For World Sight Day 2016, Essilor Italia in collaboration with COMiB organized three days of free vision screening to its staff. The optometric tests, which include the assessment of the visual function and the determination of the refractive correction, were performed by qualified optometrists with the aid of some students in Optics and Optometry. In order to give a health care service, the university clinic provides free eye exam and eyeglasses to people in financial need; these examinations are carried out by final year optometry students under the supervision of qualified optometrists. This initiative is organized thanks to the support of the municipality of Milan, Opera San Francesco Onlus, Federottica, Luxottica and Hoya Lens Italia.
