light, sound, temp, taste, smell and pressure are all proximal. Distal are the external source. They do not directly interact. Two methods that humans use to sift through all the proximal stimuli and organize it are gestaltism and perceptual sets.
Distal Stimulus: An object in the world that elicits a stimulus (lightbulb, tree, etc.) Proximal Stimulus: Stimulus that generates a nerve impulse. Ex: A lightbulb gives off light (or color) that acts a distal stimulus.
The way I learned it is that the distal stimulus is distant, so it is the bowling ball sitting away from you on the floor that you think you are thinking about. Proximal stimulus then is what actually stimulates you.
Based on what I've read on reddit and SDN: Distal Stimulus (in terms of sight): the actual that you are trying to sense; a ball, laptop, doggo, etc. Proximal Stimulus (in terms of sight): the neural on the retina and optic nerve that will be sent to the occipital lobe.

The proximal stimulus refers to the patterns of stimuli from objects that make contact with our sensory receptors, while the distal stimulus is the actual object that is present in the environment and is the source of the sensory input. By exploring these concepts, you’ll gain insights into:
In perception of light by the eye, the proximal stimulus refers to physical stimulation that is available to be measured by an observer’s sensory apparatus. In the case of the eye the diistal Stimulus is any physical object or event in the external world that reflects light.
