The ortho-k lenses are overall a magnificent product. I never needed to try the ordeal of the glasses sitting on my nose dancing in front of my eyes and making my eyes stifling.
The staff at the office are magnanimous with a great sense of humour. At first the product isn’t the most comfortable thing to be in your eyes, but soon (about 1-3 weeks) you will get used to it and have no problem wearing the product. My overall experience with the ortho-k lens is positive.
