I also went prescription sunglasses. The first pair were Action optics, which were very good but lacked side shields. So light in from the side was a problem.
Now i have a pair of Maui Jim prescription glasses and they are very good and with the frames i have i do not have a problem with light coming in the side
The only drawback is the price they are not cheap but they will be what i will replace them with when i get another pair.
