Eye Health & Learning
Refractive error
Refractive error is a common reason vision may be blurred. It happens when the eye does not focus light on the retina in the way needed for a clear image.

Myopia
Myopia, often called short-sightedness or near-sightedness, generally makes distant objects harder to see clearly.
Hyperopia
Hyperopia, often called long-sightedness or far-sightedness, can affect how the eye focuses, particularly at near distances, although the experience varies by age and degree.
Astigmatism
Astigmatism relates to the optical shape of the eye and can cause blurred or distorted vision at different distances.
Assessment comes first
These descriptions are general. Symptoms alone cannot determine a prescription. An appropriately qualified eye-care professional should assess the learner and decide whether correction or another form of management is indicated.
