03 3. Comparative Analysis: Comparative Analysis: Myopia vs. Hyperopia Vision Defects
1Vision Capability
Short-Sightedness (Myopia)
- Sees near objects clearly; distant objects blurred
Long-Sightedness (Hyperopia)
- Sees distant objects clearly; near objects blurred
2Anatomical Cause
Short-Sightedness (Myopia)
- Eyeball diameter too long or cornea too convex
Long-Sightedness (Hyperopia)
- Eyeball diameter too short or cornea less convex
3Image Formation Point
Short-Sightedness (Myopia)
- Formed IN FRONT OF the retina
Long-Sightedness (Hyperopia)
- Formed BEHIND the retina
4Corrective Optical Lens
Short-Sightedness (Myopia)
- Concave Lens (Diverges rays onto retina)
Long-Sightedness (Hyperopia)
- Convex Lens (Converges rays onto retina)
