Arrangement with a spectacle lens having a changeable effect and method for setting the effect of a spectacle lens

摘要

The invention relates to an arrangement with a spectacle lens having a changeable optical effect and with an effect-setting apparatus for setting the optical effect of the spectacle lens on the basis of intended-setting data. A memory apparatus stores first intended-setting data for setting a first predetermined optical intended effect, which was established from a first refraction measurement on an eye of a spectacles wearer for whom the spectacle lens is destined, and for storing second intended-setting data for setting a second predetermined optical intended effect, which was established from a second refraction measurement on the eye, and also a supply apparatus for supplying the first intended-setting data or the second intended-setting data to the effect-setting apparatus.

主权项

1. An arrangement comprising:
a spectacle lens with changeable optical effect; an effect-setting apparatus for setting the optical effect of said spectacle lens based on intended-setting data; a memory apparatus for storing first intended-setting data for adjusting a first predetermined optical intended effect; said first predetermined optical intended effect being determined from a first refraction measurement on an eye of a spectacle wearer for whom said spectacle lens is specified; said memory apparatus further being for storing second intended-setting data for adjusting a second predetermined optical intended effect; said second predetermined optical intended effect being determined from a second refraction measurement on said eye; and, a supply apparatus for supplying said first intended-setting data or said second intended-setting data to said effect-setting apparatus; wherein said first optical intended effect is an effect determined from a refraction measurement on said eye carried out under a first contrast condition and said second optical intended effect is an effect determined from a refraction measurement on said eye carried out under a second contrast condition departing from said first contrast condition.
