Abstract
Przedmiotem zgłoszenia jest urządzenie służące do wyznaczania odległości dobrego widzenia charakteryzujące się tym, że zawiera punktowe źródło światła (201) o średnicy mniejszej od 1 mm, przy czym długości fali światła emitowanego przez punktowe źródło światła zawierają się w przedziale od 436 nm do 495 nm dla światła niebieskiego i od 627 nm do 780 nm dla światła czerwonego.The subject of the application is a device for determining the distance of good vision characterized in that it contains a point light source (201) with a diameter smaller than 1 mm, with the wavelengths of light emitted by the point light source being in the range from 436 nm to 495 nm for blue light and 627 nm to 780 nm for red light.
