Definitions
- A condition where a person can see nearby objects clearly but has difficulty seeing distant objects. - A type of refractive error that causes light to focus in front of the retina instead of on it. - Also known as nearsightedness.
- A condition where a person's cornea or lens is irregularly shaped, causing blurred vision at all distances. - A type of refractive error that causes light to focus unevenly on the retina. - Can cause distorted or blurry vision, headaches, and eye strain.
List of Similarities
- 1Both are types of refractive errors that affect vision.
- 2Both can be corrected with glasses, contact lenses, or surgery.
- 3Both can cause headaches and eye strain.
- 4Both can affect people of all ages.
What is the difference?
- 1Cause: Myopia is caused by the eyeball being too long or the cornea being too curved, while astigmatism is caused by an irregularly shaped cornea or lens.
- 2Symptoms: Myopia causes difficulty seeing distant objects, while astigmatism causes blurry or distorted vision at all distances.
- 3Treatment: Myopia is typically corrected with concave lenses, while astigmatism is corrected with cylindrical lenses.
- 4Prevalence: Myopia is more common than astigmatism.
- 5Age of onset: Myopia often develops in childhood or adolescence, while astigmatism can develop at any age.
Remember this!
Myopia and astigmatism are both types of refractive errors that affect vision. However, the difference between them is their cause, symptoms, treatment, prevalence, and age of onset. Myopia causes difficulty seeing distant objects and is caused by the eyeball being too long or the cornea being too curved. Astigmatism causes blurry or distorted vision at all distances and is caused by an irregularly shaped cornea or lens.
