What is Myopia?
- Myopia is the medical term for ‘nearsightedness’.
- In a myopic eye, near objects such as a book may be seen clearly, however, distant objects appear blurred.
- Having an eyeball that is too long or a cornea that has too much curvature are usually the reasons for myopia.
- The excess length or curvature causes light entering the eye to focus in front of the retina, which causes the distance blur.
What are the Symptoms of Myopia?
- Blurred distance vision
- Excessive squinting
How Common is Myopia?
- Being nearsighted is very common in the United States.
- Nearly 25-30% of the population is myopic
- Certain groups of people are more at risk for myopia due to genetics or lifestyles
- People with myopic parents, Asian-Americans and people working in jobs that involve a lot of reading tend to be myopic more often
What Causes Myopia?
- Most myopia is genetic, meaning you inherit it from mom and dad
- Some evidence points to excessive near work and the stress that causes on the eye as a potential cause of myopia as well.
- People who spend a lot of their time reading or those who work extensively on computers tend to be at higher risk for myopia development
