Problem with transitional glasses is we are not allowed to have them any were on the job at any time. So then you have more to carry.
transitional glasses have been proven to change colors of lights and few other issue They were band last year. They had been band before they lifted it after the claims new one had no problems but band was back in 6 months.
Some type of sun glass are also band and they do check them.
I have a pair of glasses that have interchangeable lenses, which I keep the spares, both yellow and clear, in a small pouch. I bought them quite a few years ago, which means "I don't remember where" LOL.
