Glasses or contact lenses can improve nearsightedness, farsightedness, astigmatism, old light eye problems, but other eye diseases, many have through medical or surgical treatment, with age, the "age-related macular degeneration," is one of them. However, scientists are developing a liquid crystal glasses with contact lenses and ways to improve age-related macular degeneration caused by the deterioration of eyesight, but this method is more beautiful without conspicuous patient's social life will not be affected.
Telescope lens concept
University of California, San Diego professor Joseph Ford ─ Switzerland, the United States led a team developed a thin telescope with the concept of contact lenses in the normal image and switch between the enlarged image. They stick together tightly mirror layers, their thickness above the lens in millimeters (mm) level, the normal view showing the central portion, the peripheral annular part is 2.8 times enlarged view.
To be able to properly switch between perspective and expand their horizons, they designed a liquid crystal glasses, the principle is used from watching 3D TV, 3D glasses.LCD glasses can be set to change the light the way forward, when the light source from different regions across the contact lenses, they can cause vision without magnification effect.
In this version of the picture to open, the left two small images are a front view of this lens with rear view, is the central figure on the right side of the normal field of vision obscured the way, there is no right under the figure masked look.
Program co-investigator Eric Tremblay said the ease of use and does not raise eyebrows, is widely accepted visual aids focus, the general age-related macular degeneration patients to help see things visual aids, is to be transferred to other light no lesion location, so patients can read, recognize people or take care of their daily life, but the drawback is the limited field of view, because some of these devices based on social life and installed in the glasses, and some way must be surgically implanted in the eye . So they developed contact lenses with the advantages of convenience and hidden, you can replace other bulky appliances look good or have surgery, would be a "very attractive option."
