binocular refraction
Apr 11, 2005 15:41:11 When doing a binocular refraction is it necessary to adjust the sphere by half of the cyl change or is this only for monocular refraction? |

Apr 11, 2005 19:26:30 its both and/or either. Depends on what you want to do and why. Your notes will say it all. Be creative - move away from rules. |

Examiners will not pass you if they do not believe you understand what you are doing. |

Apr 16, 2005 22:43:17 yes it is. its exactly the same as monocular refraction but under bin conditions so saves bin balancing at the the end. hope that answers ur question but yes do read up on the theory, i was asked in routine exam. |
