If you've never tried these yellow driving glasses before, be prepared for a surprise at just how well they work.
To be honest, when you first put them on you probably won't notice a great deal of difference. Things do look a little different of course, but you likely won't think that your vision has been improved much, if any.
The really noticeable benefit will be after you've been driving in the dark for some time. After a long night drive, you'll be amazed at just how little eye strain you experience.
You have to try them to believe it I guess, but they are pretty cheap these days, so it's not like a big risk.
