Photopic vision: Vision under well-lit conditions which provides for color perception,and which functions primarily due to cone cells in the eye.
Scotopic vision: Monochromatic vision in very low light which functions primarily due to rod cells in the eye.
The photoreceptors commonly referred to as "Rods", which are found in the retina, are responsible for night vision. (scotopic vision) "Cones" are responsible for colored vision with brighter light conditions. (photopic vision)
There is no scientific evidence to suggest that gender directly affects color vision. However, some studies have found differences in color perception between males and females, with women generally having a slight advantage in differentiating between shades of color. These differences are thought to be influenced by a combination of biological, environmental, and cultural factors rather than gender alone.
Dogs have more rod cells in their eyes, which help them see better in low light, while humans have more cone cells for color vision. This means dogs have better night vision but poorer color perception compared to humans. Additionally, dogs have a wider field of view and better motion detection, while humans have better depth perception and visual acuity. These differences in eye structure affect how dogs and humans perceive and interact with the world around them.
Dogs have better night vision than cats because they have more rod cells in their eyes, which are sensitive to low light. Cats, on the other hand, have more cone cells, which are better for seeing in bright light but not as effective in low light conditions. This means that dogs can see better in the dark compared to cats.
Long-sightedness, also known as hyperopia, occurs when the eye is unable to focus on nearby objects. Short-sightedness, or myopia, happens when the eye struggles to see distant objects clearly. Long-sightedness can cause blurry vision up close, while short-sightedness results in blurry vision far away. Both conditions can be corrected with glasses or contact lenses.

What is the difference between the artillerymans Vision and look at this
Rods are the photoreceptors that are not used in color vision. Rods are much more plentiful than the cones, and much more sensitive, they are responsible for scotopic vision.
explain the difference between binocular and panoramic vision
Cones are responsible for photopic vision, meaning they are sensitive to color and provide all high definition vision. They are specifically sensitive to 3 colors of light; Red Green and Blue.
night blindness is particularly caused by deficiency of vitamin A (retinol)Our eyes contain 2 photosensitive cellsrods-for scotopic vision i.e., for night vision contain pigment rodopsincones-for photopic vision i.e, to see colours in presence of light contain pigment ionopsinrodopsin pigment contain retinal, an aldehyde of retinol(vitamin A)Therefore deficiency of vitamin A effects scotopic vision and is known as night blindness
Infrared technology detects heat emitted by objects, while thermal vision technology creates images based on temperature differences. Thermal vision is more advanced and can provide more detailed images than infrared technology.
Several forms. Light striking your eyes is light energy, photons, in the visible spectrum. In your eye the light energy is converted to chemical energy, which then triggers ions to move in the neurons of the optic nerves, which then releases an electrical potential charge through nerve cell. Then at the end of the nerve, the synapses releases chemicals that carry the energy to the next nerve cell, which changes it back to electrical energy by ions created to create an electrical potential nerve cell. This feeds through various components of the optic nerve system including the two nucleates nuclei to the occipital cortex at the back of the brain, and from there to the temporal and the parental lobes of the brain for interpretation of what you are seeing.
In the human eye, cones look like a cone, while rods look like short rods. Rods are connected in "parallel", and they detect minimal amounts of light. Cones tend towards a "serial" transmission to the nervous system. Cones also come in various types -- red detecting, green detecting, or blue detecting -- so they enable color vision. Books have been written on this subject, and I wrote a short paragraph.
Myopia, also known as nearsightedness, is a refractive error where distant objects appear blurry. It occurs when the eyeball is too long or the cornea is too curved. Normal vision, on the other hand, allows for clear vision of both near and distant objects.
For maximum utilization of scotopic vision( a vision of eye in low light), 20 to 30 minutes in total darkness are required to attain satisfactory retinal dark adaptation. An alternative is to have the aircrew member wear red goggles for 20 to 30 minutes before flying. When worn in normal illumination, red goggles will not interfere significantly with the ability to read most maps, charts, manuals, etc., as long as the printing is not in red ink. Red goggles block all light except red, which enhances rod dark adaptation because red light does not stimulate the scotopic system.
