Objective:
To explore the advancements in contact lenses (CLs) that extend beyond vision correction, including disease diagnosis, drug delivery, and imaging applications.
Key Findings:
- Smart CLs can diagnose diseases through noninvasive biosensing of biomarkers in tear fluid.
- Innovative drug delivery methods using CLs can improve therapeutic efficacy.
- 3D printing allows for customized CLs tailored to individual needs.
- AR-enabled CLs have potential applications in navigation and low-vision rehabilitation.
- AI integration can enhance diagnostic processes and treatment personalization.
Interpretation:
The future of contact lenses is shifting towards multifunctional devices that not only correct vision but also diagnose diseases, deliver medications, and integrate with advanced technologies like AR and AI.
Limitations:
- Challenges in miniaturizing electronics and ensuring biocompatibility.
- Regulatory hurdles and the need for extensive clinical trials.
- Technical difficulties in integrating complex electronics into soft materials.
Conclusion:
The evolution of contact lenses into smart devices presents significant opportunities for personalized healthcare and improved patient outcomes, but collaboration across disciplines is essential to overcome existing challenges.
