Want this question answered?
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
Concave and Convex
You need a type of lens that are called convex lens.
the lenses make objects look smaller than what they are so that people know what they look like.
A concave lens helps you see far if you're nearsighted and convex lenses help you see near if you're farsighted.
Johannes Kepler(1571-1630), suggested in 1611 that using convex lenses within the eye piece and a convex lens in the objective would help improve the image. However, he never attempted to make this microscope.
If you are talking about lenses glasses. They help people see long distance or short
Lenses can help people to see better. Lenses are needed in telescopes for astronomers to see distant things in the night sky.
Progressive Lenses mostly used by for 35-40 age group people Progressive lenses look precisely the same as single vision lenses, but they are no-line multifocal eyeglass lenses. In simple words, progressive lenses are lenses that will help you see clearly at all distances. As people get old, the need for progressive lenses increases. By the age of 35 or 40, usually many people have difficulty focusing their eyes on nearby objects. To resolve this problem, some people wear single-vision eyeglasses for reading and seeing too close objects.
If you are farsighted, meaning that you can see far but you can't see objects close up, that means your eye is too short in terms of the distance of your retina to your lens. The image focuses behind the retina, so it becomes blurry. When you add a convex lens, it will help bend the light more and converge the light rays onto the retina, so you will see the image clearly. If you are nearsighted, your retina is farther away from your lens, so the image is focusing in front of your retina, so you can't see distant objects. That's when you need a concave lens. Concave lens will diverge the light rays onto the retina.
i dunnoo you tell me
The ability to make images bigger is called refraction which bends light. Magnifying glasses help make objects bigger so they use refraction.
