1. What Is Myopia
A short-sighted eye is longer than normal. Light rays focus in front of the retina rather than on the retina. Myopia often progresses throughout the teenage years, when the body is growing rapidly. The main symptom is difficulty in seeing distant objects clearly.
Causes of Myopia
- Genetic Factor
- Environment: Performed the most amount of near work
- In Asia, especially in Hong Kong, children have a higher amount of myopia (because Asian children have more homework)
