"Tunnel vision" -what causes it?
|Post Reply Topic Search Topic Options|
What facet of scope construction causes the tunnel vision effect that we see in some scopes (such as many Nikons)?
Also, can someone explain what design elements cause some scopes seem to be more sensitive to eye movement than others?
Is it possibly a good thing for accuracy to have a smaller eye box that doesn't allow as much lateral eye movement before the scope "crescents out" on one side ?
I have an old Bushnell 4x that allows almost no eye movement before the image crescents out on one side. Yet other,newer scopes with greater eye relief, seem to allow a great deal of eye movement before the scope's field of view is compromised or it crescents out on one side. Doesn't that bigger eyebox essentially allow for a greater parallax error? Or is this just relevant to objective size (which also affects parallax to some degree).
