The pool screen is comprised of very tiny mesh and provides no sun protection. You'll get a tan below it. It simply shields you and the pool from pests, which is especially useful in the evening. However, because it's made of mesh, you can see through it which means you will be able to see your body even while underwater. The best way to avoid getting a sunburn while at the pool is with caution. Don't go outside without protecting yourself first. Even if you feel like you are not going to burn, it's still important to protect yourself. Wear sunscreen every time you go out into the sun. Avoid being outdoors during peak hours when the sun is most intense. Be sure to wear appropriate clothing too. If you plan to be in the sun for an extended period, consider wearing a shirt with a collar or a tee-shirt with prints on them. They will help to prevent you from burning more visible skin. If you do end up with a sunburn, try not to worry about how dark your skin becomes. A lot of people think that a darker skin color means they're doing a better job of protecting themselves from the sun, but this isn't true at all. The only thing that matters is how much damage you might be doing to your skin by staying out in the sun too long. Try not to stay out past 6 o'clock.
