I never thought that too much light would be a concern. I do just fine wandering around outdoors with eleven candle power from a Streamlight Stylus most of the time. Throughout the winter, reading has been an issue, and having enough light is the most common issue. Being the cheapskate that I am, I figured that using the kerosene fueled Coleman 237, even when preheated with methanol, was cheaper to feed than the white gas 228F. We flick on the 228's like a switch, but the kerosene lanterns requires a bit more fussing to get fired up, so regular practice is good. The big issue this evening was that I kept seeing white spots before my eyes. I couldn't avoid glancing at that 500 candlepower mantle. I needed a shield. The aluminum reflector that I have on one 228F will not allow enough light to shine out onto the book, and is best at just keeping the lantern from blinding me as I return from the woodpile. The solution turned out to be a simple one. Just a piece of paper over the bail. Plenty far enough away from the heat to be safe, but also far enough away to allow light to illuminate my book, without blinding me when I looked up. Works great, and with the paper clips it stayed put in some heavy winds. Definitely a First World problem, this too much light thing.
