The latest advancements in the optical world indicate that technicians and scientists are developing auto-focus lenses: new lenses that will focus automatically and will allow the user to see correctly from any distance. As time goes by it becomes normal to loose quality in near vision: this is what is known as presbyopia or tired eyesight. From the age of 40 onwards our eyes gradually lose their capacity to focus near objects correctly, making it necessary to wear eyeglasses to correct presbyopia. Today, an Israeli enterprise called “DeepOptics” is developing modern lenses called “ Omnifocal lenses”. Theese, promise an important revolution in the industry of auto-focus in real time depending on the object seen by the user. How do auto-focus lenses work? These lenses incorporate sensors located close to the bridge of the frame and they can detect where the user’s pupils are looking to. This way they can determine, taking into account the changes of A micro- computer located in the temples receives the signals from the sensors and calculates, with high accuracy, the distance where the object that the user is trying to see is located. Just in a matter of milliseconds this computer sends a signal to the lenses to be adjusted. The lenses include a layer of liquid crystal. This layer is the one which changes its shape depending on the signal transmitted by the computer. Therefore the lenses are prepared by default to see far objects. When the user looks to near object the syste...

Autofocusreaders

Multi Level Readers (also referred to as 3 Level) lenses are designed with a combination of 3 different diopters in one lens. This allows close-up viewing (like reading a book), middle-distance work (like checking out a website on a computer), or distance viewing (like driving) without needing to change your glasses. They are purchased based on the strength needed for reading and feature 2 additional magnifications at .50 less. So, a +2.00 lens will also have +2.00 at the bottom for reading, +1.50 in the center for arm length viewing and +1.00 at the top for distance. Auto Focus Readers feature our Patented technology and contains 275 diopters in one lens…+0.00 to +2.75! The center of the lens is +2.75 and the diopter decreases by 1 degree in 360o out…decreasing to +0.00 on the right and left edge and +.60 on the top and bottom edge. You simply put a pair on and your eyes with find the appropriate strength for your vision needs.

These "Smart Glasses" Adjust To Your Vision Automatically

By age 45, most of us will need glasses at least for reading. That’s because our eyes’ ability to accommodate—to change focus to see objects at different distances—degrades with age. In young eyes, the eyeball’s crystalline lens changes shape easily, allowing this accommodation. But as we get older, this lens stiffens. Objects in close range suddenly look blurry. Hence the “readers” most middle-aged adults begin wearing on a chain or tucking in a handbag, or the bifocals worn by those who already had vision problems. But the days of popping reading glasses on and off or constantly shifting your gaze through bifocals may be numbered. Researchers at the University of Utah have developed “smart glasses” with liquid lenses that can automatically adjust their focus. “The major advantage of these smart eyeglasses is that once a person puts them on, the objects in front of the person always show clear, no matter at what distance the object is,” says Carlos Mastrangelo, the electrical and computer engineering professor who led the research along with doctoral student Nazmul Hasan. Regular prescription glasses, Mastrangelo explains, don’t fix the eyes’ accommodation problems. They simply shift the range of what’s in focus rather than expanding it. So if you put on a pair of reading glasses, the once-blurry page a foot from your eyes will be clear, but objects on the other side of the room will suddenly be blurry. The reverse is true of people who need glasses only for seeing far di...
