bcoz our retinas bcome shrink. so it requires more light.
We need an source of light, an opaque object blocking the path of light, a screen behind the opaque object.
As people age, their eyes typically undergo changes that can affect their ability to see at night. This may include a decrease in pupil size, reduced ability to adjust to changes in light levels, and a decline in the sensitivity of the retina to low light. Overall, these age-related changes can make it more challenging for older individuals to see clearly in low-light conditions.
To see the Andromeda galaxy, you will need a telescope with an aperture of at least 6 inches (150mm). This is because Andromeda is a large galaxy and its light is spread out over a wide area in the night sky. A larger aperture will allow more light to enter the telescope, making it easier to observe.
You see more stars in the country because you are farther away from the bright city lights that drown out the dimmer light of the stars.
it uses light to help you see the object and it has more than on lensIt uses light to see, and it is compound because it uses more than 1 lens.

As people age, their eyes undergo natural changes that result in reduced pupil size, lens flexibility, and retinal sensitivity. This makes it harder for older individuals to see in low-light conditions, leading them to require more light when reading to alleviate eye strain and improve visibility.
Cats don't need as much light as humans to see well in the dark. Their eyes are adapted with more rod cells that can detect low light levels. Cats can see in light levels six times lower than what a human needs to see.
no because you need light to see
You don't see the objects themselves, but rather the light that has reflected off of them. That reflection travels toward us at the speed of light, and with enough distance we will see the object as older due to the amount of time it takes for the reflected light to reach us.
to see with their eyes they do
You only "see" when light enters your eyes. In the dark, there is no light . . . the main reason why we call it "dark". Since there is no light, none can enter your eyes, and you do not see.
The lens on the eye needs to widen to let more light in your eye so you can see more in the dark. It takes time so when the light is actually on, your lens is contracted but suddenly when the light is turned off, the lens takes time to widen so then your can see better.
to see
Tell him it isn't enough and that you don't want to see him anymore. If you need help consult with an older adult for more advice.
There are many reason one might require the use of a piano light. The most common reason would be that a pianist would need more light to see the sheet music.
To see a shadow, you need a source of light, an object to cast the shadow, and a surface for the shadow to be projected onto. When the light is blocked by the object, a shadow is created on the surface opposite the light source.
