Smart Contact Lenses Developed at the University of Washington

Posted on September 10, 2016 by

University of Washington scientists have developed a way to link your smartphones to your contact lenses using a new technology called the "interscatter communication.” Using this technology, medical aid such as contact lenses and brain implants can send signals to smartphones. The "interscatter communication" works by converting Bluetooth signals into Wi-Fi signals. (Elaborate more here on the technology.) This technology will create Wi-Fi by using Bluetooth transmissions from nearby mobi...

Amazing Water Drop Lenses

Posted on September 8, 2015 by

A new discovery has led to the creation of liquid optical lenses. Bruno Berge, physicist and inventor, has created liquid optical lens by a process known as electro-wetting. In this process, a water drop is deposited on a metal substrate and covered by a thin insulating layer. When a voltage is applied to the metal, it modifies the angle of the liquid drop. The liquid lens is comprised of two liquids, water and oil; one is a conductor while the other is an insulator. A variation in the ...

Contact Lenses Deliver Medicine to Treat Eyes

Posted on September 5, 2015 by

Scientists at Harvard Medical School have developed soft contact lenses which can ‘dispense' prescription drugs over a period of weeks to the exact spot they are needed. Eye drops are used to dispense most eye medications but they are inefficient in several ways. Only about 1 to 7 percent of eye drop medications are absorbed into the eye because most of it drips out; drugs applied to the eyes in this manner may be washed out after only thirty minutes or so. To add, patients find eye drops cum...
