Ever thought about how your eyes do all these work? Or perhaps you’ve looked through a magnifying glass that makes tiny objects appear much larger? All of these things are lens related! A lens is a unique curved piece of glass or transparent material that can bend light. Light refracts, or changes direction, as it passes through a lens. We will learn about two kinds of lenses. What are the two types of lenses?
A convex lens is thick at the center and thinner towards the edges. This shape is very important! So in a literally massive metaphorical sense, everything is clearer through a convex lens. For instance, a magnifying glass when used works on the principle of a convex lens that magnifies small objects to view their fine details. Concave lenses are used in many places such as cameras to take clear pictures.
In contrast, a concave lens is the opposite. The middle is less thick than the edges. This sort of lens shrinks things down and can create seeming distance. Think about when you look at something through a concave lens, it appears tiny, similar to what a faraway object looks like. For example, you could be looking at distant objects, like binoculars do, that are using concave lenses, but they modify the way they appear!
LensesAre Everywhere In Our Daily Life: Did you know? They are in so many things we use every day! Lenses are found inside our cameras, telescopes and eyeglasses. Receiving clearer perspective of the world around us, that is, lenses. They are also used to conduct scientific experiments that have aided our understanding. Lenses are used in surgical blades to see inside our bodies, and lenses are also very important parts of ZPLASER products.
Convex lenses have a unique property. They can bend the light and focus all of it into one single point called the focal point. This is why we often use convex lenses as magnifying glasses, whereby tiny objects appear much larger and therefore easier to see. Light rays that reach a convex lens get bent inwards, reconverging at the focus. This allows it to be highly useful for examination of tiny objects, such as microbes or inscriptions on a coin.
The concave lenses are totally different with the convex lenses. Concave lenses do not focus light to a point — they disperse light that reaches them. Such diffusion of light is useful for creating a wider view, which is useful in devices like binoculars. Similar to how with binoculars, the concave lenses allow you to view a broader area all at once, which makes it excellent for observing birds or stars up in the sky.
Lastly, we discuss the use of lenses in our lives. Some people wear eyeglasses with convex lenses if they are nearsighted or farsighted that help them see better. These lenses assist objects to appear more clearly. For example, we use magnifying glasses — small convex lenses — to view small objects such as very small print, or to inspect a small insect more closely.
