Are the lenses of myopia glasses usually concave or convex? It is a concave lens. When the eye sees distant objects, the light is scattered after passing through the concave lens, dissipating the focus point, so that the collimated light passes through at least the central part of the retina, correcting the symptoms of myopia and making the vision clearer.
