actors and stars did have a great problem back in those early days with Klieg lights. We had this Klieg light eye problem. We used so much exposure and light, and some actors apparently became affected by it. Believe me, it can be extremely painful. People at that time thought it came from carbon dust floating in the air. Actually, it was from ultraviolet light, and there is now a law that you must not have these lights on without a glass over them. Just a plain piece of glass would have taken care of the problem, because it cuts out the ultraviolet. Now it’s a state law, or a law everywhere,
