Blurred vision is the most common symptom of refractive errors. http://johnlautner.net/refractive-error/refractive-error.html However, people with long sight cannot accommodate fully and so the light does not focus on the retina and vision is blurred.

Accommodation typically enables younger patients to overcome facultative and latent hyperopia.[1] Asthenopia (eye strain) and/or eye pain is commonly reported and is commonly associated with headaches due to close work such There is currently no widely accepted treatment to stop progression.
