Eyesight. You must also have an adequate field of vision and a visual acuity of at least decimal 0.5 (6/12) on the Snellen scale (with glasses or contact lenses, if necessary), using both eyes together or, one eye only if the driver only has sight in one eye.Click to see full answer. Likewise, what is 6 12 on the Snellen scale?If this is the smallest line a person can read, the person’s acuity is “6/12” (“20/40”), meaning that this person needs to approach to a distance of 6 metres (20 ft) to read letters that a person with normal acuity could read at 12 metres (39 ft).Also, what is the normal eyesight range? 20/20 vision is considered “normal” vision, meaning you can read at 20 feet a letter that most human beings should be able to read at 20 feet. Subsequently, question is, how do you read a Snellen chart? Recording Snellen Results Top number equates to the distance (in metres) at which the test chart was presented (usually 6m), Bottom number identifies the position on the chart of the smallest line read by the ‘patient’. Eg; 6/60 means the subject can only see the top letter when viewed at 6m.What is 6 7.5 on the Snellen scale?The minimum acuity standard is 6/7.5 in the better eye and 6/60 in the worse eye. To state that the visual acuity is 6/7.5 the individual must be able to read all characters on the appropriate line on the Snellen chart (i.e. 6/9+3 or 6/6-2 are not acceptable).
