## Core Concept
Hypermetropia, also known as hyperopia or long-sightedness, is a refractive error where distant objects are seen more clearly than objects near at hand. This condition occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina instead of directly on it.

## Why the Correct Answer is Right
The correct answer, , implies that in hypermetropia, the focal length of the eye is too long for the given eyeball length, or the eyeball is too short for the given focal length, leading to the focus of light rays behind the retina. This results in close objects appearing blurry.

## Why Each Wrong Option is Incorrect
* **Option A:** Typically, in hypermetropia, the axial length of the eyeball is shorter than normal, or the refractive power of the eye is too low. This matches the definition, so it seems like a correct statement about hypermetropia.
* **Option B:** This option might relate to the type of vision correction needed for hypermetropia, which often involves converging light rays more before they hit the retina, achieved with convex lenses.
* **Option C:** This could relate to a method of correcting hypermetropia, such as using glasses or contact lenses with a positive power to converge light rays earlier.
* **Option D:** The statement here directly contradicts basic principles of hypermetropia if it suggests characteristics not typical of hypermetropia or implies myopia (nearsightedness).

## Clinical Pearl / High-Yield Fact
A key point to remember is that hypermetropia can be corrected with **convex lenses** which converge light rays before they enter the eye, allowing proper focusing on the retina. Young children with hypermetropia might not complain of symptoms because their **accommodative power** can often compensate for the refractive error.

**Correct Answer: D.**
