What are Bionic Contact Lenses?


Bionic contact lenses provide a wide array of applications in the modern world, they could assist the visually impaired and aid the video gaming industry. A contact lens is coupled with bionic technology to form a bionic contact lens. This technology comprises of functional electronic circuits and infrared light to create a virtual display environment. These lenses are powered by wireless medium, they have to be bio compatible. They should be integrally designed to minimize radio frequency radiation which could damage the user’s eye.


What Are They Made of?

Bionic contact lenses comprise of hundreds of LEDs which form images in front of the eye, they include words, charts and photographs. They can be optimized to play video games or programmed create a virtual world. They are optimized using integrated control circuits, communication circuits and miniature antennas into the lens using custom built optoelectronic components.
Most bionic contact lenses comprise of a solar cell module which provides uninterrupted power supply to the circuit. A biosensor module is used to store programmed information, followed by a display control unit and radio and power conversion unit. A semi transparent display is attached to the micro lens enabling the user to view the virtual and real world.




How Are They Manufactured?

Bionic contact lenses are assembled, they are linked to an antenna which is used to send and receive signals. They are also used to transmit power to the lens for it to function. An integrated circuit has a thickness of a few nanometers, they are used to harvest power and control LED.
Bionic contacts are assembled using a micro-fabrication technique which powers the electronic circuits. Capillary forces are used to position rest of the components in their respective location.






Applications of Bionic Contacts

Bionic contacts can be synced with your smart phone to help you view emails, text messages, browse the web, watch videos and access social media. They can be used to monitor cholesterol, sodium, and potassium levels in the body. Some contacts are equipped with a wireless data transmitter to send information. They can be updated according to the user’s requirement. They can be used to improve bio engineering and micro mechanics, they are used in the medical field to aid the visually impaired and treat glaucoma. Bionic lenses can be implanted in patients to restore their vision.




How are they worn?

Bionic contact lenses are used to optimize one’s vision they can act as camera lenses and can allow you to zoom in to focus a particular object. They can also be used to increase or decrease the field of vision. Bionic contact lenses need to be implanted into the eye, the user must undergo an 8-minute surgery. The lens is folded and placed in a syringe filled with saline solution and placed on the eye.




Disadvantages of bionic contact lenses

·         The device can work only if it is located close to the wireless battery.
·         It may result in eye damage if it is worn for a long time.
·         Bionic contacts are still under final stages of researching and there is a lot of room for improvement.
·         If not properly tuned they may cause permanent damage to the eye due to high-frequency radiation.
