However, keep in mind that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Frequent reapplication of a broad-spectrum SPF 30+ sunscreen is vital every two hours or directly after a swim or an outdoor workout. Note! The Sun's UV radiation gets intensified with the reflection from sand and water.
