Weather permitting, Washingtonians soon will get a good view of a full eclipse of the sun — not the whole thing but a good chunk. Here’s hoping that all viewers of this much-anticipated astronomical event take due precautions so they don’t damage their eyesight.
Residents around the nation’s capital can expect to see an 81 percent blockage of the sun at the peak of the Aug. 21 eclipse, not the full solar cover or “totality” that millions of Americans are planning and traveling to view in peak spots that fall in a 70-mile wide swath across the country from Oregon to South Carolina.
Be warned: Don’t think just because the sun overhead is mostly blocked that it is safe even then to stare upwards with unprotected eyes. That might leave a careless viewer in the district with crescent-shaped burns on the back of the eyes, says a vision expert and longtime aficionado who says he has seen 19 eclipses.
