Glycerin-filled lenses for glasses autofocus

Many "specticians" will have this experience, and if they want to switch between seeing near and far, they may need to change their glasses. As a result, there are many ways to deal with it, such as multifocal lenses and bifocal lenses, to help achieve the primary goal of seeing far and near with a pair of glasses. There are also zoom glasses like the Adlens, where you can adjust the focus at any time, but this requires a manual touch and a separate operation for each eye. Boots POF13502 Unisex Spectacle Frames BK Black's team of scientists led by Professor Carlos Masrangello of the University of Utah in the United States have gone a step further by recently developing glasses that automatically adjust the focus to what your gaze is looking at, with a "liquid lens" that changes shape. Each spectacle lens consists of two layers of transparent rubber film, one in front and one in the back, sandwiched between a clear and transparent layer of viscous glycerin. The glasses are equipped with three mechanical actuators that can push the back layer of film back and forth to press out or suck in glycerin, changing the curvature of the lens and thus changing the focal length of the glasses. The adjustment instructions received by the actuator come from an automated device that determines what the user's eyes are looking at. An electronic rangefinder on the eyeglass holder uses infrared pulses to determine the distance of the object being viewed in real time. When this distance changes to a certain level, the system informs the actuator to adjust the lens. According to the developers, the process will be completed in 14 milliseconds, which is enough to provide a smooth user experience.

After that, as long as the optical aging does not change, there is no need to readjust, and everything is handled automatically by the glasses. Their results were published in Optics Letters. According to Mastronello, commercially available rechargeable batteries can power the glasses for 24 hours. The prototype in the photo still looks a little bloated, and the final version of the electronic focus glasses will be much lighter. The technology is currently being developed at Sharpeyes, a spin-off company at the University of Utah, and is expected to be commercialized within 3 years.
