I got my wife an adjustable spotlight for reading with a controllable brightness this Christmas and she loves it. We usually use it while we’re on the couch and I’m watching TV, but it can focus the light down to a small enough spotlight that it doesn’t even register in my perifieral but still lights the book she’s reading plenty bright enough. It might not be the best solution to use in bed, but it was a lot cheaper than a kindle. (Which she has and doesn’t use)
