H52.4: Presbyopia
You are far-sighted. As a result you have problems seeing clearly up close.
The cornea is located at the front of the eye. It is transparent and curved. The curvature focuses light in the eye. This is vital to be able to see clearly.
The lens of the eye is located behind the pupil. The pupil is a round hole in the iris. The lens of the eye is transparent and lens-shaped like a magnifying glass. It lies in a fixed, transparent capsule made of connective tissue.
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.
