Refractive errors occur when the shape of your eye keeps light from focusing correctly on your retina a light-sensitive layer of tissue in the back of your eye. Myopia, or nearsightedness, is a condition where things that are far are harder to see. In other words, distant objects appear blurry until they are brought close to the eyes.
In the U. Farsightedness, also referred to as hyperopia, is a condition where things that are near are harder to see compared to things that are a further distance away. Astigmatism is a condition in which the cornea has an abnormal curvature that can create two focal points to point in two different locations.
Both nearsightedness and farsightedness are refractive conditions, referring to how light is focused in relation to the eye. Below, learn what farsightedness and nearsightedness mean, as well as the differences between the two. The technical term for farsightedness is hyperopia.
If you are farsighted, you can see distant objects well, but reading or looking at items close up is blurry for you. With hyperopia, the eyeball is either too short or there is not enough curvature of the lens for objects to focus properly. Refractive error means that there is an abnormal shape or size to the eye that makes it difficult for the retina of the eye to focus light.
The official name for nearsightedness is myopia. Myopia happens when the eyeball is too long. Because the eyeball is longer than normal, light cannot focus properly through the lens and cornea. When you view an object, the light rays that hit your eye will end up focusing at a point in front of the retina instead of focusing directly at the retina. This is why objects farther away become more blurry compared to objects up close. The focusing distance is further.
Nearsightedness can also be caused by the curvature of the lens of the eye. If the lens is too curved, this will throw off your focusing point as well. Your risk for myopia increases slightly if others in your family have it, as there is a genetic element that is a factor. Farsightedness is the opposite of nearsightedness.
Objects farther away are seen clearly, while objects up close are blurry. The official term for farsightedness is hyperopia. Both myopia and hyperopia have to do with how light focuses on the eye and where. With hyperopia, the eyeball is either too short or there is not enough curvature of the lens for objects to focus properly.
Light will focus at a point beyond the retina instead of in front of the retina or directly on its surface. This causes blurry vision up close.
Hyperopia is less common than myopia. It is also much harder to detect common vision screenings such as those conducted by schools. There are many problems that could go wrong with the eyes.
You can have perfect vision all of your life and suddenly your vision begins to change. This is common with age, especially once our patients reach 40 or 60, as these are common times for visual changes. The good news is that many eye problems are treatable and even correctable. Nearsightedness and farsightedness are two of the most common problems we encounter in our office. Many patients with these conditions can easily fix the problem with corrective lenses or glasses.

You may be nearsighted. This can happen when each of your eyes develops its own condition. Nearsightedness is the ability to clearly see objects that are close to you but have difficulty seeing objects that are far away. Our eyes help us see by converting light into images.
When light hits our eyes, it travels from the cornea through the pupil and all the way back to the retina. The retina is responsible for passing the light off to the optic nerve, which sends electrical impulses to the brain. Refractive errors have to do with the shape of your eye. You can be born with a cornea that is too rounded or an eyeball that is too long, or you could develop these new shapes as you age and grow.
According to the American Refractive Surgery Council , myopia can be attributed to environmental issues like the use of computers, mobile phones, and electronic readers.
The main symptom of nearsightedness is noticing blurriness when trying to see objects in the distance. For example, having difficulty reading signs while driving, or troubles seeing handwriting on a whiteboard at school. Because of the strain associated with forcing your eyes to focus throughout the day, you might notice these additional symptoms:. Most diagnoses of myopia are in younger children since their eyes change shape as they grow. It is typical for adults to remain nearsighted if they were diagnosed as a child.
According to the American Optometric Association , adults can also become nearsighted due to visual stress or health conditions like diabetes. A diagnosis of myopia can cover a large range. Farsightedness, also called hyperopia, means that you can clearly see objects far away but have difficulty seeing closer objects clearly. Farsightedness is also based on the shape of the eye.
The cornea and lens are the parts of the eye that refract incoming light into the retina. Once the retina receives the light, it passes it off to the optic nerve which carries the information to the brain.
