Poor glasses photographer

It's just influential, and it's basically nothing in the way.

If the degree is not high, you can adjust the diopter in front of the viewfinder, so you can work without glasses.

Another way is to wear a fisherman's hat to block the messy light from slipping into your eyes.

Baseball caps with hard brim sometimes have a bad effect, because the use of flash > 90 can't prevent the brim from turning backwards when working. At this time, when there is light influence, things that slip into the eyes can't be completely blocked.
