Bionic contact lenses are being developed that could provide a virtual display for assisting the visually impaired or for use in video games. Researchers created a flexible, biologically safe contact lens using nanotechnology with the goal of creating personal displays. The lens would have electronic circuits and infrared lights to create a virtual display superimposed on the real world. However, the current prototype lens only has a single pixel display and lacks a good power source. Potential applications include using virtual screens for internet, gaming, or monitoring medical conditions, but further development is still needed and potential toxicity risks require further study.

Microscopes allow scientists to see small objects that are too small for the naked eye. There are several key developments in microscope history:
1) The first microscopes in the 2nd century BC used water to magnify objects.
2) Compound microscopes with multiple lenses were developed in the late 16th century, allowing greater magnification.
3) In the 17th century, microscopes became more advanced, with Hooke documenting observations and Leeuwenhoek achieving even higher magnification.
4) Modern microscopes have objective lenses of different powers, eyepieces, stages to hold slides, and other components to provide bright, clear views of microscopic subjects.Microscope

A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is. 5 - 12+ Biology, Engineering.Luminescence

Photonic crystals are periodic optical nanostructures that affect the propagation of light. They contain regions of high and low dielectric constants arranged in a repeating pattern, allowing certain wavelengths of light to pass through while others are forbidden from propagating, known as a photonic band gap. Photonic crystals have applications in lasers, optical fibers, biosensing and more. They can be fabricated through methods like layer deposition, photolithography or drilling holes to achieve one, two or three-dimensional periodicity.Optical telescope

Telescopes use lenses or mirrors to make distant objects appear larger and closer. Refracting telescopes use lenses to bend and focus light, while reflecting telescopes use curved mirrors. Catadioptric telescopes combine mirrors and lenses. Telescopes are used to observe objects that are too far away to see clearly with the naked eye, without needing to physically get closer. The magnification of a telescope depends on the focal lengths of its objective lens and eyepiece. Larger aperture telescopes can capture more light but have limitations like chromatic aberration.Superconductivity

Superconductivity was discovered in 1911 by Heike Kamerlingh Onnes, who observed the electrical resistance of mercury abruptly disappeared at 4.2 K. Superconductivity occurs in certain materials at very low temperatures and is characterized by zero electrical resistance and perfect diamagnetism. The BCS theory from 1957 explained superconductivity as a superfluid of electron pairs called Cooper pairs that interact through phonon exchange. Superconductors exhibit properties like the Meissner effect, Josephson effect, and isotope effect. They are classified by critical temperature, magnetic response, and materials. Superconductors find applications in areas like magnetically levitated transportation, MRI machines, and power grid technologies.Microscopy

According to a survey made by World Health Organization
(WHO) in 2023, over 2.2 billion of people are affected by visual
disabilities, it was with a challenge that this project came into
being. It aims at restoring vision to the blind. High-tech advancements in microelectronics, Optoelectronic,
computer science and biomedical engineering are working
together to realize a device for the electrical stimulation of
An artificial eye, also known as a prosthetic eye or bionic eye, is
a custom-made device designed to replace a natural eye that
has been lost or removed due to injury or disease.
[1]
Advancements in technology have led to the development of
functional prosthetic eyes embedded with microelectronics and
sensors, aiming to restore partial vision to individuals with
severe visual impairments or blindness.
Microelectronics and Sensors: Capture visual from the
surrounding. Image Processing: Convert visual data into electrical signals and
enhance quality. Stimulation of Remaining Healthy Cells: Electrodes transmit
electrical signals to the retina or optic nerve. Creation of Visual Perceptions: Stimulated cells generate neural
activity interpreted as visual perceptions by the brain. Feedback Mechanisms: Adjust stimulation levels based on
environmental changes or user preferences.
A prosthetic eye, or ocular prosthesis, is an artificial eye implant that mimics the appearance of a natural human eye. Ocular prosthetics enhance the comfort and appearance of people who have lost an eye to severe injury or disease.
Common reasons why people might need a prosthetic eye include:
Eye injury
Glaucoma
Eye infection
Ocular cancer
People have been using prosthetic eyes throughout history. Long ago, prosthetic eyes were made of glass. Today, theyre made of medical-grade plastic acrylic, which is more durable.
A prosthetic eye isnt a sphere like an eyeball. Its a thin, removable disc that covers an ocular implant placed during eye removal surgery (enucleation). The disc is custom-made to match the existing eye.
What is an Ocularist?
An ocularist is a highly skilled professional who makes and fits ocular prostheses. They customize prosthetic eyes to resemble natural eyes. This includes an iris, pupil, sclera (white of the eye), and even blood vessels.
How Does a Prosthetic Eye Work?
After eye removal surgery, a round, porous implant gets placed in the empty socket. It may be made of coral or synthetic material. The implant gets wrapped in eye tissue and attached to muscles that enable normal eye movement.
The ocular prosthesis attaches to the implant, which is attached to the eye muscles. This allows the prosthesis to move in sync with the natural eye. You can cry, swim, and shower while wearing an ocular prosthesis.
However, an eye prosthesis wont provide vision, and the pupil will not respond to light.
How Much Does a Prosthetic Eye Cost?
The cost of a new prosthetic eye can range from $2,000 to more than $8,000 without health iEmerging Trends

A cyborg is defined as an organism with both artificial and natural systems that work together in a self-regulating manner. Early science fiction popularized the idea before World War II, and the term "cyborg" was coined in 1960. Steve Mann is considered one of the first cyborgs for his early work with wearable webcams. Kevin Warwick is a leading expert in cybernetics who has conducted experiments implanting electrode arrays in his own body to control devices. Cyborg technologies can help prolong human life by assisting failing organs like hearts and kidneys. While benefits are vast, the risks of such advances must also be considered.Living in a World of Nanobioinfotechnology

Nano robots, also known as nanobots, are theoretical microscopic devices that could operate at the nanoscale level. If developed, nanobots may be programmed to perform medical and industrial tasks like targeted drug delivery, disease detection, circuit repair, and environmental cleanup. However, developing reliable navigation, power supply, and biocompatibility for nanobots remains a challenge. Future applications may include disease prevention through continuous health monitoring and multi-functional nanobots capable of simultaneous sensing, drug delivery, and tissue repair. Significant research is still needed to responsibly develop and integrate nanobots with technologies like artificial intelligence.Final aartifical eye seminar report march2016

- 1. BIONIC CONTACT LENS Bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry. Bion means unit of life and ic meaning like, hence it is like life. The device will have the form of conventional contact lens with added bionics technology. The lens will eventually have functional electronic circuits and infrared lights to create a virtual display. Researchers at the University of Washington created a flexible, biologically safe contact lens using nanotechnology in hopes of creating personal displays similar to those used in movies such as Terminator or Bionic Woman. Looking through the bionic contact lens, you would see the display superimposed on the real world. Construction The lenses require organic materials that are biologically safe and also use inorganic material for the electronic circuits. The electronic circuits are built from a layer of metal a few nanometers thick. The light-emitting diodes are one third of a millimeter across. A grey powder is sprinkled onto the lens. Then a technique called micro fabrication or self-assembly is used to shape each tiny component. Capillary forces pull the pieces into their final position. The technology was trialed at the University of Washington in Seattle, and currently theyre safe and feasible, but lacking a good power source and only have a single-pixel display. The device is still best characterized as a prototype. The micro circuitry only is enough to supportone light-emitting diode. Applications Scientist believes that, this could serve as a flexible plastic platform for application such as surfing the internet on virtual screen, immersing gamers in virtual worlds and monitoring patient medical conditions.
- 2. Such virtual displays could be useful to drivers and pilots, who could obtain route, weather, or vehicle status information shown on the windshield of the airplane. Monitoring of human biological conditions - cholesterol level or the presence of viruses and bacteria that transmits the data wirelessly to a computer. Miniature cameras with adaptive lenses could be incorporated which have the ability to zoom in on something far away or to look at something very close - providing, essentially, bionic vision. Potential hazards Complicated Materials used for Construction. Toxicity of Chemicals when used on Larger Scale. The hazard studies that have been done show evidence that nanomaterials have the potential to cause oxidative damage, to punch holes in cell membranes, to kill cells in culture, and to have harmful impacts on populations in ecosystems. .
