Myopia is a condition that affects how clearly we see nearby things, but what causes it and why does a child’s vision seem to get worse over time?
Read on as a Broomfield, CO optometrist talks about myopia in children and why it tends to get worse over time.
Myopia, also known as nearsightedness, is a condition that occurs when the eye grows too long from front to back.
As a child grows, the eyeball naturally lengthens. This is called “axial growth.” In myopia, the eyeball becomes too long from front to back. This causes light to focus in front of the retina instead of directly on it. As a result, distant objects appear blurry. This is also known as a “positive” or “excessive” refractive error.
The term “refractive” refers to how light travels through an object and bends as it enters one side and exits from the other. So in myopia, light bends as it travels through your eye and focuses in front of your retina, causing blurry vision.
Myopia is often diagnosed when children reach school age. It’s usually first detected during a vision screening at school.
Myopia can be caused by many different factors. It’s often inherited, but it can also be caused by a genetic disorder called Marfan syndrome.
