The Liquid Crystal Variable Focus Glassess Will Open The Door To Intelligentized Glasses

Tom Cruise used a series of high-tech glasses with camera, transmitting the image and displaying confidential informations in the movie “Mission Impossible”. Now, a similar high-tech glasses will bring good news for millions of visually impaired people. U.S. scientists have developed a liquid crystal optical zoom. You can change the focal length to obtain a better than normal vision simply by adjusting the knob on the frame. Scientists predicted that this technology will open the door to develop intelligent glasses. This latest technology is the invention of the University of Arizona USA and it has now been delivered to the state Academy of Science for invention identification.

The biggest difference between liquid crystal glasses and ordinary eyeglass frames is on the 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. And the lens of liquid crystal prescription sunglasses was composed by two ultra-thin glass-coated crystalline liquid. The crystal is exactly the same as those on the computer screen. Through changing the strength of current flowing through the liquid crystal, the crystal molecules can be re-arranged thereby to change the crystal’s transparency and focusing ability.

In the identification thesis, the crystal in the lens is a concentric structure. When the feeble current flows through the lens, the crystal in the lens will shrink or swell in less than one second. Thus, the thickness of the crystal layer will be altered so as to change the focus.

In the trial, the model wearing such glasses can not clearly see the picture in front of 30 cm. The model can see it clearly at last by adjusting the knob on the frame, so that the focal length of liquid crystal glasses changed. Such glasses have also achieved good effect in the test for ordinary people.

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 of the lens can transform a variety of different focal length effects. This means it is able to freely transfer between nearsighted glass and farsighted glass. It is a plain mirror when the current of the lens was closed and the liquid crystal formed a even thickness.

Inventor believes that this technology will at least replace the current widespread use of bifocal glasses. In addition, glasses manufatured by this technology will particularly be suitable for drivers to increase the driving safety in the future. If it is combined with the automatic control technology, it is of no need for new products to manually adjust and become a real intelligent eyeglasses.

The “Murderer”–Sunglasses

Recently my dad had an accident, fortunately it was not serious. My dad has been in hospital for two weeks and today he is discharged form hospital. I came to take him home. On the way home, we talked about something about the accident. I was always thinking how could my dad have a car accident? He drove very carefully and never drinks when driving. My dad said he also didn’t know something was wrong. He just felt very tired, couldn’t concentrate   and without notice his car crushed into the trees beside the road. Fortunately there is no passer-by.

I also don’t where the problem was. As I am driving, the sun rose and I put on the sunglasses in the car to see clearly. After ten minutes I feel not good—I can’t see clearly. So I take them of and put on my own sunglasses. When we arrive home, I begin to check the sunglasses in the car. I found its lenses are damaged. I go to Google immediately. Quickly I know why my dad had an accident—it’s all because of this damaged resin lenses!

It is said that the high temperature can make the resin lenses distort and blur. People who put this kind of glasses for a long time when driving can hardly concentrate and feel tired easily. Especially for the person who is hyperopic o astigmatism. My dad is hyperopic and my dad’s car is always parking outdoors. So the hot sun in the summer must have turned the temperature in car very high. What’s worse, my dad always put this pair of sunglasses in the car because in other occasion he doesn’t need sunglasses.

After understanding the problem, I go to tell dad. Dad says:” I will never leave the sunglasses in the high temperature! Oh, poor this pair of sunglasses, it nearly took my life—it is the murderer! Thanks my son, you’ve done a good job. Oh, I must tell Henry, he also does this like me. God bless him; hope he is not in hospital now.”

This accident now can totally come to the end. Anyway, be careful life is priceless.
