望远隐形眼镜作文7400字
Lights， mirrors， action！ Scientists are developing smart contact lenses embeddeys Tremblay. A strategic wink will enable users to keep an eye on their periphery， such as cars approaching them as they cross a street， whilst also being able to zoom in and recognize the faces of those around them.
The team developed their technology on scleral lenses， which have an increased thickness and diameter， making them commonly used for more special purpose eye care. “They provide a lot more area to work with，”says Tremblay. The challenge these lenses bring with them， however， is comfort， as they impede the amount of oxygen reaching the eye.
The most recent prototype， unveiled by the team in February， overcame this challenge by introducing air channels to aid the flow of oxygen to the eye. But the team hopes to improve this further still by instead developing a contact lens solution saturated with oxygen， which can be stored and slowly released into the eye. “We will build reservoirs into the back of the lens，” says Tremblay…
The lenses have only been trialled on a handful of humans to test for comfort， with the majority of research to date performed in the lab using a model chemical eye. But more human trials are in the cards， with the eventual goal of daily wearable contacts to aid the visually impaired.
“We want it to move in the direction of a real world vision aid，” says Tremblay.
Getting Smarter
These are not the first smart contact lenses. Other prototypes have been developed to monitor， as well as improve， health in both the eye and across the body.
