Patients with this kind of prescription are able to see well up close but things at distance are out of focus.įarsighted (hyperopia) means the focusing system of the eye is too weak or the axial length of the eye is slightly too short such that the image is in focus behind the eye instead of in perfect focus on the fovea of the retina.
Nearsighted (myopia) means the focusing system of the eye is too strong or the axial length of the eye is slightly too long such that the image is in focus in front of the retina instead of in perfect focus on the fovea of the retina. What is the difference between nearsighted and farsighted?
