Document Summary

Rattlesnakes can see infrared waves: wavelength plays an important role in the perception of colour. Intensity plays an important role in the perception of brightness. Increases the ability of the lens to refract (bend: when we focus on a distant object, the lens is flattened, process of adjusting the configuration of the lens is called accommodation. In the scotopic system, the output of several hundred rods converges on a single ganglion cell. Eye movement: the eyes continually scan the visual field and our visual perception at any instant is a summation of recent visual information, because of this temporal integration the world does not momentarily vanish when we blink. Involuntary fixational eye movements are of three kinds: tremors, drifts and saccades (small, jerky movements or flicks) Visual transduction: the conversion of light to neural signals: transduction is the conversion of one form of energy to another, visual transduction is the conversion of light to neural signals by the visual receptors.
