I ordered the progressive lenses, why is there only one ADD value on my prescription? Stefan November 27, 2019 14:58 Updated Follow The reason behind the only one ADD value progressive glasses is that it applies to both lenses. Related articles I just placed several orders. Can I combine the shipments? The ADD of progressive just have one side, but I need both sides? Where can I get my prescription?
