Final answer:
The term 'green eye' is not typically connected to fixating or testing light. Instead, staring at a green dot and then watching a white screen leads to a negative afterimage due to retina cell overstimulation. Our eyes detect colors and shapes in our environment using visible light and test visual functions like convergence and accommodation.
Step-by-step explanation:
The term 'green eye' is not typically associated with either 'fixating light' or 'testing light' in the context of biology. When you stare at a green dot for a prolonged period and then look away to a white screen, you will experience a negative afterimage. This phenomenon is a result of the way our eyes and brain process visual information, particularly how light-sensitive cells in the retina become overstimulated and temporarily unable to respond.
Furthermore, when discussing the human eyes and how they detect light, we refer to the ability to see colors and shapes using visible light, as demonstrated when observing orange 'sea goldie' fish swimming in a coral reef. Testing eye movements involves assessing the eye's reactions to visual stimuli, such as convergence, accommodation, and the accommodation-convergence reflex, which are important functions of vision and eye health.
