The LCD Alterable Focal Point Glasses Will Open The Door To Intelligentized Spectacls

In a movie called Mission Impossible, Tom Cruise used a series of high-tech bifocal eyeglasses which is able to shoot, transmit images and display confidential information. Now, a similar high-tech glasses will bring good news for millions of visually impaired people. Scientists in U.S. have developed a liquid crystal optical glasses, you can obtain a better vision than normal people by simply adjusting the knob on the frame to change the focal length. Scientists have predicted that this technology will open the door to develop intelligent glasses. The latest technology, invented by Arizona university in the USA, has currently been turned over to the scientific academy of the state for invention identification.

The biggest difference between liquid crystal glasses and ordinary glasses is on the lens. Whether it is a nearsighted glass or a farsighted one on the current market, the lens tends to be a solid glass and pitch, which means they only have fixed focus. 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 bifocal glasses. These crystals are exactly the same as that 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.

In the identification thesis, the crystal in the lens is a concentric structure. When the weak electric current through the lens, the lens inside the liquid crystal will occur contraction or expansion deformation in less than one second. Thus changing the thickness of the various locations of the crystal layer, thereby changing the lens focal length.

In the trial, the model wearing such glasses can not clearly see the picture in front of 30 cm. The liquid glass makes changes in its focus by adjusting the button on the frame. In the end, the models can see pictures clearly. Such glasses have also achieved good results in the tests done by ordinary people.

Scientists predict that one day, the technology will take the place of all other glasses which are made to make up for eyesight deficiency. By adjusting magnitude of current, the crystal in the lens can change the focus from one to another. 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.

The inventor believes that this technology will be at least replace the bifocal glasses that has been currently widespreaded. In addition, glasses manufatured by this technology will particularly be suitable for drivers to increase the driving safety in the future. If combined with the technology of controlling the current automatically and the new products will be absolutely free from manually operation to become the real smart bifocal lens.

Ways for Sunglasses Upkeep

The eyeglasses are took off and wore frequently, it will scratch accidentally, so there are some small details to remind you particularly.

If there are some sweat points on the sunglasses, do not use your nails to pull, which will easily scratch the surface.

Or some people would put them in handbags, but it will be wiser to put them into hard spectacles cases before putting them in handbags, Lest the lens will be fretted away by small matters such as keys, combs, copperplates and so on, or may be tainted by makeups such as lipsticks and so on.

The drivers like putting the sunglasses on the dashboard or the seat when they do not wear them ,which is such a bad habit.

When the reading glasses are not used, it should be wrapped by glasses cloth and put in the glasses box, so as to avoid damage.

The LCD Variable Focal Point Glassess Will Lead The Door To Intelligent Eyeglassess

In the movie "Mission Impossible", Tom Cruise used a series of high-tech prescription sunglasses with image pickup, image transmit and display of confidential information. Today, a similar high-tech glasses will bring the Gospel to millions of visually impaired people. Scientists in U.S. have developed a liquid crystal optical glasses, you can obtain a better vision than normal people by simply adjusting the knob on the frame to change the focal length. Scientists have predicted that this technology will open the door to development of 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 zooming glasses and ordinary glasses lies in 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 vision got better or worse, the user would have to get a new one. However, the lens of liquid glass consists of crystal liquid wrapped by 2 pieces of thin prescription eyeglasses. These crystals are exactly the same as LCD computer monitors on the crystals. 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. 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, the thickness of the crystal layer will be altered so as to change the focus.

In the trial, the model who wears such glasses can not see the picture being 30 cm far away from him. But by adjusting the knob on the frame, the focal length of liquid crystal glasses has changed, he can clearly see the final model image. Such glasses have also achieved good results in the tests done by ordinary people.

Scientists predict that one day, the technology will take the place of all other glasses which are made to make up for eyesight deficiency. By adjusting the current strength, the liquid crystal lens can have a variety of different focal length effects. This means that it can freely switch between myopia glasses and hyperopia glasses. The crystal forms an even thickness which becomes a mat gloss after the current through the lens is shut off.

Inventor believes that this technology will at least replace the current widespread use of bifocal glasses. In addition, glasses manufactured by this technology particularly suitable for the driver to wear in the future to increase the driving safety. 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 prescription glasses.
