New Technology Makes Artificial 3D Eyeballs
It will never be easy. People will encounter many accidents during their lifetime. Each year seven million people in the world become blind. Our eyes account for around 80% of all our information about the outside world. These statistics show the importance and value of the eyes. A damaged eye could cause disruption to our lives and directly impact our ability to live a normal life. China’s population is 1.4 billion. A large number of blind people means there is more than 10,000,000. China is ranked among the most prolific organ donors in the world every year. However, demand continues to exceed supply. A recent report by Hong Kong University of Science and Technology has proven that it’s no myth that millions of people who are blind will finally see light.
Working principle of the Artificial 3D Eyeball
A study in Nature published by scientists at Hong Kong University of Science and Technology recently revealed the creation of the world’s most advanced 3D artificial eyeball. Designers claim that the 3D artificial eyes use tiny sensors to emulate the light-sensitive cell of an ordinary human eye and USES nanoscale aluminum, tungsten, to make a hemispherical structure of the human retina where the sensor is located. It is approximately the same size as a normal human eye, and can be used to produce high-resolution images. An artificial eye collects information using many sensors. The information is then converted into electrical signals. This is done to imitate human retina in aluminum or tungsten. All frequencies in the visible spectrum of light are sensitive to light.
Three parts make up the human eye: The cornea and the sclera; the iris, choroid and the retina. To create images, human eye imaging uses the eye to convert light stimuli from the outside world into nerve impulses. Light from the outside comes in to show the object to our retina. We then get a signal from the brain and see what it is. Current technologies have the potential to mimic the effect of eye imagery thanks to light sensitive devices and materials. There are some challenges to overcome before this technology works as well as the human eyes. One example is that the human eye can adjust to light levels. Additionally, when the eye is looking at an object stationary, it may fidget to preserve its sense of sensitivity. This creates the illusion that the image “moves”. The illusion of motion may disappear in 3D-augmented eyes. Current clinical and animal studies are being conducted. They are anticipated to be available within five years. This will bring hope to at least five million people.
The Applications Prospect for This Technology
The artificial eye can eliminate human blind spots and has higher sensitivity. The world’s first 3D artificial eyeball has also been created. The technology is not only used to improve vision but could also be used to create other optical sensor devices. While artificial eyes were developed, it is not yet possible to translate optical information into brain waves. The technology has still much to go before being implemented in practice. It is important to take precautions for their eyes.
