Each eyeglass holder knows the discomfort caused by the eye drops commonly used by oculists. To prevent the pupil from narrowing when studying the fundus, when a bright flashlight shines on it, special drops are added to the eye to dilate the pupil. Not only that, from these drops there is a sharpness in the eyes, so then for several hours the outside world looks blurry and, most importantly, it is impossible to work. However, the fundus is investigated not only in people with low vision, so many people have experienced the effects of such eye drops. But it seems that there is a very real prospect of replacing nasty eye drops with a painless study with a video camera, at least as reported by a group of scientists from the University of Illinois and Harvard Medical School. The new development is equipped with a microcomputer, an infrared video camera, a liquid crystal screen and two LEDs, infrared and white. In such a compact video camera (still experimental), the retina will be illuminated not with ordinary, but with infrared light, to which the pupil does not respond, and therefore does not narrow. Photographing is carried out with the help of an instant flash of light, so that the pupil does not even have time to react. Cameras working on this principle are already available, but they have two main drawbacks: large size and high price (not one thousand dollars). The new camcorder is so compact that it fits in your pocket, and its cost is only $ 185.
