Larger in diameter. The human eye can open to a maximum of about 7mm. Calculate the area of that, and compare it with a 50 diamter mm lens. (A=pi*r^2). Where 3.5 = radius of the pupil and: 25 = radius of the lens pi * 3.5^2 mm = 21.99 mm ^2 (area of a pupil in the dark) pi* 25^2mm = 1963.5 mm^2
Therefore, a 50 mm lens would have 89.29 more light grasp than the eye.

What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
Does a reflecting telescope gather light with a lens or a mirror?
reflecting telescope gathers light from mirror
What is meant by the size of a telescope?
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.
Compare the functions of the objective lens in a telescope and a microscope?
The objective lens in a microscope is mainly used to magnify an object. In a telescope, the objective lens is mainly used to gather light.
Which type of telescope uses a mirror to gather light?

What telescope doesn't use mirrors or lenses to gather light?
A radio telescope.
