My stronger right eye sees sharper (close and far) than my left eye when not wearing glasses. Without glasses it's now seeing more blurry than my weaker, left eye.It's not a major problem and with both eyes open I am functioning just fine.It may have even been this way for over a year.
  
  I don't usually conduct self tests so I don't know when this started. I go for regular check ups each year.My stronger eye usually has been consistently stronger with and without corrective lenses, so it's strange that this is now happening.
  
  Could this be a mild astigmatism?
