I have the Kamra Inlay and it works. I don't use my reading glasses anymore. It is a luxury to not have to always reach for glasses. Reading text messages, menus, this computer screen, etc,.. whatever it is that would normally require your readers you don't need them anymore. The lighting in the room is a big key factor, but typically if the lights are on you can read it. Dr. McCulloch and the staff at horizon Laser Vision are all great.
