Well it can be both sunny Jim it really depends on the context in which you are looking at it. Most sunglasses material will reflect light unless its like maybe some gun metal black. It also depends whether its in the sun or not.In some types of sunglasses may also refract light. Depending on the material of course.

Yes, sunglasses are examples of refraction. The lenses in the sunglasses are designed to bend or refract light in a way that reduces glare and protects the eyes from harmful UV rays.
No. Sunglasses are not waves.
Moreover, even the LIGHT that passes through sunglasses is not refracted,
unless the sunglasses are manufactured to a prescription.
No. A straw is not a wave.
However, if a straight straw is partly immersed in water and appears to be bent,
then THAT is an example of refraction of light.
Sunglasses primarily work through absorption and polarizing light to reduce glare. They do involve some refraction when light passes through the lenses, but this is not the main mechanism by which sunglasses reduce glare.
Some examples of light refraction in everyday life include the bending of light in a glass of water, the rainbow effect seen in a prism, and the distortion of objects when viewed through a magnifying glass.
Light, sound, and water are common examples of materials that can undergo refraction. Essentially, any wave—including electromagnetic, acoustic, and water waves—can experience refraction when it passes from one medium to another of different density or composition.
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
One common refraction example in science is the bending of light as it passes through different mediums, such as air to water or glass. This phenomenon is often observed in lenses, prisms, and optical fibers. Another example is the refraction of seismic waves as they travel through layers of the Earth's interior, helping scientists study the Earth's structure.
