Query: Mayans with welding helmets

Along with the 53-1 (one returned the book) suckers who have read this book it is all based on sunspots that Mayans supposedly used to make their famed stone calendar and predictions.I only have one question? How the hell did the Mayans look at the sun without protection??? Did they close their eyes and looked?This is a scientific phenomena and it is called GUESSING!!! In case ya didn't know!
