In a movie called Mission Impossible, Tom Cruise used a series of high-tech ray ban which is able to shoot, transmit images and display confidential information. Today, the analogous high-tech glasses will bring the Gospel to hundreds of millions of visually impaired people. The liquid varifocal glass developed by American scientists can change its focus only by adjusting the button on the frame to obtain a better vision than a normal person. Scientists have predicted that this technology will open the door to development of intelligent glasses. This latest technology was invented by the University of Arizona, USA . Now it is send to the state Academy of Sciences to identify the invention.

The biggest difference between liquid crystal glasses and ordinary glasses is lens. The lenses of myopia lens on the market currently or hyperopia mirror are mostly solid glass and resin, which means that they will have only 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 ray ban sunglasses . These crystals are exactly the same as the crystals used in LCD computer monitors. Through the crystal transparency and focusing ability by changing the strength of current flowing passed through the liquid crystal, so the crystal molecules can be rearranged.

Inventors said that the liquid crystal lens is a concentric structure in the identification paper. 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.

During the experiment, models wearing such glass can not see clearly the pictures 30 centimeters in front of them. The liquid glass makes changes in its focus by adjusting the button on the frame. In the end, the models can see pictures clearly. 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 glasses that remedy visual impairment. By adjusting the current strength, the liquid crystal lens can have a variety of different focal length effects. This means it is able to freely transfer between nearsighted glass and farsighted glass. 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, glasses made by this technology will be particularly suitable for the drivers in the future to increase the driving safety. New products will be absolutely no need to adjust manually and become a real smart ray ban shop if we combine this technology with automatic control the strength of current technology.

It is human to love beauty and women love more than others. Mrs. Brown is 46 now. She is very successful in her business and owns whatever she wants. still have a pretty young face at the age of 45. She very concerns about her beauty,
