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. This process is also known as refraction.
In your case, the light is not focused in a way that produces a sharp image on the retina. This can result in a person finding it more difficult to see up close or in the distance, for example. There can be different reasons for this.
