The Nyos Coral Viewing Glasses are specialised eyewear designed for aquarium enthusiasts and marine biologists to enhance the viewing experience of coral reefs. These glasses typically use a colour-correcting lens technology that filters out specific wavelengths of light, allowing for a clearer and more vibrant view of the corals' natural colours. They are particularly useful in aquarium settings, where lighting conditions can distort the true colours of corals, making these glasses a valuable tool for both hobbyists and professionals in marine biology.
