Spatial light modulator (IMAGE) Optica Caption The researchers used a spatial light modulator — shown here being illuminated by the interrogating beam — to reproduce, for the first time, real aberrations produced by different angles of illumination for different myopic eyes. This allowed them to rigorously analyze different types of eyeglass lenses that are used to slow myopia progression.
