Some tools that use lenses to refract light include cameras, microscopes, telescopes, and eyeglasses. These optical devices employ curved glass or plastic lenses to focus and manipulate light, enabling them to magnify images, bring distant objects into focus, or correct vision problems.
Lenses do not reflect light; instead, they primarily refract it. When light passes through a lens, its speed changes due to the lens material's optical density, causing the light to bend. Convex lenses converge light rays to a focal point, while concave lenses diverge them. Some light may be reflected at the lens surfaces, but the main function of lenses is to manipulate light through refraction.
Water, gasses. Any other medium that has a different "n" value gives rise to a bending of light.
Ray-Ban's G-15 lenses are some of the darkest lenses available from the brand. These lenses provide excellent protection from bright light and glare. They are a popular choice for outdoor activities and driving in sunny conditions.
Projector lenses work by focusing light emitted from a light source, such as a lamp or LED, through a series of optical elements. The light passes through a series of lenses that converge and direct the rays to create a clear image on a screen or surface. The design of the lenses, which can include convex and concave shapes, helps to adjust the image's size and focus, ensuring it is sharp and correctly proportioned. Additionally, some projectors use zoom lenses to allow for image size adjustments without moving the projector itself.

Some tools that use lenses to refract light include cameras, microscopes, telescopes, and eyeglasses. Lenses in these tools bend and focus light to produce clear images or magnify objects.
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.
Eyeglasses primarily refract light as they bend it to focus properly on the retina. Some reflection may occur on the surfaces of the lenses, but the main function is to refract light to correct vision.

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.
Some objects that can refract light include lenses, prisms, water droplets, and glass. These objects have different refractive properties that cause light to change direction as it passes through them.
Some everyday objects that have lenses include eyeglasses, cameras, magnifying glasses, binoculars, and microscopes. These lenses are used to bend or refract light in order to correct vision, focus images, or magnify small objects for better visibility.
All see-through materials. Glass is well known. Water also refracts light. Diamonds refract light a lot. Even air refracts light a little.
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.
Water, gasses. Any other medium that has a different "n" value gives rise to a bending of light.
Some examples of diverging lenses include biconcave lenses, planoconcave lenses, and concavo-convex lenses. These lenses are thinner at the center than at the edges, causing light rays passing through them to diverge. Diverging lenses are commonly used in combination with converging lenses to correct vision problems.
When a lens loses its elasticity with age, it becomes less able to change shape and refract light properly. This can result in a condition known as presbyopia, where it becomes difficult to focus on close objects. In some cases, this can be corrected with reading glasses or contact lenses.
