A method for determining, for a given person, an optical equipment among a set comprising a plurality of optical equipments. The method further includes collecting a plurality of N reference datasets associated to at least one corresponding reference person and collecting a given dataset associated to the given person. Each dataset is indicative of a relative ranking of at least two optical equipments forming a reference subset of the set of optical equipments. The method further includes, based on the given dataset, selecting, among the plurality of N reference datasets, a group of R reference datasets, and predicting at least one optical equipment for the given person among the plurality of optical equipments.

A server includes processing circuitry configured to receive one or more images, the one or more images including one or more representations of people. Additionally, the processing circuitry is configured to apply a neural network to the one or more images, wherein the neural network classifies at least one aesthetic component of each image of the one or more images, an aesthetic component score being generated for each image in the one or more images. Further, the processing circuitry is configured to generate a user eyewear equipment profile for a user, the user being matched to a persona from a personae database, each persona in the personae database being linked to one or more persona eyewear equipment profiles, the one or more persona eyewear equipment profiles being based on the aesthetic component score, and select eyewear equipment for the user based on the generated user eyewear equipment profile.
