The mechanism of “seeing” is quite simple. When you focus on an object, the rays of light that reflect from that object enter your eye and then focus on your retina, which is very sensitive to light. The retinal cells than sent messages to the brain via the optic nerve and the brain interprets these messages, owing to which we “see” the object.
In optometric terms, 20/20 vision is simply normal vision. In other words, it is visual acuity and sharpness measured at a distance of 20ft from the object in focus. If your vision is found to be 20/20, you can see the object clearly when you stand at a distance of 20ft from it. If your vision is found to be 20/100, you have a reason to worry because you need to come as close as 20ft to the object while a person with 20/20 vision can see it clearly even from a distance of 100ft.
Your Child’s Vision
A huge majority of newborn babies are farsighted, which means that they are unable to see things that are close to them, but have no problem seeing things that are far away from them. A small percentage of newborns are myopic, which means that they can see things only if they are brought closer. Many babies are born with normal vision. These visual abnormalities usually normalize as the child grows up.
