Science - All About the Eyes!

When you wake up in the morning you simply expect to be able to see but in order for the eye to see, a number of things must occur. It must detect a light source and the light source must reflect off of an object. That light will then travel through the clear cornea of the eye. It passes through the lens and focuses the light onto the retina. The retina inverts the image so it is upside down. When the signal of the object is then transmitted to the brain, the brain makes a correction and flips the image back and then relays the image as being right-side up. Having two eyes working simultaneous then helps us to be able to detect depth and perception and it allows us to see in 3-D dimension.

Now let’s see what that very same paragraph looks like in Spanish.

Cuando usted se despierta por la mañana solo espera poder ver, pero para que el ojo pueda ver deben ocurrir una serie de cosas. Se debe detectar una fuente de luz y la fuente de luz debe reflejarse sobre un objeto. Esa luz viajará luego a través de la córnea transparente del ojo. Pasa a través de la lente y enfoca la luz hacia la retina. La retina invierte la imagen y, por lo tanto, está al revés. Cuando la señal del objeto se transmite al cerebro, el cerebro hace una corrección y voltea la imagen, y, entonces, transmite la imagen enderezada. Tener dos ojos que trabajan simultáneamente nos ayuda así a ser capaces de detectar la profundidad y la percepción y nos permite ver en 3-D.

Practice reading that paragraph in Spanish. By the eyes seeing the Spanish words, the brain begins to learn how to quickly recognize what each word means. Don’t worry, you won’t have to write paragraphs just yet but this is a good eye exercise. However, as you may recall, the eye is made up of many parts. As you have already learned these parts, no detail descriptions will be given here. Rather, you will see the English word parts and their corresponding Spanish word parts. After you have studied each part, move directly to the quiz section.

THE EYE

QUIZ TIME!

The quiz will give you a description of the parts of the eye and you will need to locate the Spanish word for what the description is referring to. Now let’s take a look at just how much you can see.
