Define power of accomodation of the eye?
The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or
What is th far point near point of the human eye with normal vision?
the far point of human eye is around infinitythe near point of human eye is 25 cm without strain
What is the closest point at which clear focus is possible?
''Near Point -- the closest ''point from the eye at which an object can be clearly seen.''''
What is the near point of vision?
The near point of vision increases with age because the elesticity of the lens decreases as we get older.near pointthe nearest point of clear vision, the absolute near p. being that for either eye alone with accommodation relaxed, and the relative near p. that for both eyes with the employment of accommodation
What do you mean by far point and near point of human eye and what is their values of normal eye?
Far point- it is the range till where our eyes can see and in a normal human being it is infinity.Near point- it is the nearest possible distance from our eye till which we can see an object clearly. it is 25 cm in human.
What is near point of vision?

Why would someone want their enemies near?
So that you can keep an eye on what they are up to!
What would be the visual result of an inability of the rectus and oblique muscles to function?
The eye would be unable to keep a moving object focused on the fovea centralis of the eye.
Is the London Eye near the Church of England?
The London Eye is near Westminster Abbey.
Is Optic chiasm the blind spot of eye?
No. The blind spot in the eye is the optic disc, the point where the optic nerve meets the retina. At this point, there are no photoreceptors, so no detection of vision. The optic chiasm is the place near the brain where the optic nerves cross over.
What does the lens in an eye do?
Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.
How does the focal length of eye changes from a near object to far object?
When you're looking at a near object, the light rays converge at a point behind the retina so the focal length of your eye increases so that the parallel rays of light converge on the back of the retina. Therefore, if you're looking from a near object to a far object, the focal length of your eye should decrease back to its normal, relaxed size.
