New old glasses or old new glasses

I really hope this will not be an unlucky third time for me. Twice already, I have had to replace the lenses on my spectacles because twice, I broke them. Put it down to clumsiness on my part. The first time I broke my glasses, I had perched it precariously on the edge of the bathroom sink. The second time, my hands went wild and I accidentally hit my glasses. Naturally, it flew off my face. So this is the fourth pair of lenses on the same spectacles frame. Wish me luck; I need it for my spectacles!
