A LENS STERILIZATION AND STORAGE DEVICE
TECHNICAL FIELD
[0001] The present invention relates to optical care. Most particularly, the invention is a lens sterilization and storage device that addresses hygiene, secure storage, and precise sterilization of optical lenses using UV-C technology, magnetic 5 slots, and user controls, ensuring effective disinfection and improved patient safety in eye care settings.
BACKGROUND
[0002] Contact lenses have become an essential part of vision correction for millions of people worldwide. Their convenience and effectiveness have made 10 them an attractive alternative to spectacles, especially for those who prefer a natural look or need a wider field of vision. However, one of the most critical challenges associated with contact lens usage is maintaining hygiene. Proper cleaning, sterilization, and storage of contact lenses are necessary to prevent microbial contamination, which can lead to eye infections, irritation, or even severe 15 conditions such as keratitis.
[0003] Existing lens sterilization and storage systems are often manual and require multiple steps, such as rinsing, disinfecting, and storing lenses in a designated container filled with a special solution. Traditionally, users have relied on contact lens solutions containing disinfecting agents like hydrogen peroxide, saline, or 20 enzymatic cleaners. These solutions work to break down protein deposits and neutralize harmful microorganisms that could accumulate on the lenses during wear. Despite their widespread usage, these methods have inherent limitations.
[0004] The manual nature of the process demands careful adherence to a strict routine, which leaves considerable room for human error. Users may forget to 25 replace the solution, fail to clean their lens case adequately, or not allow the lenses to soak for a sufficient duration, resulting in insufficient sterilization. Such lapses
3
can allow bacteria or fungi to grow on the lenses, posing serious risks to the eyes. Additionally, the incorrect handling of hydrogen peroxide solutions can lead to chemical burns if lenses are not properly neutralized before wearing, leading to discomfort and a decline in user compliance.
[0005] Moreover, conventional lens cases that hold the sterilizing solution do not 5 actively contribute to the cleaning process. Most of them simply serve as passive containers, relying entirely on the effectiveness of the solution. The static design of these cases means there is no mechanism to enhance the cleaning efficiency, such as through agitation or temperature control. This can lead to incomplete disinfection, particularly when biofilms—an adherent layer of microorganisms—10 develop on the surface of the lenses or within the case itself. Biofilm formation is particularly challenging to manage, as it can be highly resistant to disinfectants.
[0006] In addition to these drawbacks, storage systems currently in use lack the ability to ensure consistent sterility over time. Many users do not replace their lens cases frequently enough, leading to the accumulation of microbial contamination 15 within the case, which then poses a risk each time lenses are stored. Studies have shown that lens cases can become a breeding ground for pathogens, contributing to conditions such as Acanthamoeba keratitis, a serious and painful infection that can threaten vision.
[0007] Several attempts have been made to address these issues by introducing 20 ultrasonic cleaning devices, automatic disinfection systems, or lens cases with embedded UV sterilization. While these innovations represent progress, they also come with limitations. Ultrasonic cleaners, for instance, can be bulky and often require separate power sources, making them less convenient for daily use or travel. Automatic disinfection devices can be prohibitively expensive for many users, 25 limiting widespread adoption. UV sterilization systems embedded within lens cases require careful calibration, as excessive UV exposure can degrade lens material and affect the integrity and comfort of the lenses.
4
[0008] Despite these advancements, there remains a need for a more effective, user-friendly, and affordable solution for the sterilization and storage of contact lenses. An ideal system would minimize human error, enhance the disinfection process, ensure ongoing sterility during storage, and be convenient for users to operate on a daily basis. Such a solution would significantly reduce the risk of infections, 5 enhance the comfort and health of contact lens wearers, and potentially increase compliance with recommended hygiene practices.
[0009] While existing systems have made significant strides in improving contact lens hygiene, they still suffer from critical drawbacks, including dependency on user compliance, insufficient sterilization capabilities, biofilm formation, and high 10 costs associated with more advanced solutions.
[0010] Thus, addressing these problems, the proposed lens sterilization and storage device offers an effective solution to the issues of lens misplacement and inadequate sterilization in optical care. It features secure and organized lens placement, reducing the risk of misplacement. To enhance lens hygiene, the device 15 incorporates adjustable intensity for efficient sterilization, adaptable to different lens materials. Specifically, the device ensures energy efficiency and allows for safe monitoring of the sterilization process. This design addresses key concerns in lens care, enhancing safety and user convenience in optical care settings. 20

[0046] Referring Figure 1(a) and Figure 1(b) a lens sterilization and storage device. The lens sterilization and storage device present a sophisticated integration of multiple technologies within a compact and user-friendly structure, designed 5 specifically to meet the diverse needs of lens care and sterilization. The following detailed analysis will explore the various components and configurations that collectively enhance the functionality and effectiveness.
[0047] At the core of the device is a cuboidal housing that forms the primary structure, providing a robust framework for all internal components. The cuboidal 10 shape is not merely aesthetic; it serves a critical purpose by maximizing internal volume while maintaining a compact footprint suitable for both residential and commercial environments. The cuboidal housing is constructed from high-grade materials that offer durability and resistance to environmental factors, ensuring that the device remains functional over time. The top lid is configured to securely cover 15 the cuboidal housing, preventing external contaminants from entering during the sterilization process, while also ensuring ease of access for lens placement and retrieval.
[0048] The lid’s design includes secure fastening mechanisms, which may incorporate latches or magnetic closures to maintain a tight seal during operation. 20 This design is vital for ensuring that UV-C light remains contained within the housing, optimizing the sterilization process while also protecting users from harmful exposure. The overall ergonomic design of the device enhances user experience, allowing for intuitive operation without compromising on safety.
[0049] Integral to the sterilization process are the pair of UV-C lamps, which are 25 strategically positioned within the lid. Their placement is crucial, as it allows for optimal distribution of UV-C light throughout the internal cavity of the housing, ensuring that all surfaces of the lenses are adequately exposed to the sterilizing light. The adjustable intensity feature is a significant innovation, accommodating
12
the unique properties of various lens materials—some may require lower UV intensity to prevent degradation, while others may need higher intensity for effective sterilization.
[0050] The configuration of these lamps is designed to facilitate easy replacement and maintenance, recognizing that UV-C lamps have a finite lifespan and must be 5 replaced periodically to ensure the device operates at peak efficiency. The integration of a control circuit within the housing allows for fine-tuning of the UV output, enabling users to select the appropriate intensity based on the specific lens type in use.To provide secure and organized placement of lenses, the device features a plurality of magnetic slots that are seamlessly integrated into the cuboidal 10 housing. This innovative design element ensures that lenses are held securely in place during the sterilization process, significantly reducing the risk of misplacement or damage. Each magnetic slot is engineered to accommodate lenses of various diameters, offering versatility for users with different lens types.
[0051] Furthermore, the magnetic slots are lined with a non-slip surface that 15 enhances stability during operation. This surface is engineered to grip the lenses firmly, preventing any movement that could lead to uneven exposure to UV light. This configuration is particularly important in maintaining the integrity of the sterilization process, as any shift in lens position could compromise the effectiveness of UV exposure. Another critical component of the lens sterilization 20 and storage device is the temperature control unit, which is designed to maintain an optimal environment for lens sterilization. The thermoelectric cooler integrated into the cuboidal housing is configured to actively monitor and control the internal temperature. This is particularly crucial as excessive heat could lead to heat-induced damage to sensitive lens materials. The temperature control unit operates in 25 conjunction with the UV-C lamps, dynamically adjusting cooling efforts in response to the heat generated during the sterilization cycle. By maintaining a predefined threshold, this mechanism ensures that lenses are safeguarded against thermal degradation while still achieving effective sterilization.
13
[0052] The digital timer is a pivotal feature of the device, allowing users to customize the sterilization duration to meet their specific needs. Configured within the cuboidal housing, this timer offers a user-friendly interface that facilitates easy setting and adjustment of the sterilization duration, with options ranging from 10 seconds to 10 minutes. This flexibility is essential for accommodating the varying 5 sterilization requirements of different lens materials.
[0053] The interface may feature a digital display that provides real-time feedback on the selected duration, remaining time, and completion status of the sterilization process. This information empowers users to engage actively with the device, promoting awareness and adherence to best practices in lens hygiene. To enhance 10 energy efficiency and safety, a magnetic sensor is strategically positioned at the edge of the lid. The magnetic sensor is crucial for detecting the presence of lenses within the device. Upon detection, it activates the UV-C lamps, initiating the sterilization process. Conversely, the magnetic sensor also serves to deactivate the lamps when no lenses are present or when the lid is opened, thereby preventing 15 unnecessary energy consumption and protecting users from UV exposure.
[0054] The integration of this sensor not only optimizes the sterilization cycle but also contributes to the overall sustainability of the device. By minimizing energy waste, the device aligns with contemporary environmental considerations, appealing to the growing demographic of eco-conscious consumers. A noteworthy 20 aspect of the device's configuration is the inclusion of a UV-resistant transparent window situated beneath the lid. This window serves a dual purpose: it facilitates visibility into the cuboidal housing, allowing users to monitor the sterilization process without needing to open the lid, and it provides a safety barrier that protects users from UV exposure. 25
[0055] The transparent material is specifically chosen for its ability to withstand UV radiation, ensuring that it does not degrade over time while also allowing sufficient UV light to penetrate during the sterilization process. This feature enhances user confidence, as they can visually confirm that the sterilization is
14
underway while maintaining a safe operational environment. Finally, the lens sterilization and storage device is equipped with a power supply system that includes a rechargeable battery, enabling portable operation. This feature allows users to utilize the device in various settings, from home environments to professional optical shops, without being tethered to a power outlet. The battery is 5 designed for longevity, ensuring that the device can operate for extended periods between charges.
[0056] The portability of the device is complemented by its lightweight design, making it easy to transport. This configuration addresses the needs of users who may require lens sterilization on the go, such as travelers or individuals who 10 frequently change locations.
[0057] Moreover, the lens sterilization and storage device is a well-engineered invention that effectively combines advanced technology with practical design principles. Its cuboidal housing, innovative UV-C lamp configuration, secure magnetic slots, temperature control mechanisms, user-friendly digital timer, 15 energy-efficient magnetic sensor, UV-resistant transparent window, and portable power supply system collectively create a highly functional and user-centric device. This invention not only addresses the pressing need for effective lens sterilization but also enhances the overall user experience, making it a valuable addition to the field of optical care. 20
[0058] Referring to Figure 2, illustrates a method for sterilizing and storing optical lenses represents a comprehensive and systematic approach that effectively combines advanced technology with practical application. This method ensures not only the cleanliness and safety of optical lenses but also their structural integrity during the sterilization process. The following elaboration outlines the distinct steps 25 involved in this method, providing insight into the underlying mechanisms and considerations that enhance its effectiveness.
[0059] The method begins with placing at least one optical lens into a magnetic slot within the lens sterilization and storage device. The design of these magnetic slots
15
is crucial, as they are engineered to securely hold various types and diameters of lenses. This secure placement minimizes the risk of displacement during operation, which is essential for effective sterilization. The magnetic slots are often lined with a non-slip surface, ensuring stability and preventing any unwanted movement that could lead to uneven UV exposure or potential damage to the lens. This careful 5 consideration of lens placement not only improves the efficacy of the sterilization process but also facilitates user-friendly operation.
[0060] Once the lens is positioned in the magnetic slot, the next step involves detecting its presence using a magnetic sensor. This sensor plays a critical role in the overall efficiency of the method. It is designed to recognize the presence of the 10 lens and send a signal to activate the UV-C lamp, thereby initiating the sterilization process. This automatic detection feature is instrumental in enhancing energy efficiency, as it ensures that the UV-C lamp is activated only when lenses are present, thus preventing unnecessary energy consumption and prolonging the lifespan of the lamp. 15
[0061] Upon detection of the lens, the method automatically activates a UV-C lamp that emits ultraviolet light at an adjustable intensity. This feature is particularly significant, as different lens materials have varying levels of sensitivity to UV exposure. By allowing for intensity adjustments, the method accommodates a broad range of lens types, from delicate prescription lenses to more robust materials used 20 in safety glasses. This adaptability is critical for ensuring thorough sterilization while preserving the integrity of the lens materials.
[0062] The UV-C lamp operates within a specific wavelength range, typically between 200 to 280 nanometers, which is highly effective at destroying pathogens while remaining safe for the lenses themselves. This focus on both effectiveness 25 and safety is a hallmark of the method, ensuring that lenses are sterilized without compromising their structural integrity.
[0063] A key aspect of the method involves setting a sterilization duration using a digital timer integrated into the device. This timer allows users to customize the
16
exposure time of the UV-C lamp, with typical settings ranging from 10 seconds to 10 minutes, depending on the specific lens material and the level of sterilization required. The ability to adjust the duration is essential for accommodating different sterilization needs and ensuring optimal results.
[0064] The digital timer not only enhances user control but also promotes 5 adherence to best practices in lens care. It provides real-time feedback on the sterilization process, allowing users to monitor the remaining time and ensuring that they can effectively manage their lens care routine.
[0065] Simultaneously, the method incorporates a temperature control unit designed to regulate the internal temperature of the device during the sterilization 10 process. This unit is critical for preventing heat-induced damage to the lenses, which can be particularly sensitive to elevated temperatures. By maintaining a stable temperature below a predefined threshold, the method ensures that the lenses are protected from thermal degradation while still achieving effective sterilization.
[0066] The temperature control unit typically employs a thermoelectric cooling 15 mechanism, which is both efficient and reliable. This proactive approach to temperature management highlights the method’s emphasis on preserving lens quality throughout the sterilization process.
[0067] Users are provided with the ability to monitor the sterilization process through a UV-resistant transparent window located in the device. This design 20 feature serves a dual purpose: it allows users to visually confirm that the sterilization is in progress while ensuring safety by preventing UV exposure. The transparent window is crafted from materials specifically selected for their ability to withstand UV radiation, thereby enhancing the device's longevity and user safety.
[0068] By enabling visibility into the sterilization chamber, the window contributes 25 to user confidence in the device's operation, allowing for real-time assessment without the need to open the lid and interrupt the sterilization cycle.
17
[0069] Once the set sterilization duration is completed, the method incorporates an automatic deactivation feature for the UV-C lamp. This not only signifies the completion of the sterilization cycle but also further enhances safety by ensuring that the UV-C light is turned off when not needed. This automated functionality minimizes the risk of user exposure to UV light when retrieving lenses and 5 promotes energy efficiency by conserving power.
[0070] Finally, after the sterilization cycle is complete, the method ensures that the lenses remain securely held in the magnetic slots until they are ready to be removed for use. This feature underscores the device's commitment to safety and usability, as it prevents accidental dislodgment of the lenses during or after the sterilization 10 process. The magnetic slots are designed to hold lenses firmly in place, ensuring that they remain organized and easily accessible for users.
[0071] The method for sterilizing and storing optical lenses is a meticulously crafted process that integrates advanced technology with practical user considerations. Each step, from lens placement to automatic deactivation of the 15 UV-C lamp, is designed to maximize both effectiveness and safety. The combination of secure magnetic slots, adjustable UV-C lamp intensity, customizable sterilization durations, effective temperature control, and real-time monitoring capabilities positions this method as a leading solution in lens care. This method not only addresses the pressing need for effective lens sterilization but also 20 enhances user experience through thoughtful design and functionality. As the demand for hygienic lens care continues to grow, this method offers a comprehensive, user-friendly, and efficient approach to maintaining the cleanliness and integrity of optical lenses.
[0072] While certain present preferred embodiments of the invention have been 25 illustrated and described herein, it is to be understood that the invention is not limited thereto. Clearly, the invention may be otherwise variously embodied, and practiced within the scope of the following claims.
