A magnifying lens
Because the 2cm lens has 4 times the area of a 1cm lens. (area = Pi*r2)
There are a few camera lens types such as : a wide angle lens (used to capture a larger area than the area visible by a human eye), telephoto lens (opposite of wide angle), panoramic lens and so on.
lens cataracts could develop from damage to the lens.
the lens of the eye
The light-gathering power of a lens is proportional to its area, which is determined by the formula for the area of a circle, ( A = \pi r^2 ). A 1-cm diameter lens has a radius of 0.5 cm, giving it an area of ( \pi (0.5)^2 = \frac{\pi}{4} ) cm². In contrast, a 2-cm diameter lens has a radius of 1 cm, resulting in an area of ( \pi (1)^2 = \pi ) cm². Since ( \pi ) is four times ( \frac{\pi}{4} ), the 2-cm lens indeed has four times the light-gathering power of the 1-cm lens.
A convex lens will magnify objects viewed through it, making them appear larger. The lens focuses light rays onto a point, creating an enlarged image. As a result, the area seen through a convex lens will appear larger than the actual object being viewed.
