Why should the lens of a normal eye be fatter to look objects and thinner to look at distant objects?
The lens of a normal eye adjusts its shape to focus light properly on the retina, a process known as accommodation. When viewing nearby objects, the lens becomes thicker (fatter) to increase its curvature, allowing it to bend light more sharply to focus the image. Conversely, for distant objects, the lens flattens (becomes thinner), reducing its curvature and enabling the light to focus accurately on the retina without distortion. This dynamic adjustment ensures clear vision across varying distances.

What is the name of the condition for someone that requires no corrective lenses to focus on distant objects?
The condition is called emmetropia. This means that the person has normal vision and can see distant objects clearly without the need for corrective lenses like glasses or contacts.
Do all objects fall towards the center of the earth?
Yes, all objects on or near Earth's surface fall towards the center of the Earth due to the force of gravity acting upon them. This is why objects dropped from a height fall downwards.
What is a star like object is very bright and distant?
If this is a homework question the answer you are probably looking for is Quasar [See related question] However, the actual question is full of inconsistencies. Brightness is defined as being observed from Earth and distance is relative to your frame of reference - Apparent magnitude [See related question - Apparent magnitude] Therefore, a bright object could be the Sun, and in normal relative terms it is distant, to some very distant. A quasar on the other hand is not very bright from Earth but it is very very distant. For the question to fit the answer, the question should be "What star like object is very luminous and very far away". or "What star like object has a high absolute magnitude and is very distant [See related question - Absolute magnitude]
Why is a normal eye not able to see clearly objects placed closer than 25cms?
Light from objects that we see has to be focused by the eye to give a sharp image on the retina. Light from near objects is very divergent (spreading out), and the lens of the eye has to become very thick to focus it. As there is a limit to how thick we can make the lens, there is a near point beyond which we cannot focus.
What term refers to the force by which all bodies are attracted to the earth?
normal force
Why should the lens of a normal eye be fatter to lookat near objects and thinner to look at distance object?
The lens of a normal eye changes shape to focus on objects at varying distances. When looking at near objects, the lens needs to be thicker to refract light properly onto the retina. Conversely, for distant objects, a thinner lens is needed to allow the light to converge properly on the retina for clear vision.
Why should the lens of a normal eye be fatter to look at near objects and thinner to look at distant objects?
The muscles around the lens of your eye push and pull it thicker and thinner to focus your eye on an object depending on the distance from your eye to the object. The focal length of a fat lens is shorter than the focal length of a thin lens (the light rays are bent more sharply) When you focus binoculars, you are adjusting their focal length
What are the differences in vision between a myopic eye and a normal eye?
A myopic eye, also known as nearsightedness, can see nearby objects clearly but struggles to see distant objects clearly. In contrast, a normal eye can see both nearby and distant objects clearly without any difficulty.
What are the key differences between myopia and normal vision?
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.
What is the name of the condition for someone that requires no corrective lenses to focus on distant objects?
The condition is called emmetropia. This means that the person has normal vision and can see distant objects clearly without the need for corrective lenses like glasses or contacts.
How do you know when your hamster is having a baby?
if it is fatter than normal.
Is the normal resting eye generally set for distant vision?
The normal resting eye can see distant objects, but they do appear blurrier and less colourful. Take mountains for an example. I can see them a province away while I'm on crowfoot, but they look a very light gray. Hope I helped :3
Why do short girls tend to have larger breasts compared to normal height girls?
cos they tend to be fatter :D
How can you tell when a lizard is about to lay her eggs?
she would normally be fatter than normal, ONLY if your feeding her normally, Brand0n
What are the different types of eye ball shapes and how do they affect vision?
There are three main types of eye shapes: normal, nearsighted (myopic), and farsighted (hyperopic). The shape of the eye affects how light is focused on the retina, which can impact vision. Nearsighted eyes are longer than normal, causing distant objects to appear blurry. Farsighted eyes are shorter than normal, making close-up objects blurry. Normal eyes have a balanced shape for clear vision at various distances.
What happens when a persons ventricles have thinner walls then normal?
it breaks more easily
Is it normal for someone to be distant after someone dies?
yep at some stage.
