Description

Technical Field

[0001] It belongs to the field of science popularization simulation experience. Background Technology

[0002] This invention allows users to experience the sensations of visual impairment for educational simulation. The simulation provides a direct experience, enabling participants to empathize with and understand the feelings of patients. It can also be used as a training subject for nursing staff. Summary of the Invention

[0003] This invention relates to a specially designed pair of glasses, comprising a main board and two eyepiece frames, one for each eye and one for the right. Each eyepiece frame is rotatably connected to the main board via a rotating mechanism, allowing the user to manually rotate it around its central axis. The eyepiece frame consists of an outer frame and an inner frame, which can be fastened together. The inner frame has an outward-flared edge at the bottom. The main board has two eyepiece shaft holes corresponding to the left and right eye positions. The rotating mechanism is installed such that the inner frame is inserted into the eyepiece shaft hole from the bottom of the main board, with the upper part of the inner frame protruding from the top of the main board. The upper part of the inner frame is fastened and fixed to the outer frame, allowing the inner frame to rotate around its central axis within the eyepiece shaft hole. The rotating mechanism also includes a positioning structure that fixes the eyepiece frame in a selected position after rotation. This positioning structure includes a spring bead installed on the wall of the eyepiece shaft hole, and continuous grooves on the outer wall of the inner frame. The grooves cooperate with the spring bead to achieve the positioning function.

[0004] Special lenses can be installed inside the eyepiece frame. The eyepiece frame can be manually rotated around its central axis. It contains one of two special lenses: 1. A lens simulating strabismus, where a micro-prism array refracts light to simulate strabismus and diplopia; 2. A lens simulating cataracts, a single-sided frosted lens where a small portion of the frosted surface is polished, or resin is dripped onto the frosted surface to fill it, forming a mirror-like layer that becomes permanently transparent after solidification. This simulates the visual effect of cataracts. When the strabismus / diplopia lens is installed, rotating the lens to adjust the direction of refraction allows users to experience the sensation of strabismus / diplopia from different angles. When the cataract lens is installed, users can experience the visual sensation of cataracts. Attached Figure Description

[0007] 3a. Strabismus lenses are made of transparent material. One side of the lens is flat, while the other side has multiple rows of prisms with triangular cross-sections arranged side-by-side, allowing for refraction. The eye sees a strabismus (crossed eyes) through these lenses. 3b. Cataract lenses have a large area of ​​translucent frosted glass to simulate the visual field loss, with a small portion being a mirror-like translucent surface to simulate the remaining visual field. This simulates the visual experience of cataracts. Manufacturing method: Select a single-sided frosted lens. Polish a small portion of the frosted surface, or drip a transparent liquid material such as resin onto the frosted surface, filling this area with resin to form a mirror. After solidification, it becomes permanently transparent.

[0008] During installation, first align the four clips 9 on the inner frame of the eyepiece with the four clip channels 8 on the eyepiece shaft hole 7 and insert them until the upper clips 9 of the inner frame of the eyepiece are exposed (as shown in the attached diagram). Figure 3 (As shown on the right half), the outer diameter of the bottom flange of the inner eyepiece frame is larger than the eyepiece shaft hole to prevent detachment. Special lens 3 is inserted into the outer eyepiece frame (as shown in the attached image). Figure 3 (As shown on the right half), then align the slot on the outer frame of the eyepiece with the clip on the inner frame of the eyepiece and press to install and lock it in place (as shown in the attached image). Figure 4 (As shown). The eyepiece frame can be rotated by hand. The positioning spring bead 11 is aligned with the positioning groove 12 to achieve positioning during rotation. There is a triangular arrow mark on the eyepiece frame. When the special lens 3a is selected, the refraction direction of the lens is consistent with the direction of the triangular arrow, representing the direction of strabismus. One lens or two lenses can be installed. When the two lenses have different strabismus directions, the visual effect of diplopia can be experienced. When the special lens is a cataract lens, rotating the eyepiece frame can experience the feeling of cloudiness in different parts of the cataract. The soft rubber frame 5 is made of soft rubber and its installation method with the main board is similar to the lens installation method of common medical goggles or swimming goggles.
