The answer is 'SUNGLASSES'.
Sunglasses are a form of protective eye wear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. They allow wearers to see into water when only surface glare would otherwise be seen, and eliminate glare from a road surface when driving into the sun. Sunglasses offer protection against excessive exposure to light, including its visible and invisible components.
