I have blurred, sort of double vision in the distance and up close.
Astigmatism.If
you have astigmatism objects will be blurry and sort of double both
far and or near depending on whether you have nearsighted or farsighted
astigmatism.
Astigmatism
is a condition which occurs when the cornea has more than one curvature
(like a football as opposed to a basketball). These multiple curvatures
bend light differently and blurred vision is the result. Normal and
purely nearsighted (Myopic) or purely farsighted (Hyperopic) eyes have
one focal point. There is no such thing a pure astigmatism (where there
is no nearsightedness or farsightedness). With astigmatism, your eyes
have two different focal points. For nearsighted eyes with astigmatism,
both focal points are either in front of the retina or one is focused
on the retina and one in front of the retina. For farsighted eyes with
astigmatism, both focal points are focused behind the retina or one
is on the retina and one behind the retina. Although the word astigmatism
to a layman sounds somewhat more serious (stigmata) than nearsightedness
(Myopia) or farsightedness (Hyperopia), in reality most eyes have some
degree of astigmatism. Laser vision surgery is quite accurate at correcting
astigmatism of up to 4 or 5 Diopters in combination with the correction
of myopia or hyperopia.
