Edit: After using the lenses for a while, I found that not all of them were in the correct position when taken out of the packet. To check, simply hold the lens up and see if it curves up correctly, resembling a bowl shape, or if the edges slightly turn outwards. If they are not positioned correctly, just turn them the right way, rinse with saline, and they are ready to be inserted. If the lens feels uncomfortable, it's worth checking if it is inside out before inserting it. Apart from these minor issues, I must say that the delivery was fast, the price was good, and the lenses are comfortable once they are inserted properly.
