Myopia vs. Hyperopia: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on August 19, 2024
Myopia, or nearsightedness, is difficulty seeing distant objects; hyperopia, or farsightedness, is trouble seeing close objects.
Key Differences
Myopia and hyperopia are two common refractive errors of the eye, each resulting in different visual impairments. In myopia, often referred to as nearsightedness, distant objects appear blurry while close objects can be seen more clearly. Conversely, in hyperopia, or farsightedness, close objects appear blurry while distant objects might be clearer. These conditions arise due to the way light rays are bent or refracted as they enter the eye and focus on the retina.
The physical structure of the eyeball plays a significant role in determining whether an individual has myopia or hyperopia. In the case of myopia, the eyeball is typically longer than usual, or the cornea has an excessive curvature. This causes light rays to focus in front of the retina instead of on it. On the other hand, hyperopia is often caused by a shorter than average eyeball or a flatter cornea. In this scenario, light focuses behind the retina, making it difficult to see nearby objects distinctly.
Both myopia and hyperopia can be present from birth, but they can also develop or change over time. Myopia often starts in childhood and may continue to increase until the individual reaches young adulthood. It's not uncommon for school-age children to develop myopia if they engage in extensive close-up activities like reading or using computers. Hyperopia, while also present in some children, often becomes more noticeable in adults over the age of 40, when the ability to focus on close objects diminishes, a condition called presbyopia.
To correct the vision problems caused by myopia and hyperopia, various optical solutions are available. Myopia is usually corrected using concave lenses, which help to spread out light rays, ensuring they focus on the retina. For hyperopia, convex lenses are employed to converge the light rays and shift the focal point forward onto the retina. Whether it's through eyeglasses, contact lenses, or surgical interventions, both conditions are treatable, and individuals can achieve clearer vision.
Regular eye examinations are crucial for detecting and managing conditions like myopia and hyperopia. While both conditions manifest with blurriness at different distances, other symptoms like eyestrain, headaches, or the need to squint might also be indications of these refractive errors. Early detection of myopia or hyperopia can lead to more effective interventions, ensuring better visual health and quality of life for affected individuals.

Myopia and Hyperopia Definitions
Myopia
A vision condition causing distant objects to appear blurry.
Her myopia made it hard to see the board at school.
Hyperopia
A vision condition causing difficulty seeing close objects clearly.
His hyperopia made reading small print a challenge.
Myopia
Caused by an elongated eyeball or excessive curvature of the cornea.
Myopia in her case was due to a longer-than-average eyeball.
Hyperopia
Light rays focus behind the retina.
Her hyperopia caused images to focus beyond the retina.
Myopia
Correctable with glasses, contact lenses, or refractive surgery.
He used glasses to correct his myopia.
Hyperopia
Can be corrected with glasses, contact lenses, or refractive surgery.
She chose contact lenses to correct her hyperopia.
Myopia
Also known as nearsightedness.
With myopia, he couldn't see the street signs clearly.
Hyperopia
Also known as farsightedness.
Due to her hyperopia, she needed reading glasses.
Myopia
Light rays focus in front of the retina.
In her myopia, images focused before reaching the retina.
Hyperopia
Results from a shorter eyeball or a cornea with too little curvature.
Hyperopia in his case was attributed to a flatter cornea.
Myopia
A visual defect in which distant objects appear blurred because their images are focused in front of the retina rather than on it. Also called nearsightedness, short sight.
Hyperopia
An abnormal condition of the eye in which vision is better for distant objects than for near objects. It results from the eyeball being too short from front to back, causing images to be focused behind the retina. Also called farsightedness, hypermetropia.
Hyperopia
(pathology) A disorder of the vision where the eye focusses images behind the retina instead of on it, so that distant objects can be seen better than near objects.
Hyperopia
An abnormal condition of the eye in which, through shortness of the eyeball or fault of the refractive media, the rays of light come to a focus behind the retina, making vision for distant objects better than for near objects; farsightedness; - called also hypermetropia. Cf. Emmetropia.
Hyperopia
Abnormal condition in which vision for distant objects is better than for near objects
