the far point of human eye is around infinitythe near point of human eye is 25 cm without strain
''Near Point -- the closest ''point from the eye at which an object can be clearly seen.''''
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
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.

So that you can keep an eye on what they are up to!
The eye would be unable to keep a moving object focused on the fovea centralis of the eye.
The London Eye is near Westminster Abbey.
The focal point is in front of the retina
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.
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.
