System for collecting and utilizing health data

A method of health monitoring, the method being carried out by a processor, the method comprising:

• determining, by an optical spectral sensor, biomarker characteristics of a user based analysis of a contact lens worn by the user;
• the processor collecting current health data of the user, the current health data of the user comprising the biomarker characteristics of the user received from the optical spectral sensor;
• the processor receiving archived health data of the user from a database;
• the processor aggregating the current health data with the archived health data;
• the processor analyzing the aggregated health data;
• and
• the processor correlating the aggregated health data to generate a recommendation,
• in the correlating, the processor using information that indicates correlation between aggregated biomarker characteristics and aggregated contact lens preferences, to determine a contact lens to be recommended for the user, in accordance with the biomarker characteristics of the user;
• and
• the processor notifying the user of the recommendation of the contact lens determined by the processor, wherein:
• the information that indicates correlation between the aggregated biomarker characteristics and the aggregated contact lens preferences is a predictor generated by performing machine learning of a contact lens preference of each of a plurality of users that is stored in the database;
• the optical spectral sensor comprises a light source and a light receiver incorporated into a contact lens container;
• and
• the optical spectral sensor is configured to measure a light transmittance through a solution containing biomarkers within the contact lens container using the light source and the light receiver.
