Why is convex lens important?
Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye’s lens and retina is too short, as a result of which the focal point lies behind the retina. Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.
What is convex lens one word?

A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the edges, making the light diverge.
How do you describe a convex lens?
A convex lens is thicker in the middle than it is at the edges. Parallel light rays that enter the lens converge . They come together at a point called the principal focus . In a ray diagram, a convex lens is drawn as a vertical line with outward facing arrows to indicate the shape of the lens.
Is magnifying glass a convex lens?
A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length from the lens.
