Yes. I use something similar, and they do help. Though don't expect miracles.
Mine date from the eighties, when I was taking part in some colour vision research, and the researcher mentioned that colour discrimination could be improved by using selective filters. So then it was down to a friendly optician, a set of stock filters and the Ishihara test, and finding which worked best. The one that did improved my colour vision from appalling to poor, but even that is definitely an improvement.
Ever since then I have colour-matched the filter when getting a new set of glasses, and whilst I suspect there has been a bit of drift over the years and my glasses aren't as effective as they used to be, they are still better than my colour vision without.
