Cycling issue

Ok, yesterday had the cataract surgery on right eye. Both done and now I need readers. Not sure if I will be able to see my Garmin 945 on the bars have not tried. Then there is the issue of what glasses to wear for night riding since I go sometimes 90 minutes before sunrise. I am thinking the yellow driving glasses. I am mostly concerned about protection of eyes from things but better vision is good too.
Right now I can tell no need to use and prescription glasses to ride just find the best sunglasses. They also make sunglasses with readers in bottom.
Ok forum this is not political question, job, or technical situation I need real world experience and thoughts.
