Eye
Definition

The eye is constituted by three key elements to be able to take advantage of the light:

- the lens adjusting light, about it more in the section on lenses

- the system that registers light and the nervous system that carries information to the brain

- the brain that processes the information received

In this section we will dedicate ourselves to the last point, since it is the point that defines what our eye captures.

See
Note

There are two key aspects in the way we see.

On the one hand is the mechanism as we segment what we see in multiple sub-fields that we analyze individually. This analysis then focuses on recognizing known patterns.

Secondly, there is our ability to recognize the objects in each of these subfields. This requires being able to recognize an object and its spatial position.

Eye Lenses
Quote

Our eye is able to adjust the focal length of the lens and thereby focus on objects in a very wide range of distances.

In case the lens is not able to adapt the focus in said range, optical lenses can be used that modify the range that is able to focus it.

Equations

Una relaci n se puede armar con los tri ngulos del lado del objeto. En este caso la similitud nos permite escribir que el tama o del objeto a_o es a la distancia del objeto s_o al foco f es como el tama o de la imagen a_i es a la distancia del foco f:\\n\\n

$\displaystyle\frac{a_o}{s_o-f}=\displaystyle\frac{a_i}{f}$



Con la relaci n de similitud de los tri ngulos

$\displaystyle\frac{ a_o }{ a_{lc} }=\displaystyle\frac{ s_o }{ s_{lc} }$



se puede mostrar que se cumple:

$\displaystyle\frac{1}{ f_{lc} }=\displaystyle\frac{1}{ s_o }+\displaystyle\frac{1}{ s_{lc} }$
