Web3. mar 2024 · Refractive status, evaluated by spherical equivalent and astigmatism, is a basic optical property of the eye, which sets fundamental limits to the visual acuity that can be achieved without correction [ 1 ]. Refractive errors are present when parallel rays of light do not focus on the retina, and lead to blurred images.
