So, what is the principle of myopia correction? First of all, we need to understand that myopia is caused by the eyeball being too long or the refraction being too strong, which leads to inaccurate focus of the eye and the focus falls in front of the retina.
If you want to see things clearly, you need to add a "lens" in front to ensure accurate focus.
Frame glasses are the "lenses" added to this optical system (a concave lens is added for myopia). They can change the light and focus it on the retina, which is how frame glasses correct myopia. Among the many correction methods, frame glasses are the most common correction method because they are easy to obtain, relatively safe, easy to replace, and most acceptable to consumers.
