Yes, you can use a headlamp for reading. There are a few things to keep in mind, though. First, the light from a headlamp is often brighter and more focused than the light from a traditional lamp. This can be good for reading, but it can also be a bit harsh on the eyes. Second, headlamps are often worn on the head, which can make it difficult to keep the book in one hand and the headlamp in the other. You may need to experiment a bit to find the best way to hold both the book and the headlamp.
