Hello , Arthur . What seems to be the problem ?   Hey doc . Well , I think I might need glasses . I ’ m getting headaches , and I really struggle to see things that are far away . But I have always had 20/20 vision .   Sounds like you may be far-sighted . OK , then cover your left eye and read the chart in front of you .   Mmm .. . X , E , R , 3 , a question mark , and I can ’ t quite make out the other symbol but I think it ’ s the peace sign .   Wow , Arthur ! You ’ re as blind as a bat !   Yeah , I know , my vision is really blurry at times .
