- Loss of central vision (solar retinopathy)
- Distorted vision
- Altered color vision
The site recommends that if you experience any of these symptoms after viewing a solar eclipse, you should immediately seek care from a licensed professional like an optometrist.
Now, it's not a total "you're going blind" sentence, as one 1999 study in the United Kingdom showed following an eclipse. Of 45 patients with possible solar retinopathy who reported eye problems, 12 later reported that their vision had returned to normal six months later. However, the counterpoint to that is the case of Louis Tomoski, a Portland man who looked at an eclipse in 1963 with his naked right eye. He has been partially blind for the last 54 years, according to local news station KPTV.
“Oh 20 seconds probably, that’s all it took,” Tomososki said. “I’m glad I didn’t go 40 seconds, it would have been even worse.”
