The magnification of an image when observed by the eye is the angular magnification M, which is defined by the ratio of the angle \(θ_{image}\) subtended by the image to the angle \(θ_{object}\) subtended by the object.

(a) With no convex lens, the object subtends an angle \(θ_{object}\) from the eye. (b) With the convex lens in place, the image produced by the convex lens subtends an angle \(θ_{image}\) from the eye, with \(θ_{image}> θ_{object}\).

Telescopes gather far more light than the eye, allowing dim objects to be observed with greater magnification and better resolution.
