MaxusomegaYes, you are buying just the frame. Get a prescription for your lenses from your optometrist/ophthalmologist, and then take the prescription and frame to a optician to be filled. Note that the optician may charge you a little extra for using your frame rather than buying a frame from the optician.
I'm unsure of which one to go with, both seem nice but I have a hard time choosing. If any of you could help me choose I'd appreciate it. Also any reason as to why it is so cheap now?
