Why do glasses look dark in shadows?

Answer 1

Glasses appear darker in shadows due to the way light interacts with the lenses and the surrounding environment. In shaded areas, there is less direct light, which can cause the lenses to appear more tinted or darker compared to when they are exposed to brighter light. Additionally, some sunglasses or tinted lenses are designed to reduce glare and enhance contrast in bright conditions, making them look darker in lower-light situations.
