WebAug 6, 2024 · Farsightedness (hyperopia) is a condition in which you can see far objects clearly, but nearby objects are blurry. When you have a shorter than average eyeball or a cornea that is too flat, light focuses behind the retina instead of on it. This blurs near vision and sometimes distant vision. Astigmatism causes overall blurry vision. WebJan 20, 2024 · Myopia vs. Hyperopia. Myopia and hyperopia are common — but essentially opposite — types of vision problems. The biggest difference between them is where objects appear in focus. People with myopia …

The biggest change in the refractive index, and bending of rays, occurs at the cornea rather than the lens.
