RGP Contact Lenses

Hi, I am interested in RGP lenses. Is it true that they provide crisp vision only when you look straight ahead? Is the vision blurred when you look in other directions or after you blink? Thank you.
Dr Langis Michaud's response:
Dear Mihaela
You are right to say that RGP provides a very crisp and sharp vision, especially if your refractive error is high or if you have a significant amount of astigmatism. If RGP lenses are fitted well, you will be able to see clearly everywhere because the lenses follow your eyes. There is a new generation of RGP lenses, called mini-scleral. They are as large as a soft lens, as comfortable as a soft lens but provides this crisp and clear visual acuity given by RGP ones. They do not move on the eye so there is no visual fluctuation. The problem is that not so many practitioners can handle these lenses and the learning curve to fit them is certainly there. If you are living near Waterloo, ask to have an appointment at University School of Optometry clinic. The same for Montreal in Quebec. Outside of that you can ask your optometrist if he or she is able to fit these lenses or if he knows who can do it in your area. As a last resource, email me and I’ll try to find someone reliable in your area.
Good luck
