SIU Eclipse Glasses are available at the University Bookstore in the Student Center.
From NASA, “Eclipse 101: Safety” web page, https://eclipse2017.nasa.gov/safety:
“Looking directly at the sun is unsafe except during the brief total phase of a solar eclipse (“totality”), when the moon entirely blocks the sun’s bright face, which will happen only within the narrow path of totality.”
“The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” (example shown at left) or handheld solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun.”
