# LV MT2 Eq

 Ratio of comparisons Kestenbaums method Inverse of BCVA Conventional mag Mag = D/4 + 1 Effective mag Mag = D/4 Convergence demand Convergence = MA x PD (in cm)MA = 100/WD Prism for half eyes Plus power + 2 for each eye Equivalent power Fe = F1 + F2 - d(F1)(F2) HHM FoV W = d x (f/h)W = linear width of fieldd = diameter of lensf = focal length of magh = distance of lens from eye Equivalent power for electronic devices Fe = Mag x F2 Mag of telescopes Ma = -Foc/Fob Tube length Exit pupil of telescope/mag check Mag = (entrance pupil diameter)/(exit pupil diameter) Telemicroscope exact formula for vergence  whereL'oc = vergence leaving telemicroscopeL = divergent light hitting objective lenst = tube length (meters)Ma = mag of TS Approximate formula for telemicroscope divargence Approximate formula for telemicroscope divergence Stand mag equivalent power Feq = F2 x ER Lateral mag of a stand magnifier ER = (L'-F1)/L' = L/L' F1 = power of stand mag lens Working distance of stand mag f2 - l' Authormbills ID352528 Card SetLV MT2 Eq Descriptionequations Updated2020-07-14T12:09:24Z Show Answers
