How are concave and convex lenses different?
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
Why do convex lenses have shorter focal lengths than thin convex lenses?
The convex lenses are converging lens so when the curvature of the lens increases the focal length will decrease which helps when looking up close. A thin convex lens is for seeing things from a distant.
Which type of lens magnifies convex or concave?
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 bigger. A concave mirror can magnify. Convex mirrors always shrinks things. They are used sometimes in offside rear vision mirrors for vehicles. A concave mirror will also shrink things if you look at the mirror from far enough away and the object you look at is also far away (but you wouldn't want to use it for a rear vision mirror because it then also turns stuff upside down). Concave lenses disperse light rays outward, rendering it impossible for them to focus incoming light onto a plane surface. Their "focus" is virtual, behind the lens on the side of the light source. If the concave surface is used as a reflector, it will form a real image. This is the basis for reflector telescopes. Further info: http://en.wikipedia.org/wiki/Lens_(optics)
Why is convex mirrors used in vehicles?
convex mirrors are used in vehicles because convex mirrors make things look bigger which will be easy for the drivers.
Does concave mirror make things bigger or smaller and can you see less or more?
Because of it's shape a concave lens bends or refracts light outward away from the center of the lens and towards its thicker edges. The light rays never cross or meet a focal point so the image never inverts. A concave lens makes objects appear smaller than they really are.

What type of lens use in microscope?
Most lenses used to view smaller things is a convex: Telescope, microscope, binoculars, etc.
Does a convex help you see nearby objects?
yes convex lenses help make everything larger which are used for people that are far sighted and concave lenses help make things look smaller and those are used for people that are far sighted

How do people use lenses to see things a long way away?
Lenses are either concave or convex. Concave lenses curve inward from both sides, and convex lenses curve outward one side and inward on the other. Concave and convex lenses change the image to be able to see from close or far distances.These are used for glasses, magnifying glasses, and telescopes.
Which lens is used by dentist?
Well, It depends what kind of image do they want. It would be most likely a convex lens/ mirror. Convex lenses make things bigger.
What things use convex lenses?
You know those microscopes? Well, you probably do. A convex lens can be found in a microscope. Concave AND convex are both used in this item. You can also check www.brainpop.com on microscopes depending on your age (3-5 grades). It sadly cost money. There are also farsightedness glasses that use convex lenses. And you might've guessed, nearsightedness glasses use concave. Magnifying glasses are of convex lens use, too. Then there's also contact lenses. Magnifying glasses, telescopes, vehicle mirrors and more mirrors in hospitals and other building use these lenses. Sorry if this paragraph was too long but I hope this was helpful!
How does a convex lens work to make you see things?
The amount of curve (convex) in the lens determines the strength of the lens, thereby determining the effectiveness (or strength) of the lens. This is how the prescription strength of contact lenses is determined.
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.

Why are concave mirrors suitable for makeup?
Concave mirrors magnify what is viewed in them. That is similar to how convex lenses work (things work opposite with mirrors). So you get a closeup view of your face while you apply makeup.
What did the romans discover as thy experimented with different shapes pf clear glass lenses?
it can help them see smaller things in ore detail
