Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance. Before exposing yourself to the Sun, apply sunscreen with 30 SPF or higher. This safeguards against sunburn and its harmful radiation. Be attentive! The UV exposure is heightened with reflections from sand and water.
