I had my vision checked two days ago and the optometrist told me my pupillary distance is 64. I went to an optician to try on some glasses today and he said my pupillary distance is 63. My current SRx prescription is -6.25 for both eyes, with a -0.25 cylinder and 165 axis in the left eye. \r\n\r\nI would like to know if a 1 mm difference in pupillary distance for a person with a stronger-than-average prescription will affect the vision when wearing glasses. \r\n\r\nThanks for any input!
