REFRACTIVE IMPAIRMENTS
Hyperopia (farsightedness)
When the focal point for light is behind the retina making it difficult to see at close range. As a result headache, dizziness, nausea and eye fatigue may occur. Adaptations may be corrective lenses, and magnifiers. Educational considerations; variations in near and far tasks help reduce fatigue, student will prefer distance vision activities. Large print materials, and augmentative lighting may also be employed.
Myopia (nearsightedness)
Occurs when the image of a distant object focuses in front of the retina. This inability to see at a distance is often noticed by squinting and frowning. Corrective lens, high illumination with minimal glare are simple adaptations. Surgery is possible , but still experimental.
Educational consideration; Move student closer to blackboard and demonstrations. Allow freedom to move about room to obtain information when needed. Usually will not prefer physical education activities.
Astigmatism Blurred vision resulting from irregularities in the shape of the cornea.
