UV and glare are not the issue. The issue is whether or not the pitcher is wearing something which serves as a distraction to the batter thus giving the pitcher an unfair advantage. This is just like the multi colored glove rule and the batting glove rule.
I see nothing in the rules which would prevent the use of sunglasses per se. My only issue would be if the sunglasses themselves were highly reflective and causing a distraction problem as a result.
