Nearsightness is when you can only see up close and not far away. Farsightness is when you can only see far away and not up close. =)
Nearsightedness is when you can only see far and farsightedness is when you can only see close.
Nearsightedness is called Myopia and farsightedness is called Hyeropia.
-They both require glasses -They both have weak eyes
Nearsightedness, also known as myopia, is more common than farsightedness, also known as hyperopia.
It is nearsightedness and hyperopia is farsightedness.
Farsightedness NOT nearsightedness
Sph (sphere) is a measurement of refractive error in eyeglass prescriptions, indicating the amount of nearsightedness or farsightedness. It is measured in diopters. Positive sph values indicate farsightedness, while negative values indicate nearsightedness.
Blurred eyes are caused by nearsightedness, farsightedness and macular degeneration.
Farsightedness is when your vision is good at seeing distances, but needs correction to see clearly the things that are close to you. Nearsightedness is when your vision is good at seeing things that are close to you, but needs correction to see clearly the things that are further away.
An eye doctor would need to measure the distance to the retina to correct nearsightedness or farsightedness. Nearsightedness occurs when the focal point of light falls short of the retina, so the goal is to adjust the focus point onto the retina. Farsightedness happens when the focal point falls beyond the retina, so the focus point needs to be moved closer to the retina.
"Sph" in an eye prescription stands for sphere, which indicates the amount of lens power needed to correct nearsightedness or farsightedness. A negative value indicates nearsightedness, while a positive value indicates farsightedness.
Nearsightedness, farsightedness, and astigmatism can be corrected using LASIK or PRK.
