I wear toric contacts lenses & my diameter on them is 14.50 if I had a contact of diameter of 14.00. Could this cause my contact to slip about 90 degrees out of vision?
It would fit differently, because the diameter of a lens is related to the back curve, and if you alter one parameter it alters the other. A small diameter can make the lens flatter and therefore it can become less stable. On the other hand it may fit just as well! Your contact lens practitioner is there to fit you with the best possible lens, and if you want to change the lens you are wearing for another make, you need to be refitted to ensure that the lens is physically and physiologically suitable for your eyes.
