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.",
