Yesterday's solar eclipse may have permanently damaged up to five per cent of viewers' eyes, according to an Australian eye expert.
Doctor Bill Glasson told newscom.au up to five out of every 100 people who watched yesterday's solar eclipse would have permanent eye damage.
"They will have a blind spot, or black spot, in the middle of their vision when they wake up," he said.
"If it persists for more than a day certainly it will have done some damage.
"Some may find they have a permanent burn scar on the back of the eyeball and visual loss for the rest of their life."
