It bends them relative to the curve of the lens.

you want to do a ray hint by the lens. Snell's regulation says that a ray of light entering right into a severe index of refraction media from a decrease one, will bend in route of the conventional to the exterior and vice versa for gentle going from severe to low index textile. The geometry of the concave lens is such that the gentle diverges on exiting the lens - again you want to do the ray hint to make sure this obviously or get an optics e book or Google it. A convex lens has a geometry such that the gentle converges to three extent previous the lens upon exiting the lens.

For the opposite reason from my answer to your convex question. The direction of refraction, when entering the lens, is always towards perpendicular to the glass's surface. In this case, the surface is angled so that rays further from the center get greater outward (rather than inward) refraction.

its because they refract light, convex lenses make the light converge...

because it bends the light
