Myopia commonly presents in school aged children, or teenagers, and progression often continues until the late 20’s.
Myopia is prevalent during this time as this is when children’s bodies are growing. Like any part of the body, the eye also needs to grow for full development. However, if the eye continues to grow longer than it needs too, we see myopia form. The longer the eye grows, the higher the prescription needed in corrective glasses, the thicker the lens and the poorer the visual potential.
Why the eye continues to grow, is not fully understood, but we are aware of some risk factors that may contribute which include:
- Increased time indoors, especially on close work and at a younger age.
- Strong family history, approximately 1 in 3 chance if 1 parent is myopic and 2 in 3 chance if 2 parents are myopic.
- Asian ethnicity.
- Academically focused.
