Concave Versus Convex Lenses. Concave lenses and convex lenses are often used together. Concave lens, when combined with the convex lenses, give sharper images.most eyeglass lenses have combinations of concave and convex. Rays going through a convex lens converge.

Still confused, maybe this will help. A negative meniscus lens has a steeper concave surface and will be thinner at the centre than at the periphery. A convex lens focuses light rays, whereas a concave lens causes the light rays to diverge.

It refracts light outward from the lens. Concave lens, when combined with the convex lenses, give sharper images.most eyeglass lenses have combinations of concave and convex. There are two types of lenses which rare known as convex lens and concave lens. More free physics video lessons. If the object is out of focus of the lens, it will be enlarged or reduced according to the distance from the lens. A convex lens focuses light rays, whereas a concave lens causes the light rays to diverge. This diverged ray strikes convex surface and the converges, thereby finally leading to convergence. Due to the law of refraction, light rays bend as they enter and leave the lens.
