What type of lens is used to correct long sightedness?
Convex lens is used to correct long sightedness (hyperopia). This lens helps to converge the light rays entering the eye, allowing the image to focus correctly on the retina.
Can the same lens be used to correct both short sightedness and long sightedness?
Yes, a lens can be designed to correct both short-sightedness (myopia) and long-sightedness (hyperopia) depending on the specific prescription needed. These types of lenses are called multifocal or progressive lenses, which have different sections to correct vision at different distances.
Why convex lens is used to cure long sightedness?
A convex lens is used to correct long-sightedness (hyperopia) because it helps to converge light rays onto the retina. In hyperopia, the light rays focus behind the retina, causing distant objects to be seen more clearly than close objects. By using a convex lens, the light rays are refracted so that they converge properly on the retina, allowing the individual to see both near and distant objects clearly.
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.
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 a sentence for concave lens?
A Concave lens is used to correct short- sightedness.
What are the uses of diverging lenses?
There are many uses of diverging lenses including being used as a microscope lens. The main use is to correct short sightedness.

Is diazepam used for epilepsy?
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.

What type of lens is used in spectacles to correct long sightedness?
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
What lenses would you use for short sightedness and long sightedness?
For short-sightedness (myopia), concave lenses are used to diverge light before it reaches the eye, helping to focus the image correctly on the retina. For long-sightedness (hyperopia), convex lenses are used to converge light before it reaches the eye, assisting in bringing the image into focus on the retina.
What kind of lens are used to correct near sightedness?
Concave lenses are used to correct nearsightedness (myopia). These lenses are thinner at the center and thicker at the edges, helping diverging light rays to focus properly on the retina and improving distance vision.
Which explains why a short eyeball is the cause of farsightedness?
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.
