Assembly Instructions

Instructions
The eye is represented by a large flask filled with water and fluorescein dye to make the beam of light visible within it. Different lenses can be used to simulated normal, nearsighted and farsighted vision. Set the projector about two feet from the flask; now, place the lens marked NORMAL in the path just in front of the flask and adjust the projector so that the cone of light in the flask just converges at the back of the flask. This setup corresponds to normal vision. ​
