These refractive errors all occur when light fails to focus properly on the retina. Learn more about how your eyes are affected by these common eye problems.
Can you have both hyperopia and presbyopia?Yes. People who are naturally farsighted will start to notice presbyopia sooner than people who are not farsighted. That's because people with hyperopia really need to work hard to see up close. As presbyopia sets in and their lenses get stiffer, the extra work becomes noticeable very quickly.
What is hyperopia of both eyes with astigmatism?In astigmatism the abnormally curved cornea causes the lighted object to strike the retina in two different spots causing vision blurring for objects close or far away. Hyperopia is caused by distant objects being focused behind the retina making objects up close appear out of focus.
What is the treatment for myopia hyperopia astigmatism and presbyopia?Refractive surgery is an ophthalmological specialty that involves surgically correcting refractive defects, including myopia, hyperopia, astigmatism and presbyopia. Its objective is that patients no longer require glasses or contact lenses, thus improving their quality of life.
