Technical Field

[0001] The utility model relates to the technical field of markers, in particular to a corneal astigmatism axis marker. Background Art

[0002] A corneal astigmatism axis marker is an instrument or device used to accurately locate the axis of astigmatism on the cornea of ​​the eye. It usually includes a specially designed instrument or marker that can help ophthalmologists or optometrists accurately determine the axis of astigmatism when measuring the degree of astigmatism in the eye.

[0003] Currently, corneal astigmatism axis markers are required during ophthalmic examinations and glasses fitting. Most of the existing corneal astigmatism axis markers can only mark the patient's astigmatism axis, and cannot measure the astigmatism degree while marking the astigmatism axis, thereby increasing the measurement time and the error rate during the test, reducing accuracy and work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that it is impossible to measure the astigmatism degree while marking the astigmatism axis, thereby increasing the measurement time and the error rate in the test process, reducing the accuracy and work efficiency, and to propose a corneal astigmatism axis marker.

[0008] A marking component is arranged on the frame and is used to mark the astigmatism axis.

[0009] In a possible design, the marking assembly includes two rotating rings respectively rotatably arranged on the inner rings of the two frames, the inner rings of the two rotating rings are fixedly provided with a turntable, the front lower halves of the two turntables are fixedly provided with a semi-annular frame, both sides of each semi-annular frame are symmetrically fixed with arrows, and the bottoms of the two semi-annular frames are fixedly provided with a shift block.

[0010] In a possible design, an annular opening is provided on the sides of the two fan-shaped brackets on the same mirror frame that are close to each other.

[0011] In a possible design, a nose pad groove is provided at the bottom of the connecting frame, a placement groove is provided at one side of the connecting frame, and a bubble level is fixedly installed inside the placement groove.

[0013] In a possible design, ear supports are slidably provided on the outside of the two frames.

[0014] In the present application, when starting to use, the two frames are unfolded, and then the frames are put on the wearer's face through the frames, and then the ear pads are slid to move the ear pads on both sides toward the ears until the ear pads are against the back of the ears to complete the wearing of the device, and then the spherical lens is taken out and placed on the fan-shaped bracket on the back side of one of the frames, and then a shielding object is placed on the fan-shaped bracket on the back side of the other frame to cover the eye at the corresponding position, so that that eye is blocked and invisible, and then the wearer looks straight ahead through the spherical lens. If it is not clear, replace the spherical lens with other degrees until it can see clearly. By replacing spherical lenses of different degrees, the wearer's corrected vision can be controlled within the range of about 0.6 to 0.7, and then the slit piece is taken out and stuck on the frame with the same position as the spherical lens, and the slit piece is located on the front side of the frame and located in the semi-ring frame. , and then let the wearer use his / her fingers to move the dial block. When the dial block is moved, it drives the turntable on the frame to rotate. When the turntable rotates, it drives the slit piece in the semi-ring frame to rotate synchronously. The wearer adjusts the angle of the slit piece by himself / herself, and allows him / her to adjust it to the clearest position. Then stop moving the dial block, and then observe and record the position of the scale line pointed by the arrow to obtain the wearer's astigmatism axis position. At the same time, add spherical lenses of different degrees at the clearest position until the best vision is achieved, and then record the degree of the spherical lens, and then move the dial block to rotate the slit piece until the position of the slit piece is the most blurred position, and then replace the spherical lens until the slit piece is replaced to the position with the clearest vision, and then record the degree of the spherical lens, and then subtract the two recorded degrees to obtain the difference between the two values, so as to obtain the degree of the wearer's astigmatism.

The slit sheet is located at the front side of the frame and in the semi-ring frame. Then the wearer can turn the dial block by finger. The dial block drives the turntable on the frame to rotate while turning. The turntable drives the slit sheet in the semi-ring frame to rotate synchronously while rotating. The wearer can adjust the angle of the slit sheet by rotating it to the clearest position. Then the dial block is stopped. Then the position of the scale line pointed by the arrow is observed and recorded to obtain the wearer's astigmatism axis position, so that the astigmatism axis position can be conveniently and accurately obtained, reducing the uncertainty caused by errors and subjective judgments.

[0017] In the utility model, through the cooperation between the marking component and the fan-shaped bracket, at the position where the vision is clearest, by adding or replacing spherical lenses of different degrees on the fan-shaped bracket until the best vision is achieved, the degree of the spherical lens is recorded, and then the dial block is turned to rotate the slit plate until the position of the slit plate is the position where the vision is most blurred, and then the spherical lens is replaced until the spherical lens is replaced to the position where the vision is clearest, and then the degree of the spherical lens is recorded, and then the difference between the two recorded degrees is subtracted to obtain the difference between the two values, and the degree of astigmatism of the wearer is obtained. The measurement of the degree of astigmatism can be quickly completed when marking the axis position, saving time and reducing possible errors in the test process, improving the accuracy of astigmatism measurement, and improving work efficiency;

[0018] The utility model can not only conveniently and accurately obtain the axial position of astigmatism and reduce the uncertainty caused by errors and subjective judgments through the arrangement of the marking component and the fan-shaped bracket, but also quickly complete the measurement of the astigmatism degree, save time and reduce possible errors in the test process, thereby improving the accuracy of astigmatism degree measurement and improving work efficiency.
