Myopia, also known as nearsightedness, means that you can see objects clearly when they are close to you, but distant objects appear blurry.
In more detail:
Myopia is a common refractive error affecting how the eye focuses light. This occurs when the shape of the eye, or parts within it, causes light rays to bend (refract) incorrectly. Instead of focusing light precisely on the retina (the light-sensitive tissue at the back of the eye), the light focuses in front of the retina. This causes faraway objects to appear out of focus.
Here's a breakdown:
- Clear Close Vision: Individuals with myopia can typically see near objects without difficulty.
- Blurry Distance Vision: The primary characteristic of myopia is difficulty seeing objects at a distance clearly.
- Cause: Myopia is often caused by the eyeball being too long from front to back, or the cornea (the clear front surface of the eye) being too curved. These conditions cause light to focus incorrectly.
Key takeaways:
- Myopia is another term for nearsightedness.
- It results in clear close-up vision and blurry distance vision.
- It is caused by the eye focusing light in front of the retina instead of directly on it.
