The minimum distance an object can confortably be held in focus
the far point of human eye is around infinitythe near point of human eye is 25 cm without strain
The near point is the closest distance at which the eye can focus clearly. It is important in vision and eye health because it indicates the ability of the eye to accommodate and adjust focus for near objects. Changes in the near point can be a sign of age-related vision changes or eye conditions.
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 near point of the eye is the closest distance at which an object can be seen clearly. It is significant in determining the optimal distance for reading and other close-up activities because it helps to identify the point at which the eye can focus most comfortably and efficiently. This distance is important for preventing eye strain and maintaining clear vision during tasks that require close focus, such as reading or using electronic devices.
The London Eye is near Westminster Abbey.
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.
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.
