Description

Artificial artificial eye for replacing human eye for ophthalmologic equipment examination

Technical Field

The utility model relates to an ophthalmology equipment inspection is with artificial eye who replaces people's eye belongs to optical equipment technical field.

Background

With the continuous improvement of the living standard of human, the human faces more and more ophthalmic diseases. Various types of ophthalmic examination devices have been developed, such as fundus cameras, perimeter, or corneal mappers. After mass production of these ophthalmic test devices, quality tests are required for their function and accuracy.

The eye is now commonly used to test ophthalmic examination devices, but because of the large number of ophthalmic examination devices. If human eyes are used for testing the ophthalmologic equipment, the labor cost is high, a large burden can be caused to the human eyes, and meanwhile, the human eyes are fatigued after working for a long time, and the accuracy of a detection result is influenced to a certain extent. Therefore, an artificial eye model capable of replacing human eyes is urgently needed to replace the human eyes to complete the detection of the optical instruments.

The eye ground of the existing eye simulation device is generally a curved surface, and the target of the eye ground is not convenient to replace because the target is printed on the curved surface and is far from being printed on a flat plate conveniently. The periphery of the eyeground has no perception judgment for light energy. This results in that the light amount around the field of view is not perceived as a human eye, and then the judgment of brightness and darkness can be given.

SUMMERY OF THE UTILITY MODEL

To the above technical problem, an object of the utility model is to provide an ophthalmic devices inspection is with artificial eye who replaces people's eye can be used for replacing people's eye to detect optical instrument, makes simply.

In order to realize the purpose, the technical scheme of the utility model is that: an artificial eye for ocular device examination which replaces a human eye, characterized in that: the simulated eye cornea, the simulated pupil, the optical lens group and the simulated plane eye ground are sequentially arranged from left to right, the total focal length value of the optical lens group is 10mm-100mm, a photoelectric sensor capable of detecting the ambient light illumination is distributed on the simulated plane eye ground, and a target pattern layer is arranged on the simulated plane eye ground.

Preferably: the optical lens group comprises a first focusing lens arranged close to the simulated pupil and a diverging lens arranged close to the simulated plane eye ground, a second focusing lens is further arranged between the diverging lens and the first focusing lens, and the total focal length value of the three lenses is 10mm-100 mm. The required lenses are few, the manufacturing cost is low, and good effects can be achieved.

In the scheme, the method comprises the following steps: photoelectric sensors are respectively arranged in the middles of the upper, lower, left and right sides of the simulated plane fundus oculi. The ambient light illumination can be better and more effectively detected.

In the scheme, the method comprises the following steps: the target pattern layer is a target capable of reading a value.

The utility model discloses following beneficial effect has: the utility model discloses it is easier to reform transform into the plane (the eye ground of people and animal is not the plane but the curved surface) to the people's eye ground through optical design, installs the mark target additional on simulation plane eye ground. Just the utility model discloses install the induction system that can detect surrounding illuminance additional inside the artificial eye, the eye ground has the perception judgement to light energy all around. The light quantity around the visual field can be perceived like human eyes, and then the brightness judgment is given. The method can replace human eyes when the ophthalmic equipment is qualified or not, and the manufacturing is convenient and rapid.
