August 21's total solar eclipse will be the first total solar eclipse in 99 years to be seen across the entire country . While it's exciting, looking directly at an eclipse can cause permanent eye damage or blindness, according to NASA .
To prepare for this, Kottke put together a guide on what to buy to enjoy the eclipse without going blind, including items like solar eclipse glasses, sunscreen, pinhole viewers, and binoculars (be sure to put solar filters in front of them when you're using them).
The guide is geared towards beginners who aren't willing to spend tons of money for fancy equipment but who are enthusiastic about seeing the eclipse. The guide also recommends buying these items as soon as possible because prices increase as we get closer to August 21.
