Still confused and/or concerned? See a doctor face-to-face. I don't think you can go any further in this forum. LB, O.D. |

| What do you mean "if your distance vision is equally clear, then the powers are correct"? It is very hard for me to judge whether these are correct myself - partially cause Toric lenses are always a bit funky. I guess I am trying to get some confidence that this type of flipping could easily happen. Otherwise I guess the only way to confirm is to get an independent eye exam but I would prefer to not spend the money Josh |

Or could this be correct? spectacle power, then it would appear that the contact sphere power is incorrect. BUT: If your distance vision is equally clear (and this would assume the cyl is correct), then the powers are correct. Sometimes, when fitting toric lenses, the resultant powers don't always come out as one might mathematically predict. The doc can easily make the determination, so why not just ask to have it verified. LB, O.D. |

| Oops! Ignore my astigmatism readings. I used a calculator without making any adjustments to your Keratometry readings. |

Hm. Sounsd odd to me. Have you asked him to confirm that this is what> was more checking them against past ones, but he assigned both those on > the same day. I am 27 he meant to right?? My "back of the envelope" calc's say that your spec Rx should translate into approximately this .. for a toric soft lens: OD: -3.50 -2.00 x110 OS: -3.75 -1.50 x90 You sure you read it right (the left eye #)?? If you read it right, maybe he wrote it wrong. I'd check with him. Sounds like a slip-up. If it is, then it's good that you caught it. Again, though, I'm not a doc ... just a man ... like any other man ... only more so.... |

Or could this be correct? Were these prescriptions written as the result of two different eye exams on two different days, or did he measure you once and then write the glasses AND contact lens prescriptions?? How old are you?? |

| Hello, I recently had my eyes checked and I am not sure that my prescription is correct. The strength of the sph. reading is flipped for which eye is stronger between the contact lens and glasses prescription. I realize the prescriptions can be different, but I am not a huge fan of my eye doctor to begin with and I am suspicious there is a mistake here. Can somebody tell me if these prescriptions make sense together? Glasses: R: sph. -3.75 / cyl. -2.25 / axis: 110 L: sph. -4.00 / cyl. -1.75 / axis: 90 Contact lens: R: sph. -3.50 / cyl -2.25 / axis: 110 L: sph. -3.25 / cyl -1.75 / axis 90 It seems to me that one of the two is flipped - that tthe sph. is weaker on the contacts since they sit closer to my eye, but that perhaps the eyes are flipped? Or could this be correct? All the other aspects are the same... Please help! Josh |
