Method for Selecting Base-Curves for an Ophthalmic Lens and Related Spectacle Lens Manufacturing Method |
摘要 |
A method for selecting base-curves for an ophthalmic lens according to given prescription data comprising the steps of: providing a base-curve series consisting of a plurality of base-curves; calculating a target lens according to the prescription data; calculating the base-curves calculated lenses according to the prescription data; selecting, for at least an optical parameter and/or a geometrical parameter, a threshold value for the difference between the base-curves calculated lenses values and the target lens value of said parameter(s); determining the list of the base-curves of the base-curve series where said difference for said parameter(s) is less or equal to the selected threshold value(s).
