You are short-sighted. As a result you have problems seeing clearly in the distance.
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 too focused to be able to produce a sharp image on the retina. This can happen, for example, if the eyeball is too long. It is also possible for the cornea or the lens to focus the light too much. This means that things you see far away are blurred or you have to strain your eyes a lot to see clearly.
