The dear doctor, I some times measured distance centre to centre an eye (for glasses or spots), and turned out disorder from 62 up to 66 mm. Thus complex or difficult apparatus, Japanese and so on, in solid opticians and out-patient departments were used. How similar can be? Whether influences this strain from job behind a computer in the extremity or end of the working day? Perhaps, it is necessary to accept any weakening or relaxing drops before measurement? Where it is possible to measure distance PRECISELY?

62 it for blizi
66 for a distance.
At a view on close subjects eye axes converge, afar - on the contrary. As a rule the difference makes 3 4 mm.
