Tom Cruise used a series of high-tech New Era Hats with camera, transmitting the image and displaying confidential informations in the movie "Mission Impossible". Today, the analogous high-tech glasses will bring the Gospel to hundreds of millions of visually impaired people. U.S. scientists have developed a kind of liquid crystal zooming spectacles, you need simply adjust the knob on the to change the focal length to obtain a better vision than normal people. The scientists predict that the technology will open the door to develop intelligent glass. This latest technology was invented by the University of Arizona in USA and it is given to the state Academy of Sciences to identify the invention.
The biggest difference between liquid crystal glasses and ordinary glasses is lens. Currently whether the shortsighted glass or hyperopia glass on the market, their lenses are mostly solid glass and resin, which means they only have a fixed focal length. If the visual acuity is getting better or worse, the user would have to buy new lens. However, the lens of liquid glass consists of crystal liquid wrapped by 2 pieces of thin DC Shoes Hats. These crystals are exactly the same as the crystals used in LCD computer monitors. By changing the strength of current flowing through the liquid crystal, the crystal molecules can rearrange, thereby changing the crystal transparency and focusing ability.
Inventors said in the identification of the paper, the liquid crystal lens is a concentric structure. Liquid crystal inside the lens will occur contraction or expansion deformation in less than one second when the weak electric current pass through the lens. Thus changing the thickness of the various locations of the crystal layer, thereby changing the lens focal length.
In the trial, the model can not see the image of 30 cm away by wearing such glasses. The model can see it clearly at last by adjusting the knob on the , so that the focal length of liquid crystal glasses changed. In the tests among ordinary people, such glasses have also achieved good results.
Scientists predict that one day in the future, this technology may replace all visual impairment glasses. By adjusting the current strength, the liquid crystal of the lens can transform a variety of different focal length effects. This means that it can freely switch between myopia glasses and hyperopia glasses. When the electricity of the lens closed, the liquid crystal then format a uniform thickness, it will be a plain mirror.
Inventor believes that this technology will at least replace the current widespread use of bifocal glasses. In addition, the glasses using such technology are particularly appropriate for drivers, increasing the safety of driving. New products will be aboslutely no need to adjust manually and become a real smart monster energy hats if we combine this technology with automatic control the strength of current technology.
