Some of us, (ME), eyesight ain't what it used to be...having said that I only need glasses to read or see small print. I have been using these for some time and they are helpful and thought someone else may have the same issue as I.... I place one of these lenses more or less under my left eye as that is the side my GPS/Radio is on...that way I can look at either and really not take my eyes off the road. I have these on my Arai shields, one for the dark smoke and one for clear at night...hope someone finds this helpful.....
