is important to not only test the central vison but also at the peripherals of the retina. This is because individuals tend to not notice vison loss at the peripherals compared to central vision as when an individual views an object they move their eyes and fixate on that object by using their central vison and not their peripheral. Visual acuity is highest at the fovea and lowest at the peripheral which ensures high visual acuity at fixation. A way to measure peripheral vision is the Humphrey…

For example, after he had replaced all the floorboards “so cleverly” (Poe, p.8) he proceeds to explain that “no human eye-not even his-could have detected anything…
