Near Point of Accommodation The closest distance from the eyes that reading material can be read. This distance varies with age. It is often measured in each eye separately and both eyes together. The results are compared to one and other. See accommodation and accommodative facility. |

Near Point Stress Term used when close work is causing the individual unacceptable stress. This is often seen when the relationship between accommodation and convergence is maintained only by excessive effort. The response to this is either a tendency to avoid close work (known as evasion) or alternatively, to use progressively more and more effort. This is typified by a tendency to get closer and closer to the work and then to suffer slower work rates, head aches and eye discomfort. Writing often becomes labored and difficult, showing a tight pencil grip and excessive pressure. They may complain of blurred vision, print getting smaller, colored fringes around text which sometimes moves on the page and possibly double vision. There is often a generalized ocular discomfort and there can be complaints of feeling 'washed out' after prolonged concentration. Symptoms can vary from day to day. |

Ocular Motilities A term used to describe the range of eye movements made by the eyes. These movements are controlled by six muscles on the outside of each eye known as extra-ocular muscles. Defects in any one of the muscles can cause inefficiencies in eye movement control and increased effort to maintain comfortable clear single vision. |
| |
Oculomotor Skills The ability to track or follow a moving object and the ability to move the eyes accurately and smoothly from one point to another. This is a vital skill in activities such as reading. |
