What are black and white or dim light vision a function of?
rods
Why pupils becomes bigger in Dim light?
To concentrate more light onto the retina.
Is night vision UV vision?
No. Night Vision equipment uses infra-red (IR) light, wavelengths of light longer (lower frequency) than visible light. Infra="below", red, or light below red light in the spectrum. UV stands for ultra (above)-violet, light that is above the violet light spectrum, so higher frequency=shorter wavelength.
A metaphor for stars?
Spoon full of stars by the dim light of the stars like a shooting star
What is bright?
the brightness of an object is the amount of light it reflects, the more it reflects the brighter it will be. Or the object could be giving out light, a vehicle head light for example
The dim light receptors are the?
rods are our or dim light and peripheral vision receptors
What are light sensitive cells that respond to dim light?
rods are our or dim light and peripheral vision receptors
What is weak vision in dim light?
nyctalopia
What are black and white or dim light vision a function of?
rods
Which retinal cells are responsible for vision in dim light?
rod cells
What is dichromatic vision?
Dichromatic vision is the ability for an animal to distinguish colors in dim light. It is the evolution of the basal mode of vision in animals.
What is the name of the cells that are used for vision in the dark or dim light?
rods or rod cells
How do rods and cones differ functionally?
Rods: dim light and peripheral vision receptors, more sensitive to light Cones: operate in bright light and provide high acuity color vision
Which sensor receptive cells in the retina that function best in dim light and enable night vision are?
cone
What type of nerve cells on the retina that allow to see dim light?
Rod cells are evenly dispersed across the retina and pick up light of all wavelengths as the same stimulus and so do not allow colour vision. The advantage of these cells is that they are sensitive to very dim light light and so are responsible for the limitted degree of night vision in humans.
Why can you sometimes see things from the corner of your eye even though they are so dim you cannot see them when you look directly at them?
This is called averted vision. The light receptors toward the outside of your normal vision field are better at picking up dim objects.
When your eyes are becoming weak why you are eating green vegetables?
because vitamin A is present in green vegetables which vision in dim light.
