Sun exposure can harm the eyes at any age, not just later in life. Ultraviolet radiation from the sun can contribute to cataracts, damage the cornea and retina, and cause short-term pain (photokeratitis). Wearing sunglasses that block 100% of UVA and UVB rays greatly reduces this risk and also cuts glare, helping you blink less and avoid eye strain. Because children spend a lot of time outdoors and their eyes are still developing, protection is important for everyone, young and old. When selecting sunglasses, look for UV 400 or 100% UV protection, and consider wrap-around styles for better coverage; polarized lenses can reduce glare but do not replace UV protection. Some UV can reach the eyes even indoors or near windows, so sunglasses are helpful whenever sun exposure is present. The option that limits protection to only outdoors isn’t accurate, and restricting protection to older adults ignores the benefits for younger people. So, yes, everyone should wear sunglasses in the sun.
