When its turned off, you can let your device sit in direct sunlight exposure without the objective cap for as long as you want to, noting is going to happen.
Aviod direct exposure to bright light, such as car lights, lasers, explosions, fires – if you see bright light during the nighttime simply turn your device other way.
