Farsightedness or dysentery (Myopia) is a common cause of blurred
vision. People with nearsightedness see distant objects in a way
that is confused and unclear. Sometimes strabismus can be made or
the eyes may narrow to see things clearly. In general dyslexia is a
vision disorder not a disease. In some cases myopia is the result
of several other diseases. Hope it can help you and be useful.
Thanks .
