There are many uses of diverging lenses including being used as a microscope lens. The main use is to correct short sightedness.
This is a lens which is designed to help someone who has problems seeing at distance (myope), the light rays going into your eye are not hitting the fovea (the part of the eye located on the retina which allow you to see clearly) in the proper place, these rays are falling in front of the fovea, so by using a concave ( a minus lens) lens, this moves these light rays by diverging them and moving them back to the fovea which allows for clear vision at distance. At least this is how a concave lens is used optically speaking.this is from winter006: concave mirrors are used in stores and gas stations to see a wider area of the store.It's also called , a Diverging Lens .It is thinnest in the centre and spreads light out , so it gives a diminished image .
Both give diminished, virtual, erect image. Hence convex mirror is used as rear view glass in case of vehicles near by the drivers. Concave lens is used to correct short sightedness.
Lens that possesses at least one surface that curves inwards. It is a diverging lens, spreading out those light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness. Hope this helps you :)
Convex lenses are thicker in the middle then the edges and concave are thicker at the edges then the middle. When light travels through lenses, refraction occurs. The light bends either outward or inward, it depends on the lens.The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina. These people see far but have some difficultly seeing close-up.To correct this farsightedness, the person would wear glasses or contacts with convex lenses, for It is often used for close examination of small objects.

It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.It can be used for treating epilepsy, however it is generally not used as a long term treatment for it because people can become resistant to its effects in treating seizures.
Uses of Concave LensesConcave lenses are used to make objects look smaller.
Convex lenses, which magnify, correct hyperopia. Below, is a previous wiki answer to this question in detail.Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia).Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia).A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look biggeRead more: Which_type_of_lens_magnifies_-_convex_or_concave

Short sightedness (or myopia) occurs when the eye focusses the image in front of the retina. A minus powered lens is used to bring the image forward and so into focus.It is easily correctable with glasses, contact lenses or laser surgery.

A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia). The writings of Pliny the Elder (23-79) makes mention of what is arguably the earliest use of a corrective lens. According to Pliny, Emperor Nero was said to watch gladiatorial games using an emerald, presumably concave shaped to correct for myopia.
