The main object is the telescope so that it is an easier way to see small things up close.
Magnifying glass is used with this lens
A biconvex lens.
convex
A convex lens is curved on one side and flat on the other, while a biconvex lens is curved on both sides. Biconvex lenses have the same curvature on both sides, which makes them symmetrical, while convex lenses have one flat side. Both lenses converge light rays, but biconvex lenses are thicker in the middle than at the edges.
The biconvex transparent structure that focuses light on the retina is the lens of the eye. It helps to refract light rays and focus them on the retina at the back of the eye, allowing for clear vision.

A magnifying glass typically has a biconvex lens, which is curved on both sides to magnify objects when they are brought closer to the lens. This type of lens allows the light passing through it to converge and create a magnified image of the object being viewed.
A biconvex lens is used to converge light rays to a single point, creating a real image. It is commonly used in magnifying glasses, cameras, and projectors to focus and magnify images.
A biconvex lens is a lens with both sides curved outward, resulting in a convex shape on both sides. This type of lens is thicker in the middle than at the edges, and it converges light rays to a focal point. Biconvex lenses are commonly used in magnifying glasses and camera lenses.
The lens in a cows eye is flexible and clear. The flexible lens is able to change shape which allows it to better focus on objects.
There are many options. Some examples:hemisphere,biconvex lens,finite cone.
