WebbConvex Lenses. When an object is placed at infinity, the real image is formed at the focus. The size of the image is highly diminished and point size. When an object is placed beyond the centre of curvature, the real image is formed between the centre of curvature and focus. The image size will not be the same as the object. WebbLike other lenses for vision correction, aspheric lenses can be categorized as convex or concave.
