The back sight of a revolver is held further from the eye, as compared with a rifle back sight, and the object to be hit is under fifty yards’ distance. The eyes best suited for pistol shooting therefore are those of moderately long sight, the normal eye in fact.
A near-sighted man, without glasses, has difficulty in seeing the back sight although the range, twenty to fifty yards, would suit his eyes better than rifle shooting at long ranges of eight hundred and one thousand yards.
If a near-sighted man wears glasses the difficulty of seeing equally well at varying distances comes in.
Men who have worn glasses all their lives cannot be made to realize that they cannot adjust their focus.
They, unfortunately, have never experienced the blessing of being able to see a thing close and at a distance with equal distinctness.
Most of them can read without glasses, in fact they take off their glasses if they want to examine anything minutely which they hold in their hands.
For seeing anything further off they wear glasses (but glasses are only a compromise). The glasses are made to enable them to see objects clearly across the street, or to see a motor car before it runs them down.
Anything further is more or less blurred, the further it is the more blurred it looks.
If their glasses were correct for one thousand yards they would butt their heads into everything at fifteen yards off.
It is always best when driving to treat any one wearing glasses very carefully, to remember he can only see in front of him; sideways of his direct vision he may be as blind as a bat or a horse with blinkers on.
