What is the diff of concave and convex lens?
A concave lens is thinner at the center than at the edges and causes light rays to diverge. This lens is used for correcting short-sightedness. In contrast, a convex lens is thicker at the center than at the edges and causes light rays to converge. This lens is commonly used in magnifying glasses and camera lenses.
What is the property of image formed by concave lens?
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
Should a short sighted person use a concave or convex lens?
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 .
What is the thick lens equation used for in optics?
The thick lens equation is used in optics to calculate the focal length of a lens that is not thin, taking into account the thickness of the lens itself.
What is nature of concave lens?
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 :)

According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
What ocular lens is used for near sight?
The ocular lens used for nearsightedness is known as a diverging lens. It is also known as a concave lens.
Where can one go to have contact lens implants?
One can go to Optimax for treatment for contact lens implants. This is for the severe levels of short sight and long sight. It replaces the natural eye lens with contact lens. Optimax does a great treatment.

Why does the eyes become smaller when you wear glasses?
This happens when you wear a concave lens for curing short sight. If you wear convex lens in case of long sight, then eyes would look bigger than the original. Both are so dominant if the power is high. If we wear low power glasses then no such considerable change in the size of the eyes.
