Myopia is also called near-sightedness and short-sightedness.
Understanding Myopia
Myopia is a common vision condition where light from distant objects focuses in front of, rather than directly on, the retina. This refractive error results in distant objects appearing blurry while close objects usually remain clear.
According to the reference, myopia is precisely known by these other names:
- Near-sightedness: This name reflects that people with myopia can see objects near them clearly.
- Short-sightedness: This name also indicates that vision is clear only for a short distance.
What Causes Myopia?
Myopia typically occurs when the eyeball is too long from front to back, or when the cornea (the clear front surface of the eye) is too steeply curved. These structural differences cause the light entering the eye to focus prematurely.
Common Signs of Myopia
Identifying myopia early is important. Some common signs include:
- Difficulty seeing distant objects clearly (e.g., road signs, the board in school).
- Squinting or partially closing the eyelids to see clearly.
- Headaches caused by eyestrain.
- Difficulty with night driving.
Correcting Myopia
Vision problems like myopia can usually be corrected. Common methods include:
- Eyeglasses: Lenses prescribed to refocus light onto the retina.
- Contact Lenses: Worn directly on the eye to correct focus.
- Refractive Surgery: Procedures like LASIK or PRK that change the shape of the cornea.
These correction methods help ensure that light properly reaches the retina, restoring clear vision for distant objects.
