| 6J10.00 | The Eye | | |
| 6J10.10 | eye model | PIRA 500 | |
| 6J10.10 | eye model | 6J10.10 | |
| 6J10.10 | model of the eye | Og-8 | Show a take apart model of the eye. |
| 6J10.10 | eye model | O-5b.1 | The standard take apart eye model. |
| 6J10.21 | water flask model of the eye | 34-2.1 | A
large flask filled with water, a little fluorescein, and some external lenses
make a model of the eye in near and far sighted conditions. |
| 6J10.21 | eye models | L-65 | A spherical lens
filled with milky water represents the eyeball. Use a large lens in front
of the sphere to show inverted image, near and far sightedness. |
| 6J10.30 | blind spot | PIRA 1000 | |
| 6J10.30 | blind spot | 6J10.30 | Same as L-58. |
| 6J10.30 | blind spot | L-58 | Move a white cross toward a white spot on the blackboard while the students close one eye. |
| 6J10.40 | inversion of image of retina | PIRA 1000 | |
| 6J10.40 | inversion of image on retina | L-59 | A
small tube has three holes in a triangular pattern drilled in one end and
a single hole in the other. Hold the triangular end near the eye and the
pattern appears inverted. |
| 6J10.50 | astigmatism | L-64 | Look at a chart of radial black lines. |
| 6J10.55 | eyeglasses | L-66 | Project an image
of concentric circles crossed by radial lines. Place a lens and then a correcting
lens over the projection lens. |
| 6J10.60 | chromatic aberration of the eye | L-63 | A purple filter is mounted in front of a straight filament lamp. |
| 6J10.80 | resolving power of the eye | PIRA 1000 | |
| 6J10.80 | resolving power | L-86 | The limit of
resolving two filaments of an auto headlamp is 25 - 30 feet. ALSO - show
slides of the "Navicula" made with green and UV light. Reference. |
| 6J10.81 | resolving power with TV | PIRA 1000 | |
| 6J10.81 | resolving power | Disc 23-09 | The camera
zooms in on a vertical series of back illuminated double slits, each separated
by half the distance of the preceding pair. |
| 6J10.85 | Computer generated Sayce chart | AJP 58(6),552 | A
valuable background discussion on the resolution of the eye and a computer
generated Sayce is shown. An external slit is used to stop down the eye pupil. |
| 6J10.90 | locating images by parallax | 34-1.14 | An arrangement is shown for locating real and virtual images by parallax. |
