A booth preferred visual acuity test, a booth being operative to quantify visual acuity of a patient, irrespective of the verbal information about the patient (pc), wherein said booth preferred visual acuity test uses Teller cards for the patient, the booth preferred visual acuity test comprising:

• an isolated environment (AS) within a modular structure (20) for the patient (pc) to perform the preferred visual acuity test through reading of Teller cards accommodated within a visualization area (21a), wherein the cards are laid out in a central portion of a sliding movable wall (21) and wherein the sliding wall has wheels (rd) on rails (30, 31) are installed on the ground (22) and ceiling (25), the modular structure (20) presenting a white and opaque tone, as well as its own lighting (II), controlled and fit according to the test, wherein in front of the movable wall (21) and coplanar to the rear wall (24) of the booth (100) there is installed a seat (28) for accommodation of the patient (pc) and an optional companion;
• the movable wall sliding (21) being operative to adjust distance (dl) between the patient (pc) and the visualization area (21a) of cards (CI), wherein the distance varies between a minimum distance of 38 centimeters and maximum distance of 84, varying in accordance with the features of the patient (pc) to optimize accuracy.
