acuity of 0.1 is sufficient for a person to be able to orientate themselves outdoors. However, a visual acuity of 0.8 is required for reading travel timetables. Other minimum values include: 0.4 for watching [...] watching television, 0.5 for reading the newspaper and 0.7 for reading a telephone directory. Is the ability of the eye to read solely dependent on visual acuity? No. In order to be able to read we require [...] reciprocal value of the focal length of a lens measured in metres: a power of +5 dpt therefore has a reciprocal length of 1/5 metres or 20 centimetres. What is long-sightedness? In the case of long-sightedness
