      note          = "ABSTRACT Myopia is a refractive defect that affects 27% of
                       the world population. Its incidence increases in an
                       accelerated way becoming a public health problem, with an
                       economic and social impact. Recent studies have observed a
                       direct connection between the myopia development with a
                       growth of the axial length of the eyeball, due to the
                       refraction in myopic is hypermetropized towards the
                       periphery and can lead to the eyeball growth as a mechanism
                       to achieve clarity in it. The main goal of this study is to
                       evaluate the subjective visual quality with two types of
                       Dual-Focus contact lenses to 10 patients in total. Viasual
                       acuity was assessed in photopic and scotopic conditions and
                       with 30% contrast. Also, it was measured deep vision (or
                       stereopsis) and the measurement of night vision halos. In
                       the end, it was carried out a questionnaire of quality and
                       comfort to patients after putting them on. The results
                       obtained are that Lens A has a higher visual quality than
                       Lens B. Regarding visual acuity, both lenses provide good
                       results. Visual acuity with low contrast decreases slightly
                       with Lens B. Stereopsis is worse with Lens B and
                       additionally, this produces more halos. Finally, patients
                       have difficulty focusing going from far to close visión
                       using Lens A the first days, symptom that with Lens B
                       doesn’t happen. And besides, the use of Lens A is more
                       comfortable than Lens B.",
