Web7 nov. 2024 · The magnification in DO can be easily obtained by the lens equation as D/4 — where D is diopter of the observed’s eyes — for a perfect/emmetropic eye, it is 60 [24]. The 4 in denominator comes from dividing 100 cm by the near point distance, 25 cm, used for reference as being the minimum distance where human eyes can form an image. WebHumans have binocular vision, meaning that we see with two eyes, not just one. This allows us to have a fairly wide field of view: 180 degrees, give or take a few degrees of peripheral vision.
