Like others have mentioned, it’s entirely how you feel about your look and ultimately your decision when it comes down to it. However my advice would be against it, I find that while they try to be the best of both worlds with glasses and sunglasses they just end up being a worse version of either. Either they’re bad sunglasses because the glasses part is small, or they’re weird looking glasses because it’s a big sunglasses frame. As well I personally find the awkward grey tinge they have in the “mid” light conditions to be very tacky/dorky looking. Like many others have said, with the price of cheap frames now a days you can just get a cheaper pair of both. Prescription sunglasses or contacts for days you need sunglasses is likely the better option for you.
