20D Double Aspheric Lens 57Mm Size Superior Quality
Perhaps the most recognized lens around the world, the Bawa 20D is the
lens that started the legacy of double aspheric lens design for BIO and is
still considered as a gold standard. The contributing factors for this are the
perfect balance of field of view and magnification of the 20D. The working
distance of 50 mm also makes lens manipulation a comfortable experience for the
examiner. This lens is perfect for general diagnosis of patients with a 3x
magnification and field of view that allows visualization up to the mid
peripheral region. The dynamic examination with the appropriate eye movements
by the patients allows viewing of the peripheral retina as well as detailed
examination by BIO in the primary position provides a comprehensive estimate of
retinal health. Thus, this lens is a great choice both as a first line of
diagnosis as well as a high level central retinal examination. the Common Size Of 20D Is 45mm In Market But We Makes 20D In
