[0040] like Figure 1-9 As shown, the present invention provides a test lens for correcting amblyopia, comprising: a carrier 1 having multiple spaced-apart light-transmitting portions 11; an attachment 2 disposed on the light-transmitting portions 11 for blurring the light-transmitting portions 11 to suppress the patient's dominant eye vision; different light-transmitting portions 11 are provided with corresponding attachments 2 having different suppression levels, and the suppression level of the attachments 2 gradually increases along the arrangement direction of the multiple light-transmitting portions 11. The present invention provides multiple attachments 2 with different suppression levels on the carrier 1 to meet the vision needs of different patients and facilitate vision testing. Furthermore, the integration of multiple attachments 2 with different suppression levels on a single carrier 1 achieves structural integration, facilitates user operation, and improves testing efficiency.

[0041] like Figure 4 、 5 As shown, the light-transmitting portion 11 comprises a transparent member 111, and the additional member 2 comprises a suppressing film 21. An adhesive member is disposed between the transparent member 111 and the suppressing film 21, and the suppressing film 21 is connected to the transparent member 111 via the adhesive member. The present invention utilizes the concave and convex texture of the suppressing film 21 to create blurred vision, thereby suppressing the dominant eye and forcing the amblyopic eye to see, thereby achieving the desired vision correction effect. Furthermore, the suppressing film 21 is a colorless film. Directly adhering the suppressing film 21 to the transparent member 111 makes it more aesthetically pleasing and easier to use than traditional full-coverage eye masks.

[0042] like Figure 6 、 7 As shown, the light-transmitting portion 11 includes a light-transmitting hole 112, and the attachment 2 includes a suppressing lens 22. A snap-fit structure 17 is provided between the light-transmitting hole 112 and the suppressing lens 22, and the suppressing lens 22 is connected to the light-transmitting hole 112 via the snap-fit structure 17. The present invention achieves detachable retention of the suppressing lens 22 from the carrier 1 by snapping the suppressing lens 22 to the light-transmitting hole 112. Compared to traditional test glasses, the present invention provides greater flexibility and facilitates replacement.

[0043] Among them, an anti-slip pad is provided on the pressing lens 22 or the clamping structure 17 to increase the friction between the pressing lens 22 and the clamping structure 17, thereby preventing the pressing lens 22 from falling off and further improving the reliability of the structure.

[0044] In this embodiment, the anti-slip pad is provided on the periphery of the pressing lens 22 .

[0045] The transparent part 111 includes an arc-shaped transparent part that is protruding in the middle and concave on all sides. The arc-shaped transparent part can better adapt to the physiological structure of the eye, so that the lens matches the refractive system of the human eye, thereby obtaining more accurate vision test results to improve the amblyopia correction effect; and the arc-shaped transparent part 111 can better fit the curvature of the eyeball, improve the comfort during vision testing, and reduce the patient's eye fatigue.

[0046] like Figure 1-9 As shown, the test lens for correcting amblyopia also includes a plurality of scale marks 3, which are arranged at intervals on the carrier 1. The scale marks 3 are arranged corresponding to the attachment 2 and are used to identify the degree of suppression of the attachment 2. The degree of suppression of each attachment 2 is clearly displayed through the scale marks 3, so that the user can select the appropriate degree of suppression for vision testing according to the specific situation. At the same time, information can be recorded more conveniently to avoid test errors caused by confusion and ensure the accuracy of the test results.

[0047] like Figure 1 、2 As shown, a plurality of card slots 12 are provided on the carrier 1, and the scale mark 3 is detachably arranged on the carrier 1 through the card slots 12.
