Bamboo wood eyeglasses combine eco-friendly style with lightweight comfort, but their UV protection depends on the lenses, not the bamboo material. Lenses with UV400 rating offer nearly 100% UVA and UVB protection, comparable to regular glasses with high-quality lenses. Polarization enhances glare reduction but must be paired with UV protection for eye safety. Frame design and lens coatings also influence overall UV defense.
