Hi Joyleena, the ordering process is very simple. If you have a prescription, you can find a frame you like first. Once you select a frame you will enter/upload your prescription and PD, and then go through the lens selections to pick the options you want on your glasses. Last is check out. Check here for step-by-step guidance: https://www.firmoo.com/help-p-42.shtml. Also, please note that Sunglasses can only be used for distance, not for reading, bifocal or progressive. However, common or regular frames with a photochromic lens, tint lens or polarized lens can also be used as sunglasses. Please check this link for more information: https://www.firmoo.com/help-p-107.shtml. I hope this is helpful.
