Hyperopia

Hypermetropia, or long sightedness, is caused when the eye is shorter or weaker than normal. This causes light rays to be focused to a point behind the retina, making closer objects appear blurred whilst distant objects may feel clearer. Placing a plus or convex lens in front of the eye pulls the focal point forward into the retina.

An element of hypermetropia is common in many people usually only creating problems when our ability to focus is notably affected or when suffering with eye strain and headaches.
