The Challenger Deep is the deepest known point in the Earth's oceans, reaching a depth of about 36,070 feet (10,994 meters). **

Deep red light with a wavelength of 670 nm can beneficially enhance color vision by stimulating the cones in the retina that are sensitive to longer wavelengths, particularly the red cones. This can help to improve the perception and discrimination of red and other warm colors, leading to a more vibrant and detailed color vision experience. Additionally, exposure to deep red light can also help to improve overall visual acuity and contrast sensitivity, leading to better overall color perception. **
