- Learn the general definition of a refractive error.
- Discover the root cause of refractive errors of the eye.
❓ Frequently Asked Questions
Q: What is a refractive error?
A: A refractive error occurs when the eye cannot focus light properly on the retina, resulting in blurry vision.
Q: What are the common types of refractive errors?
A: Common types include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Q: How are refractive errors corrected?
A: Refractive errors can be corrected with eyeglasses, contact lenses, or refractive surgery.
Q: What causes refractive errors?
A: Refractive errors are often caused by the shape of the eye, the cornea, or the lens.
Q: Can refractive errors get worse over time?
A: Yes, some refractive errors, especially myopia, can progress over time, particularly in childhood and adolescence.
