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 instruments make use of lenses?
We find that imaging equipment that makes tiny things appear big (a microscope) or really far away things appear close (a telescope) uses lenses. There are also new tools that allow looking "into" and "around" things by virtue of fiber optics, and they employ lenses. Industry and medicine have a wide variety of 'scopes to do all kinds of stuff with. Still and moving picture technology still relies on lenses. There are a few more things, lke a simple looking glass, that are or make use of lenses. Oh, and don't forget corrective optics so people can see better. Glasses or contacts are lenses.
Ability to see things clearly near and far away?
The ability to see things clearly near and far away is called visual acuity. This is determined by how well your eyes can focus on objects at different distances. If you have trouble seeing things clearly both up close and at a distance, you may have a refractive error like nearsightedness or farsightedness, which can be corrected with glasses or contact lenses.
How do you change lens in endura shark sunglasses?
I had the same question, so I asked Endura. * With your thumb and forefinger, grasp the frame firmly at the centre of the glasses (above the nose piece). * With the other hand, grasp one of the lenses close to the nose piece between thumb and forefinger. * Pull the lenses downwards firmly away from the frame. They should release with a bit of effort. To insert other lenses, reverse the process... * Align the new lenses to the slot in the frame. * Hold the lens between thumb and forefinger close to the nose piece. * Whilst holding the frame firmly at the centre with the other hand, push the lenses firmly upwards into the frame. It should click into place.

What is the difference between zoom and telephoto lenses?
Zoom lenses have a variable focal length that allows you to change the magnification of the image without physically moving closer or farther away. Telephoto lenses have a fixed focal length that magnifies distant subjects, making them appear closer.
