There are LOTS of different options for making solar eclipse viewers.
So, even if you can't find those hard-to-track-down glasses, you can still safely look at the sun on Monday!
Why it’s dangerous to look at the eclipse with your naked eyes:
The darkness during an eclipse can override the natural tendency to squint and avert the eyes, increasing the amount of ultraviolet radiation landing on the retina and making it more likely that you'll sustain eye damage. Your eyes can sustain damage even if only a small sliver of the sun is visible. The cornea focuses sunlight on the retina and scorches it, and because the retina has no pain receptors, you won’t know what damage has been done until it's too late. MORE INFO HERE
