Myopia, commonly known as nearsightedness, is a refractive error that affects millions of people worldwide. It occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of on it. This results in blurry distance vision, while close-up objects remain clear.
Myopia is measured in diopters, with negative numbers indicating nearsightedness. A person with negative 4 vision has a refractive error of -4.00 diopters, which is considered moderate to high myopia. This means that they can see objects clearly up to about 6 inches away, but anything beyond that distance appears blurry.
What Are the Symptoms of Negative 4 Vision?
- Blurred distance vision
- Squinting to see faraway objects
- Headaches or eye strain
- Difficulty seeing at night
- Increased sensitivity to glare
If you experience any of these symptoms, it’s important to schedule an eye exam with an ophthalmologist. They can determine the severity of your myopia and recommend the best course of treatment.
