The main difference between Myopia and Hypermetropia: Myopia is a refractive error where the eye focuses light in front of the retina, making distant objects appear blurry, while hypermetropia is when light fo
Myopia vs Hypermetropia — Comparison Table
| Basis | Myopia | Hypermetropia |
|---|---|---|
| Definition | Inability to see distant objects clearly | Inability to see near objects clearly |
| Also Known As | Short-sightedness or near-sightedness | Long-sightedness or far-sightedness |
| Cause | Eyeball too long or cornea too curved | Eyeball too short or cornea too flat |
| Image Focus | Light focuses in front of retina | Light focuses behind retina |
| Correction | Concave lens (negative power) required | Convex lens (positive power) required |
| Prevalence in Children | More common in children | More common in older people |
Key Points
- Myopia occurs when the eyeball is elongated or the cornea is too curved, focusing light ahead of the retina
- Hypermetropia occurs when the eyeball is shortened or the cornea is too flat, focusing light behind the retina
- Both conditions can be corrected with appropriate lenses or refractive surgery
- The power of corrective lenses is measured in diopters (D) and depends on the degree of refractive error
