Hyperopia or long-sightedness makes it more difficult to focus on closer objects.  As well as noticing blurred near vision, long-sighted people often suffer from sore, tired eyes and/or headaches when doing close work.  Although hyperopia primarily affects near vision, it can also affect distance vision too, and somewhat paradoxically being long-sighted does not necessarily mean that distance vision will be good.  Hyperopia is usually well corrected with spectacles or contact lenses; these may not need to be worn all the time and in some circumstances only for close work.
