Myopia is the medical term for the condition known as nearsightedness. As the name implies, people who are nearsighted can easily see objects that are near to them, but struggle with objects that are far away. Myopia affects people from all walks of life and of all ages.
What causes myopia?
Nearsightedness itself is caused by a refractive error in the eyes. This refers to the refraction of light that is the cornerstone of healthy vision. In a case of myopia, the light that would normally be focused on the retina directly, instead lands in front it.
It isn’t currently known why some people develop myopia and others do not. However, certain risk factors increase a person’s likeliness of being nearsighted:
Family history
Heavy amounts of up-close reading or work over a lifetime
What are the symptoms of myopia?
Common symptoms of myopia include:
Blurry vision
Headaches from eyestrain
Frequent squinting
Double vision
Trouble seeing at night
Difficulty driving or navigating
Treating myopia
Myopia is very treatable, with nearly every person diagnosed with the condition receiving a measurable improvement in vision. Common types of myopia treatment include:
Prescription eyeglasses
Contact Lenses
LASIK Surgery
Refractive Eye Surgery
Intraocular lens implants (IOLs)
HYPEROPIA
Hyperopia is the medical term for the common eye condition known as farsightedness. Those who deal with hyperopia have difficulty seeing things that are near to them, but have better vision for objects that are far away.
What causes hyperopia?
The actual farsightedness associated with hyperopia stems from a refractive error in the eye. In a healthy eye, the lens and cornea bend light evenly, providing clear vision. This is known as refraction. When suffering from hyperopia, however, the lens or cornea is out of place or insufficiently curved, leading to reduced vision quality.
For most people, the cause of hyperopia is genetic - the condition is usually inherited. Scientifically, it is not currently known why some families suffer from farsightedness and others do not.
What are the symptoms of hyperopia?
People who are farsighted typically have symptoms such as:
Blurry vision
Squinting
Eyestrain
Itchy, burning eyes
Treating hyperopia
Farsightedness is one of the most common eye-health problems in the world. Because of that, many treatment options are available.
