1. A method for determining specification parameters used to manufacture at least one ophthalmic lens, said specification parameters including one or more of: (i) optical and/or geometrical data relating to said at least one ophthalmic lens, and (ii) at least one parameter relating to a manufacturing process required to manufacture said ophthalmic lens, the method comprising:
training at least one neural network to predict said specification parameters used to manufacture the at least one ophthalmic lens, by using a training data set comprising a plurality of training prescription parameters and corresponding training specification parameters; and
predicting the specification parameters of said at least one ophthalmic lens by said at least one trained neural network, from prescription parameters relating to said at least one ophthalmic lens, based on said training.
