Theoretically, the 0.5mm pd difference will not do harm to your eyes. However, you can find some online maker which can process the eyeglasses with your precise prescription just like firmoo.com. Firmoo allows you to enter the right pd and left pd separately while placing an order. Then they will process the eyewear according to your left pd 30.5 and right pd 31.5 instead of just a single pd 62mm. Moreover, the premature wrinkle is nothing to do with your broken glasses. it just a natural thing. Or maybe you skin creases in a long time, and it will cause premature wrinkle. Hope this helpful.
