How far the human eye can see

Ever wonder how far can the human eye see? We usually use tools that aid us in looking at far objects like binoculars, telescopes, etc. When it comes to seeing with the naked eye, many factors play a part in determining how far you can see. What is the range of the human eye? The range of vision for a person is infinite. You can see for miles and miles. On a clear day, you can see for up to 3 miles before the horizon due to the curvature of the earth. Yet you can see skyscrapers in a further distance than 3 miles due to no horizon obstruction. If you look into the sky you can see stars during the night that are millions of miles away. It is easier to see objects that are bright and big. For example, the moon, sun, stars, etc. The furthest you can see in the ocean is about 2.9 miles cause of the horizon limit due to the earth’s curvature.

Visual Acuity and Eyesight Your visual acuity is how clear your eyesight is. As some people stated that having 20/20 vision is the best. That refers to your visual acuity. 20/20 means you can clearly see something from 20 feet away. This plays a part when being able to see a certain distance. Here are ways to keep your eyes healthy and protected. Brightness affects distance The brighter the object the easier it is to see at a distance. The sun is 92.131 million miles away, yet we can see it in the sky. That is cause brightness plays a huge part when seeing an object in the distance. Line of sight The meaning of a line of sight is a straight line in which an observer has an unobstructed vision. Things like trees, buildings, clouds, etc. can affect your line of sight. There’s also the earth’s curvature that plays a part in visual obstruction. How the eye processes images When looking at anything, actions occur at lightning-fast speeds in the eye and brain. Light reflects off objects and passes through the cornea. Which is the transparent part of the eye that covers the iris and pupils. The cornea will bend light rays to allow light to enter. When light passes through it reaches the back of the eye to tiny nerve cells. These nerve cells are known as rods and cones, which convert light to electrical impulses. This travels through the optic nerve to your brain. This converts them into images.
