Hypermetropia (long sightedness)
Hypermetropia occurs when the eyeball is too short for the focusing power of the eye, causing blurred vision for close objects. To correct this, the eye can accommodate (i.e. use the natural lens to increase the power of focusing and bring the image onto the back of the eye), however as an object comes closer more effort is required to focus the image and eventually the eye simply cannot focus strongly enough. Thus if you have hypermetropia you may tire easily when reading or doing close work, as the effort required to focus is greater than usual.
Hypermetropia can be corrected with refractive surgery and Mr Gerard Ainsworth would be pleased to discuss options with you.
