objects from each other with greater precision. Visual acuity is the sharpness with which an object is focused on the retina. Reduced visual acuity Visual acuity is influenced by a wide variety of factors [...] the eye media, the retina or the optic nerve can lead to reduced visual acuity. Visual acuity in ophthalmology However, determining visual acuity is also an absolute necessity when using magnifying vision [...] and opticians need to determine the corrected visual acuity (lat. visus cum correctione) - i.e. your best corrected visual acuity. The determination of visual acuity is not only necessary for fitting glasses
