H52.4: Presbyopia
You are far-sighted. As a result you have problems seeing clearly up close.
The transparent cornea is on the outside of the eye above the pupil. The cornea is considerably curved. In this way, light is focused in the eye. This is vital to be able to see clearly.
Behind the pupil is the lens. The lens of the eye is oval, transparent, and seated within a firm capsule. The lens of the eye can bend to different degrees, thus focusing the light in the eye. This is vital if objects at different distances are to be seen clearly.
Rays of light enter the eye through the cornea and the lens. The image that you see then appears at the back of the eye on the retina. The light has to be focused just right for a person to see clearly.
In your case, the light is not focused enough to be able to produce a sharp image on the retina. This means that things you see up close are blurred or you have to strain your eyes a lot to see clearly. In your case, the reason for this is that your eyes can no longer adjust to different distances sufficiently. This is because of changes affecting the eye. These changes develop with age.
