Vision 1• Learning Goals:

– Students should be able to answer the following:

1. What is the energy that we see as visible light?

2. How does the eye transform light energy intro neural messages?

Rating Student Evidence

4.0 Expert

I can teach someone else about how we see energy as visible light and how transduction occurs in the eye. In addition to 3.0 , I can demonstrate applications and inferences beyond what was taught

3.0Proficient

I can analyze about how we see energy as visible light and how transduction occurs in the eye and compare/contrast the Aspects of the learning goal.

2.0 Developing

I can identify terms associated about how we see energy as visible light and how transduction occurs in the eye, but need to review this concept more.

1.0Beginning

I don’t understand this concept and need help!

Vision & Energy

• Light Characteristics

1. Hue (color)

– the dimension of color determined by the

wavelength of the light

2. Wavelength

– Different wavelengths of light

3. Intensity

– Amount of energy in a wave determined by

amplitude. It is related to brightness

Transduction

• Transduction is a process by which light

is converted into electrical signals in the

rod cells, cone cells and photosensitive

ganglion cells of the retina of the eye.

Pupil = the adjustable opening in the center of the eye through

which light enters.

Iris = a ring of muscle tissue that forms the colored portion of the

eye around the pupil and controls the size of the pupil opening.

• The iris dilates/constricts in response to changing light intensity

Lens = the transparent structure behind the pupil that changes

shape to help focus images (accommodation) on the retina.

Retina = the light-sensitive inner surface of the eye, containing the receptor

rods and cones plus layers of neurons that begin the processing of visual

information.

Blind Spot = the point at which the optic nerve leaves the eye,

creating a “blind” spot because no receptor cells are located there.

Fovea = the central focal point in the retina, around which the

eye’s cones cluster. (cones-color, rods-b/w)

The fovea allows for line of sight is a virtual line between the fovea and

a fixation point that allows for 100% visual acuity (sharpness)
