Myopia, also known as nearsightedness, can make it difficult to see objects at a distance, though you can see near distances.
Hyperopia, also known as farsightedness, is a refractive error that makes it difficult to see up close, such as when reading or working at the computer. However, your distance vision is not affected.
Astigmatism prevents light from coming to a single focus on the retina. This error can create distorted, blurry, or fuzzy vision.
