Power of accommodation of the eye refers to the ability of the eye to adjust its focus in order to see objects at different distances clearly. This is achieved by changing the shape of the lens to bend light rays and bring objects into focus on the retina. The power of accommodation decreases with age, leading to presbyopia.
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
The far point is the maximum distance at which the eye can focus clearly without strain, typically around 6 meters in a normal eye. The near point is the closest point at which the eye can focus clearly, usually around 25 centimeters. These values can vary slightly among individuals.

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.
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.
The canthus refers to the corner of the eye where the upper and lower eyelids meet near the nose. You would find the inner canthus on the side of the eye closest to the nose and the outer canthus on the side of the eye away from the nose.
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.
The near point refers to the closest distance at which the eye can focus on an object. As we age, the lens in the eye becomes less flexible, making it harder to focus on close-up objects. This natural process is known as presbyopia, and typically begins around the age of 40. To counteract this change, reading glasses or bifocals may be necessary.
