When light enters the eye through the cornea, the eye refracts or bends light rays and focuses them, creating an image on the retina.  Eyesight problems are caused when the perfectly dome shape of the cornea is out of shape and bends light in the wrong way.  This prevents the image from correctly focusing on the retina and vision becomes unclear.  This bending and focusing of light known as refraction, leads to refractive errors. 

Hyperopia is the refractive error, in which distant objects are seen clearly, but close ones are not focussed properly.  This problem can occur when the eyeball is too short or the cornea has too little curvature i.e. it is the wrong shape which, means the focal point is too long ('Long Sighted'). This prevents light, which enters the eye from focusing properly.  You can suffer from hyperopia at any age but when we are young, our lens can often correct the problem. However as we get older, close objects may be beyond the ability of the lens to correct.
