Study Notes
Refractive Errors
- Astigmatism is a refractive error caused by an irregularly shaped cornea.
- The eye part affected by refractive errors is the cornea and lens.
- Farsightedness (hyperopia) is a refractive error where close objects appear blurry.
- The medical term for farsightedness is hyperopia.
- Farsightedness is caused by the eyeball being too short or the cornea being too flat.
- The main symptom of farsightedness is difficulty seeing close objects clearly.
Eye Function
- The retina is responsible for converting light into electrical signals sent to the brain for interpretation.
