Study of some ophthalmic lenses and their effects on the retinal image and vision. Study of optical aberrations, with related effects on vision. Progressive addition lenses; special ophthalmic lenses.
Radiometry and Photometry. Light sources: evaluation parameters and operating principles. Hints of Colorimetry
Acquisition of skills on the optical effects induced by different types of ophthalmic lenses on the retinal image and on the vision, in order to understand the best use of these lenses in the supply of optical aids for the correction of refractive error or other vision anomalies.
