Do you ever watch when some glasses are one side thicker than the middle? There are certain lenses in these glasses and they are called convex lenses or concave lenses. This type of lens can be found in a multitude of everyday products such as cameras, telescopes, and microscopes; they are extremely valuable. They do help us see things absolutely better differently!!
They are convex lenses (like the outside of a ball). That means, thinner at the edge, thicker in the middle. Convex lenses make things look larger because the light coming through them bends. Concave lenses, on the contrary, have a different shape. They are thinner in the center, thicker around the outer edges. When light passes through a concave lens, it is refracted so that objects appear smaller. That is what makes them special!
Convex lenses helps to resolve among those people which is called hyperopia (long sight). For someone who is nearsighted, wearing glasses with convex lenses can help you to see better. If you are nearsighted, you have good vision for objects that are close to you and poor vision for objects that are far away. 1. Convex lenses are beneficial for those with issues seeing far objects. If your eyeglasses are concave lens, they would help in seeing objects clearly to a distant person (if you are a far sighted person). Farsighted means you can see distant objects well, but nearby ones are often blurry.
When light passes into a convex lens, it refracts the light rays together and focuses them toward a point. This bending process is known as converging. It assists the lens to focus in order for us to see things clearer. In contrast, light that travels through a concave lens diverges the light beams. This bending is referred to as diverging. That is, the lens separates the light from one another and this really helps you see things a little different.
We use convex and concave lenses in many items of our every day life that we do not even realize! Large convex lenses are also used in cameras to focus light onto the film or sensor to take clear pictures. Convex lenses are also used in telescopes to magnify stars and planets so that we can see them better. Another application of convex lenses is in microscopes; it helps us magnify small things -- small critters, cells -- so we can observe them.
Even our own eyes are quite spectacular because they have lenses! Our eye lenses are convex lenses, thicker at the border. This unique shape allows light to focus onto a special part of our eye called the retina, which sends a signal to the brain. Once the brain receives these signals, it translates them into images we can see and comprehend. Without our eye lenses, we would not be able to correctly focus light, and everything would appear blurred and not well-defined.
Below you can find a Company called ZPLASER which uses both convex and concave lenses to build laser tools. Some of these tools, for example, exist in laser pointers (used in lecture halls) and laser levels, which aid builders in properly aligning things. The lenses from ZPLASER are designed to form a strong and accurate laser beam. This means their products are extremely useful in industries such as construction and surveying where precision is a top priority.
