Smart overview of the Invention
A contact lens designed for eye wear consists of a hydrogel material that is biocompatible and allows for the integration of electronic components. These electronic components, which can include sensors, batteries, and microfluidic channels, are fully encapsulated within the lens, ensuring safety and comfort for the user. The lens is intended for various applications such as vision correction, health monitoring, and drug delivery.
Material Composition
The hydrogel used in the contact lens can be made from various materials including polyvinyl alcohol and silicone, among others. These materials are selected for their properties that promote comfort and compatibility with the human eye. The electronic components integrated into the lens may also include bio-compatible materials like carbon nanotubes, ensuring that they do not pose any risk to the user.
Thickness and Reusability
The contact lens is designed to maintain a thickness ranging from 0.05 mm to 0.5 mm, with a focus on achieving a balance between functionality and user comfort. Additionally, the lens can be reusable, which adds to its practicality and sustainability in everyday use.
Manufacturing Process
A method for producing these advanced contact lenses involves heating a solvent, combining it with hydrogel precursors, and placing this mixture into molds that contain the electronic components. This process allows for multiple lenses to be created simultaneously while ensuring that the electronics remain fully encapsulated within the hydrogel.
Drug Delivery Capabilities
In some embodiments, the contact lens can be impregnated with pharmaceuticals for targeted drug delivery. This feature enables the lens to administer medications at specific intervals or as needed, enhancing its functionality beyond traditional uses. Overall, these innovations present a significant advancement in contact lens technology with promising applications in health care and daily life.
