Where is the human blind spot?
Light gets into the eye by passing through the pupil, the then hits the retina at the back of the eye, the **retina** is covered with light-sensing proteins. They relay what they sense to the optic nerve which carries the information back into the brain. The problem is, the optic nerve ends in the field of the retina itself. This is a little like having to plug the power cable for a TV directly into the screen. It creates a dark spot. Most of the time, the other eye will see what's happening in its partner's blind, but if the blind spots overlap while looking at a certain object, or if the person is only looking through one eye, the brain just fills in the spot looking at the surrounding picture.

How to find the blind spot of your eyes
To find the **blind spot** of your eyes you can do the following test, for the right and left eye.

**Right Eye**
Keep your head motionless, close your left eye (or cover it), have the right eye about 3 or 4 times as far from the screen as the red line, look at each character in turn, until the black circle is no longer visible.
 * To find the blind spot of your right eye do the following:**

**Left Eye**
Keep your head motionless, close your right eye (or cover it), have the left eye about 3 or 4 times as far from the screen as the red line (above), look at each character in turn, until the black circle is no longer visible. media type="youtube" key="L_W-IXqoxHA" width="475" height="350" align="center"

How to reduce/eliminate blind spot
Students in driving lessons are often taught to set the outside mirrors in a frame where both sides of the car are visible. However, with the development of the studies around the existence of blind spots, and how to avoid them, experts believe that this is not the most suitable orientation for the mirrors. This method produces an overlap between the area covered by the rear view mirror and the areas covered by the outside view mirrors. With this configuration the view will be duplicated, when it should be a complement between what is shown with the different mirrors, possibly originating a blind spot big enough to hide an entire vehicle approaching from either the rear or any side. As a result, the same experts consider that the accurate side mirrors’ position is obtained by rotating both of them 15 degrees outward. Like exposed on this figure, with this mirror’s configuration there is a large reduction in the blind spot. The following video shows more information on how to adjust your side view and rear view mirrors properly to avoid blind spots.


 * **Term** || **Definition** ||
 * Blind Spot || An area where a person's view is blocked ||
 * Retina || A layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed. ||
 * Rear View Mirror || A rear-view mirror, is a mirror in vehicles, designed to allow the driver to see rearward through the vehicle's backlight (rear windscreen). ||
