When a person is far sided do the need a concave lens or convex lens?
Farsighted people use convex lenses to correct their vision.(This is the correct answer!)
Why use convex lens?
convex lenses are for short sighted people.
What is the difference between a concave and convex lens?
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
What lens used to correct nearsightedness?
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.
What uses concave lens?
Glasses for short sighted people.
What kind of lenses would a farsighted person need to correct their vision?
Hyperopic, plus powered, or convex lenses.
What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
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

Why are convex lens useful?
convex lenses are for short sighted people.
Why use convex lens?
convex lenses are for short sighted people.
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.

What are the uses of concave lenses?
Uses of concave mirrors are:1) They are used in telescopes.2)They are used as dentists' mirrrors to magnify the image of a patients teeth to faciliate the examination.3)They are used as cosmetic mirrors to have an enlarged view of the face to apply make up or to shave.4) A Car Headlight bulb has a convex mirror.5)Make-up mirrors in department stores make you look skinnier than you really are.6.) Used as source of fire.7.)They are useful in projector lamps.
What do the lens do in the eye to help us see?
the lenses make objects look smaller than what they are so that people know what they look like.
