Abstract
Visual acuity tester, which is characterized by being a sheet of appropriate material to ensure a certain rigidity, such as cardboard, adopting a shape similar to that of glasses, with two widening corresponding to the two eyes, separated by a notch for mounting on the bridge of the nose and with a lateral extension as a handle, it offers in the center of the two widening corresponding to the eyes and in a centered position, a plurality of small through holes, conveniently grouped in a small area , which will be placed in front of the eyes, when looking to the front, and through which the signs or letters of a "test" can be seen or read, whose vision compared with that obtained without the tester, will determine whether or not they exist defects in vision.
