Hi Lauren, 52 is lens width, 16 is bridge distance, 140 is temple length, not total width. According to the three numbers, this frame is suitable since it's similar to your old one. But it's better to check the total width as well-the distance between the two screws. Total width of this frame is 130mm. Pls click here for more tipshttps://www.firmoo.com/help-p-1.shtml. BTW, if there are adjustable nose pads with your old one, it's suggested to find the same type; otherwise, it may cause discomfort or you may need more time to get used to it. For any problem, pls feel free to start a livechat for faster help.
