infrared
Infra-red light. Invisible to human eyes, but relatively easy to generate, focus, and detect.
Infrared light is used in industrial, scientific, and medical applications. Night-vision devices using infrared illumination allow people or animals to be observed without the observer being detected.
It depends on what the vision 'problem' is. Convex lenses are used to correct short-sighted errors, while concave lenses correct long-sighted problems.

A night vision monocular is typically used for enhancing visibility and observing objects or activities in low-light or dark environments, providing clearer vision and the ability to see in the dark with the assistance of infrared technology.
Red light is often used in night lighting because it does not affect the chemicals in the "rods" of the retina, which are used for low-illumination vision.
Yukon night vision devices are, as the name suggests, used for seeing at night. They are also useful for seeing in the daytime if adapted with pinhole lenses, or in any low-light environment.
Night vision optics are pervasive all over the world. The infrared glasses are available in stores all over the nation.
