What are the effect of sunglasses?

Sunglasses protect the eyes from harmful ultraviolet (UV) rays, which can lead to cataracts, macular degeneration, and other eye conditions. They also reduce glare, enhancing visual comfort and clarity, particularly in bright conditions. Additionally, wearing sunglasses can help prevent squinting, which may reduce the risk of developing wrinkles around the eyes. Overall, they are essential for maintaining eye health and comfort during outdoor activities.
