Why are convex and concave lenses used in photography?
Learn how concave lenses are used in glasses, lasers, cameras, flashlights and peepholes. A concave lens is a negative lens that diverges light rays and forms an upright and smaller image.
- Flashlights. In flashlights, the aim is to project the light on a wider area as possible. The light produced by the bulb is diverged by the concave lens producing a wider beam of light.
- Binoculars. Binoculars enable us to view a magnified image of far-off objects and make them appear closer to us. They are made up of a combination of convex and concave lenses is used.
- Telescope. Telescopes work on the same principle as binoculars. Telescopes are used to view very far-off objects like planets in the solar system. They are also made up of a combination of convex and concave lenses.
- Camera. Cameras use a combination of convex and concave lenses for image formation. The concave lens alone will diffract light into different directions, so it is used in combination with a convex lens.

A concave lens is one that is thicker at the edges and thinner in the centre. This type of lens bends light rays outwards. A concave lens is also known as a diverging lens as it diverges the light rays. It is made up of a number of prisms, with the base of each prism pointing away from the lens's centre. The lens's central section is a simple paral...
The following are the different types of concave lenses: 1. Double concave 2. Plano concave 3. Convexo-concave
To know which type of image is created by a concave lens, the lens formula of that concave lens is used. It is also used to identify the position of the image. The formula for the concave lens is as follows: 1/f=1/v +1/u Where, 'f' = the focal length 'v' = distance of the image. 'u' = distance of the object.
We find the application of concave lens in treating vision issues and for that, we find the uses of a concave lens in daily life; let’s understand how: A concave lens is used to treat myopia because the lens diverges the parallel light rays coming from distant objects. Therefore, a virtual image forms at a distant point of the myopic eye. Now, that...
A person who can view far objects clearly, but when it comes to viewing nearby objects, he/she fails to get a clear vision; let us understand what is the use of convex lenses here? If a person is hypermetropic, the image of a nearby object forms behind the retina. This means that light is focused too far back in the eye that causes things that are ...
So, we will first start with the uses of concave lens Class 10: We find many uses of a concave lens in daily life, the first two uses of the concave lens are: 1. We Find the Use of Concave Lenses in Car Headlights. A concave lens works as a safety factor for driving at night. This lens diverges the light to far distances that help in a clear view o...
In cameras, we find the uses of a concave and convex lens to get clear images in photography. To ameliorate the quality of photographs, camera manufacturers use combinations of convex and concave lenses. Here, a convex lens is used as the primary lens of a camera that causes distortions in the photos, which is called chromatic aberrations. Combinin...
