Farsightedness or hyperopia. This refractive error needs a plus power or magnifing lens to cause the light to focus sooner and thus, on the retina for clear vision.

If images focused on the retina are inverted how do you see the worl in its proper perspective?
You see objects because they reflect light rays. As light travels to your eyes, the lens focuses the image of the object on the retina. The image of the object in the retina is inverted. As the image is formed, the optic nerves send the message to the brain. It is the brain that interprets and corrects the inverted image into an upright position. - Science Links by Sugpatan, Parde and Apolinario
How do lenses correct your eyes?
Corrective lenses, whether they are contacts or regular glasses, work on the principle that light travels at a different speed through the glass compared to air. When the light hits the lens, the light rays are bent to correct for the amount the lens in your eye needs correcting. Only your optometrist can determine this.
What captures the image in the eye?
The retina is where the image is formed.
Why is it important for your eye to contain a lens?
Without the lens in your eye you can not form a image on the retina. As the retina is kept at a fixed distance you change the thickness of the lens to get the image on the retina.
