a plurality of subscription lenses arranged in the lens subscription device or preset, As a specific lens for measuring ease of adjustment, it is placed in front of the user's specific eyeball.

As an example, the lens subscription device may be provided in a form that can be worn by a user (eg, in the form of glasses). In the case of a wearable type lens subscription device, when the computer requests the user to place the lens subscription device in front of the user's particular eye, the user can fulfill the computer's request by wearing the lens subscription device.

In another embodiment, the lens subscription device may be provided in a mounted form. In the case where the lens subscription device is provided in a mounted form, when the computer requests the user to place the lens subscription device in front of the user's specific eyeball, the user's eyes are placed close to the lens subscription device, which is mounted, so that the computer requests the computer to place the lens subscription device. can be performed.

Also, the lens subscription device includes a distance sensor for measuring a distance between the lens subscription device and the user terminal.

The distance sensor measures the distance between the lens subscription device and the user terminal, and may be used based on the measured distance between the lens subscription device and the user terminal in measuring eyesight, measuring accommodative force, and providing a measurement target, which will be described later.

In addition, the user can perform not only measurement of accommodative ease, but also vision measurement, vision improvement training, accommodative force measurement, accommodative easiness measurement, and accommodative easiness training using one lens subscription device by using the same lens subscription device.

The computer requests the user to place the lens subscription device in front of the user's specific eyeball, and requesting the placement of the user terminal including the display unit (S200), disposing the lens subscription device and the user terminal, and disposing the lens subscription device and the user terminal. As the position adjustment, the user holds the user terminal in a state in which the lens subscription device is placed in front of a specific eyeball and places the user terminal within the movable range of the arm.

Acquiring the adaptation time from non-emetropia to emmetropia by the computer (S300) is the adaptation time from non-emetropia to emmetropia by providing a measurement target and changing a measurement subscription lens among a plurality of subscription lenses arranged in the lens subscription device. is to obtain

When the user's eyes view a target through a lens that is changed, it takes time to adapt from a non-emetropic to clearly visible emmetropia.

Accommodative ease is calculated based on the adaptation time from non-emetropic to emmetropic, and it is necessary to acquire the adaptation time.

As a method of determining whether the non-emetropia has changed to emmetropia, the computer may receive a feedback input from the user.

That is, an input of feedback is received from the user at a boundary point between the emmetropic range and the non-emmetropic range.

Accurate adaptation time from non-emetropic to emmetropic eye can be measured only when the user's feedback input is received at the boundary point between the emmetropic range and the non-emmetropic range.

The feedback is input by at least one method of motion or input on a user terminal.

Motion types include all feedback input methods using motion at a corresponding position, including a hold method, a method of moving the device in a direction different from the moving direction, and the like.

Methods of directly inputting on the user terminal include all methods of directly inputting on the user terminal at the corresponding location, including a method of inputting using touch manipulation, a method of inputting by dragging on the user terminal, and the like. do.

In addition, the step of acquiring the adaptation time from the non-emmetropic to the emmetropic (S300) by the computer includes providing a measurement target, but providing a comparison target that looks unclear together with the measurement target.

Referring to FIG. 2 , a measurement target 10 and a comparison target 20 are presented together on a screen displaying a target for measuring ease of adjustment.

In measuring accommodative ease, it may be difficult for the user to accurately determine the range of emmetropia and non-emetropia because it is ambiguous.

At this time, the computer provides a comparison target 20 that looks unclear as the degree of blur seen when the non-emetropia is seen together with the measurement target 10.

When measuring the ease of adjustment, the user can clearly determine the boundary between the non-emmetropic eye and the emmetropic eye by providing the measurement target 10 together with the comparison target 20 for determining whether or not the user has an emmetropia.

As a result, accommodative ease can be accurately measured by clearly determining the boundary between non-emetropia and emmetropia.

In the step (S400) of matching and storing the adaptation time with the change of the measurement subscription lens by the computer, the computer stores the adaptation time by matching it with the change of the measurement subscription lens, but the adaptation time is the same as when the diopter is changed to a lens with an increasing diopter. When changing to a lens with a decreasing diopter, it is divided and stored separately.

Instead of simply calculating the adaptation time from non-emetropia to emmetropia when the lens is changed, this is not directly derived as adjustment ease. Each adaptation time when changing to a decreasing lens is calculated, and the adaptation time is matched with the changed state of the measured subscription lens and stored.

That is, based on the change condition of how the diopter changes, adaptation times are matched and stored.

As for ease of adjustment, each result can be different when changing to a lens with increasing diopter and when changing to a lens with decreasing diopter, so each adaptation time is matched and stored, and ease of adjustment is derived using this. By calculating only the adaptation time when the lens is changed, it is possible to derive a more accurate analysis result than that derived by ease of adjustment.

In addition, the step of allowing the computer to match and store the adaptation time with the change in the measurement subscription lens (S400) further includes matching and storing the adaptation time according to the difference between the diopter of the lens before the change and the diopter of the lens after the change.

Not only whether the change was made to a lens with increasing diopter or a lens with decreasing diopter, but also the difference in diopter between the lens before and after the change is matched with the adaptation time and stored.

Based on the diopter difference value, a more accurate analysis result of ease of adjustment can be derived, and the matching of the diopter difference value and adaptation time can be the basis for calculating the possibility of expanding the visual range when presenting a vision improvement plan. .

As described above, in order to determine whether the diopter is changed to a lens with increasing diopter or a lens with reduced diopter, and how much the diopter difference value is between the lens before and after the change, the measurement lens is measured on the lens subscription device. It is necessary to derive the diopter value, etc.

A method of automatically deriving the diopter value of a measurement lens includes an adaptation time storage step when a measurement subscription lens among a plurality of subscription lenses is placed in front of a user's specific eyeball through rotation or movement of the plurality of subscription lenses by the lens subscription device. (S400) The computer measures each subscription based on at least one of the rotation or movement distance of the plurality of subscription lenses and the number of rotations or movement of the plurality of subscription lenses and the diopter value of the plurality of subscription lenses previously arranged. It is to check the diopter value for the lens, match it with the adaptation time, and save it.

The lens subscription device includes a lens unit and is provided so that a plurality of subscription lenses can be rotated or moved. Hardware related thereto will be described later with reference to FIGS. 5 and 6 .

3 is a diagram for explaining a method of calculating a clear range according to an embodiment of the present invention.

Referring to FIG. 3 , the method for measuring accommodative ease and suggesting the possibility of improving visual acuity according to an embodiment of the present invention further includes a step of calculating, by a computer, a current visual field (S600).

The step of calculating the current visual field by the computer (S600) is to measure the user's home visual acuity and accommodative power using the lens subscription device and the user terminal to calculate the current visual field.

The origin of the visual range can be obtained through the measurement of the visual acuity at the origin, and the near point of the visual range can be obtained through the measurement of accommodative power.

Accordingly, the current visual field can be calculated according to the acquisition of the origin and near point so that the origin and near point can be obtained by measuring the origin visual acuity and accommodative power.

A method of measuring a user's acuity acuity using a lens subscription device and a user terminal includes the steps of a computer receiving a visual acuity measurement request from a user, the computer requesting the user to place the lens subscription device in front of the user's specific eyeball, and displaying the The step of requesting arrangement of user terminals including the part, the step of correcting the size of the target by the computer, and the step of displaying the target of the corrected size on the user terminal by the computer.

In the step of correcting the size of the target by the computer, the computer corrects the size of the target based on the distance between the lens subscription device and the user terminal and the magnification of the subscription lens disposed in the lens subscription device.

In the step of correcting the size of the target, the corrected target based on the distance and the magnification of the subscription lens is an accurate vision measurement value such as the vision measured at a distance of 5 m when the eyesight is measured at the distance between the user terminal and the lens subscription device. It is a table of the size to derive.

Therefore, by measuring the visual acuity with the size of the calibrated target, it is possible to derive an accurate visual acuity measurement value, such as the visual acuity measured at a distance of 5 m even at a short distance (the distance between the lens subscription device and the user terminal).

A method for measuring a user's accommodative power using a lens subscription device and a user terminal includes receiving a request for measuring the accommodative power of an eye from a user by a computer, requesting the computer to place a lens subscription device in front of a specific eye of the user, Requesting arrangement of a user terminal including a display unit, and as the user moves the user terminal so that the distance between the user terminal and the lens subscription device becomes farther or closer, the computer determines the distance between the lens subscription device and the user terminal and the lens and correcting the size of the measurement target based on the magnification of the measurement subscription lens disposed in the subscription device.

The user can easily measure the adjustment force by placing the lens subscription device in front of a specific eyeball and adjusting the distance to the user terminal using a distance sensor included in the lens subscription device.

As described above, the origin and near point are acquired through the measurement of the user's acuity and accommodative power using the lens subscription device and the user terminal, and the current visual range of the user can be calculated by the origin and near point.

When the current visual range is calculated through the measurement of the user's visual acuity, the measurement target provided in the step of acquiring the adaptation time (S300) is presented with a target size corresponding to the visual acuity lower than the user's visual acuity by a predetermined visual acuity value. do.

In the measurement of ease of adjustment, if the target is not confirmed due to the influence of eyesight, the result of measuring ease of adjustment cannot be accurately derived.

Therefore, when measuring ease of adjustment, a target corresponding to a visual acuity that is worse than the user's visual acuity by a certain level is provided in order to exclude the effect of visual acuity.

However, if too large a target is provided, a result of not recognizing a sharpness change according to a lens diopter change may be derived.

Within a predetermined range, a target corresponding to the visual acuity lower than the user's visual acuity by a certain level is provided.

For example, if the user's visual acuity is 1.0, a target having a size corresponding to a visual acuity of 0.8 is provided to the user when measuring ease of adjustment.

When the ease of adjustment is measured by applying the size of the target corresponding to the low visual acuity of about 0.2, it has the effect of excluding the target from not being confirmed due to the effect of visual acuity, and the change in sharpness according to the change in lens diopter is also easy to recognize.

The above-mentioned low visual acuity of about 0.2 is only an example, and all that corresponds to a low visual acuity that is easy to recognize the change in sharpness according to the lens diopter change while excluding the effect of the visual acuity is included.

Accordingly, a target having a size corresponding to a low visual acuity as low as a predetermined visual acuity value, which is a low visual acuity to the extent that it is easy to perceive a change in sharpness according to a lens diopter change while excluding the effect of visual acuity, is presented for measuring ease of adjustment.

In the step of requesting placement of the user terminal (S200), the position where the user terminal is placed corresponds to a position farther than the user's near point by a predetermined distance.

In measuring the accommodative ease, if the accommodative ease is measured at a position closer than the near point, the accommodative ease measurement is performed in an area that cannot be seen in an emmetropic state due to lack of accommodative power.

When measuring the ease of adjustment, an accurate measurement value for the ease of adjustment can be derived only when the measurement is performed while excluding other factors except for the ease of adjustment. Can not.

Therefore, in order to exclude the factor due to lack of accommodative force, the accommodative force must be measured at a position farther than the near point by a predetermined distance within the user's visual range.

4 is a diagram for explaining a method for measuring ease of adjustment and calculating a possibility of improving visual acuity according to an embodiment of the present invention.

Referring to FIG. 4 , the method for measuring the ease of adjustment and presenting the possibility of improving visual acuity according to an embodiment of the present invention further includes a step (S700) of allowing a computer to calculate the possibility of improving the visual field and the possibility of improving the visual acuity and presenting them to the user. do.

In step S700, in which the computer calculates the possibility of expanding the visual range and the possibility of improving visual acuity and presents it to the user, the possibility of expanding the visual field and the possibility of improving the visual acuity are calculated and presented to the user based on the ease of adjustment of the user and the current visual range. is to do

In the clear range, the near point may appear farther away when the adjusting muscle that changes from the thin lens to thick is stiffened, and the origin can appear closer when the muscle that changes from the thick lens to thin is stiff. As a result, The explicit range may be calculated to be narrower than the range originally possessed by the user.

Based on the measured current visual range of the user and the ease of adjustment of the user, the possibility of expanding the visual range and improving the visual acuity can be calculated.

The possibility of extending the visual range corresponds to the possibility that the origin becomes further away and/or the possibility that the near point becomes closer, and the possibility of visual acuity improvement corresponds to the possibility that the origin becomes further away.

Based on the measured current visual range of the user and the ease of adjustment of the user, the method of calculating the possibility of expanding the visual range and the possibility of improving visual acuity is ~~~~~~~~~~~.

As described above, the user's origin visual acuity and accommodative power value obtained using the lens subscription device and the user terminal, and the adaptation time matched with the diopter value of the measured subscription lens before and after each change are stored in the user terminal or computer there is.

Therefore, the home visual acuity and accommodative power values, which are the user's conditions, and the adaptation time according to each lens change acquired for measuring accommodative ease are established as learning data, and the possibility of expanding the visual field range, the possibility of improving the visual acuity, and the specification by using the learning data It is possible to build a learning model capable of deriving related result values such as the possibility of range reduction and the possibility of visual acuity reduction.
