Using your Alton Fresnel Lens is a breeze. To start a fire, just hold the lens under the sun and focus the light onto some dry tinder until it catches fire. For reading a map, simply use it as a magnifier to make the small details clearer. When removing a splinter, position the lens over the area to get a better view. Remember to keep the lens in its protective sleeve when not in use to prevent scratches. Since it's made of PVC and is waterproof, you don't have to worry about a little water. But avoid exposing it to sharp objects that could damage the lens. There's no special maintenance needed, just keep it clean and dry, and it'll serve you well for a lifetime thanks to the warranty.
