In a reachâgrasp task for targets within the binocular visual field, subjects switched between left and right eye dominance depending on horizontal gaze angle. On average, ocular dominance switched at gaze angles of only 15.5Â° off center.
The second line is 20/50. Best corrected acuity in the range between 20/50 and 20/100 is considered disabling in occupations which require work with numbers or extensive reading. The bottom three lines represent 20/30, 20/20 and 20/10. These are considered to be normal vision with the 20/20 line being the traditional normal vision line. It is generally felt that the maximum visual acuity of the eye is around 20/15 or 20/16. This means that if the customer is able to read the bottom line, he/she is probably a good guesser.
