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 .
