Transpose
Transpose the sphero-cylindrical formula, for negative and positive cylinders. Representation of the optical cross.
Distometry
Transpose the sphero-cylindrical formula, for negative and positive cylinders. Representation of the optical cross.
Now you can put the vertex distance of the initial prescription and calculate the prescription at a certain vertex distance.
Overcorrection
Calculate the theoretical power after over-refracting the patient with the lenses, taking into account the turn.
Addition
Theoretical calculation of the power that we have to add in near vision and in medium distance depending on age and distance.
Thicknesses
This application calculates the thicknesses of a lens approximately. For the exact calculation it is necessary to know more specific parameters.
To know the exact theoretical thickness use the programs of the lens providers.
Important: The thickness measurements are approximate. The volume and weight measurements are indicative.
