Hyperopia, or Long-sightedness, causes a person to see clearer at far than at near.
Extra effort is required to try to clear the focus at all distances, resulting in eye strain and fatigue. This “strain” can manifest itself as headaches after close work, blurred near vision, tired eyes, difficulty adjusting focus from distance to near and near to distance, avoiding close work and short attention span for near tasks.
Common symptoms are associated with tasks, which require continued visual concentration. It becomes a problem to maintain a clear focus on near objects; causing headaches and tired or aching eyes.
In some age groups, a prescription for hyperopia often works to relieve the strain, rather than clearing the vision.
