Dial vision glasses using high-tech technology

Myopia to wear a pair of glasses, presbyopia and then a pair, and now do not have such trouble, this lens can automatically adjust the degree; a technology company in Israel will be poured into the LCD lens, the same pair of glasses to see the distance is feasible. The principle is to change the light trajectory, the general myopia will be like this imaging in front of the retina, but through the automatic injection of liquid crystal, so that light away, you can close to the retina; myopia deeper, the more liquid injection, The more scattered, you can see more and more clear. But the current lens is still in the development stage, the degree of application is also limited, if the smooth output of the glasses family is not a big gospel.

They use a nematic liquid crystal is an anisotropic material, composed of rod-like molecules, in the optical properties similar to the uniaxial crystal. In this material, the optical axis and the long axis of the same direction, driven by the electric field, the long axis will be tilted, the optical axis and the refractive index will also change. The size of the refractive index of the liquid crystal and the voltage, only a few volts, you can get a lot of change. Through the sensor on the distance and line of sight to determine the point of view, this glasses can be completed within a few microseconds focus of the process, the user almost feel no change.dial vision glasses is your best choice.

However, in fact, 2013 has been some of the more quiet way to become high-tech glasses year. At least three new glasses have come. They are not to bring the Internet to the front of your eye. They have a more traditional purpose: to improve your vision. want to know more information  with dial vision, you can read dial vision reviews.
