Water, gasses. Any other medium that has a different "n" value gives rise to a bending of light.
some space tools are hammers and scoops
You proberly don't realise it but lenses are used nearly everywhere in our daily lives, and a lot of people rely on them to live a normal life. Without lenses a lot of the universe will be undiscovered. Below are some examples where lenses are used:·Glasses (convex and concave lenses)·Microscopes·Telescopes·Binoculars·Digital Cameras·Video cameras·The movie cinemas·Projectors·Webcams
Carl Zeiss is known for making optical lenses. Meaning he advanced lenses for the microscopes ans made the first compound microscope. To day Carl Zeiss lenses are used in high end Digital cameras, SLR Cameras, Camcorders as well as some Mobile phones.
telescopes
Mirrors don't refract, they reflect. All lenses, on the other hand, refract (bend) the light. All cameras have lenses, to focus the image; same for eyeglasses. Some telescopes have lenses, but others are collections of mirrors. Note that some few optical elements are lenses and mirrors - like prescription sunglasses with mirror coating.
All see-through materials. Glass is well known. Water also refracts light. Diamonds refract light a lot. Even air refracts light a little.
Objects that refract light include lenses, prisms, and water droplets. When light passes through these objects, its path is bent or altered due to the change in medium or the different angles of the surfaces.
Non-corrective lenses do not affect the direction of the rays of light. What they do affect is the composition of the light. Non-corrective lenses are filters blocking out some wavelengths of light in order to do not reach the human eye.

Some kind of lens or a change in a substance: the surface of a pond, through a prism, through glass... all of these may refract light.

Some of the minerals in the meat form chrystals that refract the light like a prism.
Some cheap glasses will have lenses that refract the light to such a degree, like wearing mild prescription glasses. it wont permanently damage your eyes, but it could give you a headache. cheap sunglasses could also not give your eyes the UV protection they need. Thuis may resolve in damage to the eyes.
"filters"
Cut and faceted gem-quality diamonds reflect and refract all available light, by design. Some say they glitter.
