1. What are refractive errors?
*Answer√√ Focusing problems that occur when light entering the eye does not focus correctly on the
retina.
2. What is myopia?
*Answer√√ Nearsightedness where light focuses in front of the retina, causing distant objects to appear
blurry.
3. What is hyperopia?
*Answer√√ Farsightedness where light focuses behind the retina, making close objects diflcult to see.
4. What is astigmatism?
*Answer√√ Irregular corneal curvature that causes distorted or blurred vision at all distances.
5. What are expected findings for refractive errors?
*Answer√√ Blurred vision at specific distances, eye strain, or headaches from squinting.
6. What nursing interventions are recommended for refractive errors?
*Answer√√ Encourage routine eye exams, ensure corrective lenses are available, and assess safety
concerns.

*Answer√√ Aging, diabetes, smoking, chronic corticosteroid use, excessive UV exposure, eye trauma,
