Although progressive glasses, which are suitable for people with diopters for distance and near, have made life easier for visually impaired people, many people find it difficult to get used to them. Well, they might not even have to, because in a few years we'll have glasses with automatic focus.
Glasses with automatic focus have developed on University of Utah in the USA, more precisely a professor Carlos Mastrangelo and Ph.D Nazmul Hasan. Their specialty is that they focus what the human eye is looking at. Similar to a digital camera. They have liquid lenses to thank and infrared sensor, which recalculates the distance between the glasses and the object (this is supposed to happen in 14 milliseconds). Lens curvature changes the focal length and thus sharpness. This is the same process used by the eye itself.

An example of adaptive focus has already appeared some time ago (Adlens), which takes place automatically. Using autofocus glasses is simple. Before use, the user must v dedicated application enter the parameters obtained at ophthalmologist, which it delivers to the glasses using a wireless connection Bluetooth. If you change diopter, so you don't have to change your glasses, you only have to enter new data. The project is currently in the prototype stage and the glasses that will grow out of it will be much more attractive in appearance than in concept. They will be manufactured by the company Sharpeyes, and the battery should provide 24 hours of autonomy. Yes, even prescription glasses will need to be charged one day, just like a smartphone.
