Staring directly at the sun is never a good idea, during the eclipse, it was worse. The partial darkness made it easier but it was still a very bad idea.

It's hard to believe that eye damage could happen from looking at the eclipse without protective eyewear in just a fraction of a second, according to Ralph Chou, a professor emeritus of optometry and vision science at the University of Waterloo, in Ontario, Canada in a recent article at npr.org.

Today (8/23) is when you are going to start experience symptoms of eye damage from starting at the eclipse. Often, you won't feel anything happen but you will start to have problems with clear vision. It is imperative that you get to a doctor to have your eyes checked. As with most any medical issues, catching problems early is key to recovery. However, according to Chou, full recovery from this type of injury isn't a guarantee.

This kind of vision loss can get better over several months to a year. But about half the time, it's permanent. -Professor Ralph Chou
