Description

Technical Field

[0001] This invention relates to the field of eyewear, and more particularly to a contact lens wearing aid. Background Technology

[0002] People often blink reflexively when wearing glasses, making it difficult to wear contact lenses, especially scleral lenses and orthokeratology (Ortho-k) lenses. Scleral lenses are typically filled with eye drops or solutions on their concave side. If worn directly by hand, they can easily wobble and tilt during the movement, causing leakage. This leakage creates air bubbles between the eye and the lens, leading to poor vision or discomfort and affecting treatment effectiveness. Usually, the lens needs to be removed and re-inserted, which adds to the user's difficulty.

[0003] Of course, soft contact lenses are usually worn directly by hand, and if hygiene is not taken seriously, they can affect eye health and cause problems such as inflammation.

[0004] In addition, wearing contact lenses can be difficult for people with difficulty controlling their fingers, or those with conditions such as Parkinson's disease, arthritis, or stroke.

[0005] Therefore, it is necessary to provide a new technical solution to address the aforementioned problems. Summary of the Invention

[0036] Compared with the prior art, the technical solution of the present invention has at least one or more of the following beneficial effects:

[0037] This patented method facilitates lens insertion. The lens is placed on a lens holder, freeing the user's hands. The hands are used to open the eyelids, and then the eye is positioned on the lens in the holder, allowing for accurate insertion in one go. This makes insertion much easier. Scleral lenses are generally used for eye treatment and require a saline solution or eye drops. Using this assistive device makes insertion easier and more convenient. Orthokeratology (Ortho-k) lenses for children are also easier to insert, as children often struggle with the procedure and others may not be able to assist them. For users of regular soft contact lenses, who need to remove and insert them daily, this assistive device provides significant convenience. Furthermore, using the device eliminates the need to handle the lens, preventing contamination and potential eye inflammation.

[0038] The mounting rod can be detachably or non-detachably mounted on the support rod. The mounting rod acts as an adapter, facilitating the replacement of different lens holder sizes. It also allows for height adjustment, enabling users to adjust the height of the mounting rod according to their needs, whether they are adults, children, standing, or sitting, for comfortable wear. The height of the mounting rod can be adjusted by using different lengths or by incorporating a telescopic adjustment mechanism, which in turn adjusts the height of the contact lens on the lens holder.

[0039] A support section is provided to stably support the support rod, allowing it to be easily removed from the base while maintaining stable standing. The support rod is detachable for easy transport.

[0040] A limiting rib is provided to prevent the lens holder from rotating on the mounting rod. A limiting protrusion is also provided to prevent the support rod from rotating on the base, which would affect the wearing of the lens.

[0041] When in use, press the button to turn on the light source. The light emitted by the light source shines on the light guide, which focuses the scattered light emitted by the light source into a light spot or beam. The light spot or beam passes through the optical fiber, the transparent material mounting rod, and the through hole of the lens holder and shines onto the contact lens. The contact lens is placed on the arc-shaped groove of the lens holder. The user focuses the light spot or beam on the eye and moves the head to the lens holder to wear the contact lens inside the eye.

[0042] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0071] In the example, the optical fiber 22 corresponds to the through hole 12 of the lens holder 1. In the example, the optical fiber 22 and the through hole 12 of the lens holder 1 are coaxially arranged.

[0072] The base is used to stably support the auxiliary device, and its size and shape are not limited.

[0073] In a preferred embodiment, such as Figure 5-7 As shown, support rod 2 is a single, integrally connected support rod. Support rod 2 can also be formed by assembling multiple separate support rods 25, such as... Figure 1-4 As shown. Preferably, the support rod 2 is assembled from multiple sub-support rods 25, which can be connected end-to-end by thread, snap-fit, compression, etc. In the example, the support rod 2 is assembled from two sub-support rods to form a long support rod. The sub-support rods facilitate disassembly and carrying, and allow for adjustment of the support rod's length according to the height of adults, children, or adults of different heights, thus adapting to the user's height or usage habits and making it more convenient for the user.
