1. Far point

   In visual perception, the far point is the farthest point at which an object can be placed (along the optical axis of the eye) for its image to be focused on the retina within the eye's accommodation. It is sometimes described as the farthest point from the eye at which images are clear. The other limit of eye's accommodation is the near point. For an unaccommodated emmetropic eye, the far point is at infinity, but for the sake of practicality, infinity is considered to be 6 m (20 ft) because the accommodation change from 6 m to infinity is negligible. See visual acuity or Snellen chart for details about 6/6 (m) or 20/20 (ft) vision. For an unaccommodated myopic eye, the far point is closer than 6 m. It depends upon the refractive error of the person's eye. For an unaccommodated hypermetropic eye, incident light must be converging before entering the eye so as to focus on the retina. In this case (the hypermetropic eye) the focus point is behind the retina in virtual space, rather than on the retina screen. Sometimes far point is given in diopters, the inverse of the distance in meters (see Simple myopia). For example, an individual who can see clearly out to 50 cm would have a far point of 1 0.5 m = 2 diopters {\displaystyle {\frac {1}{0.5\ {\text{m}}}}=2\ {\text{diopters}}} .

1. Far point

   In visual perception, the far point is the point at which an object must be placed along the optical axis for its image to be focused on the retina when the eye is not accommodating. It is sometimes described as the farthest point from the eye at which images are clear. For an object to be imaged on the retina of an unaccommodated myopic eye it must be brought nearer until it occupies a position conjugate to the retina. This point is called the far point of the eye. For hypermetropic eye, incident light must be converging before entering the eye so as to focus on the retina. In this case the far point is behind the eye in virtual space, rather than in front of the eye. For emmetropic eye, the far point is at infinity, but for the sake of practicality, infinity is considered to be approximately 6m or greater since the vergence change from 6m to actual infinity is negligible.
