Convex lens could be used for the cornea to see better it could also be used on cameras to make an image more clear and even improve an image.
When you see through a concave lens you see a magnified view of what you wish to see
See the link below for the formula of lens power.
A concave lens helps you see far if you're nearsighted and convex lenses help you see near if you're farsighted.

no. its lens like glass for you to see far or near
The first telescope was used by Galileo Galilei (first used in 1609) to see the faraway planets and stars of the galaxy.
You use it to magnify an object.You can not see it with your naked eye.
A 1300mm lens can see to infinity.
Helps to refract light to be focused on the retina.

the lens in the eye is used to focus.when it becomes opaque youcant see anything.for example specs help you see better but if they are replaced by two pieces of circular cardboard you cant see anything.if you get a cataract the lens has to be replaced by an artificial intraocular lens.
A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. A hand lens can be used to magnify an object to make it easier to see or also to focus light.

There are many factors that contribute to human sight. The lens is used to refract light to be focused on the retina (allowing you to see). It's similar to a camera lens. Removing the lens would be detrimental to eyesight and the eye would not definitely not work properly. As for being able to see ever again, there are surgeries that can correct almost every part of the eye, including the lens. So it's possible to see again, just not very likely without the help of the lens to refract light onto the cornea.
echo location is where you can hear from faraway in a certain location
