The Eyeglasses Method
If you wear glasses, you may have already thought of using them to focus sunlight, instead of a clunky magnifying glass.
Once again, objects that you carry every single day are the best tools to master for survival purposes, because you may not be able to get to your stash of high-dollar fire starters when you really need them.
The eyeglass method works just like the magnifying glass method, though it takes a little experimentation to find the idea focal point. Prepare your tinder, then use your glasses to focus sunlight onto the tinder.
TIP: If you have any paper with large sections of black ink on it, these heat up faster than the light colored sections.
