The image is then carried through the optic nerve to the brain to create the image we see.
Nearsightedness is the inability to see objects far away.
When the cornea is too steep or the eye is too long, light rays are not in focus on the retina, resulting in blurred vision for distant objects. When the cornea is too flat or the eye is too short, light rays from distant objects fall behind the retina and are blurred. Farsighted individuals need glasses to see up close. Although distant objects appear clear, Past the age of 40, eyeglass correction is usually required. Astigmatism occurs when the shape of the eye is not round.
