THE IDEA BEHIND THE PROJECT? THAT OF CREATING A SINGLE DEVICE AT A LOW COST ABLE TO PERFORM A HIGH NUMBER OF EYE SCREENING TESTS THAT, CURRENTLY, ARE CARRIED OUT THROUGH THE USE OF DIFFERENT DIAGNOSTIC TOOLS. WILL THE INSTRUMENT RESPOND? MAINLY WITH A GROWING NEED? PREVENTION OF SOCIALLY RELEVANT DISEASES (SOCIAL PATHOLOGIES). IN FACT, THERE IS AN INCREASING DEMAND ON THE INTERNATIONAL MARKET TO HAVE AN AUTOMATIC DIAGNOSTIC TOOL, SIMPLE TO USE, WIDESPREAD AND ABLE TO OPERATE WIDE-RANGING SCREENING. THE DEVICES CURRENTLY AVAILABLE ON THE MARKET ARE ABLE TO CARRY OUT ANALYSES WITH DIFFERENT TOOLS, OBLIGING THE PROFESSIONAL OR THE OPTICAL STUDIO TO PURCHASE MORE? DIFFERENT EQUIPMENT THAT, USUALLY, IS USED FOR ONLY A SMALL PART OF THEIR POTENTIAL. THE PROJECT, ON THE OTHER HAND, AIMS TO CREATE AN AUTOMATIC, SIMPLE MACHINE
