Talk to Ent Specialist on Very Minor Eye Blurriness

I was having weird headaches for 2 days so I got my Eye Vision and pressure checked. Alhamdolillah both came out normal 6/6 . During the Vision test when I was reading the alphabets with my right eye opened I noticed that the LAST LINE OF ALPHABETS ON THE BOARD were a little blur but still I could Easily read them . Do u suggest any Eye drops for that minor blurriness or is it normal??
