Question

my perscription is 8.4 but i want these cool circled contacts that have a base curve of 8.6. is it okay just to get them. I mean does it relaly make that much of a difference .2?

Answer 1

Going from an 8.4 to an 8.6 in the SAME brand doesn't work...but in a different brand, it might work.

You have about a 50/50 chance that they will fit right.

It depends if you were at the high end or the low end of the measurement that determined the 8.4...which is something you wouldn't know, and we can't guess at.

Answer 2

Sometimes it does make a big differecnce.  The base curve is how the contact fits your eye and rides on your cornea.  If the base curve is not the right size, your contacts may move more than norm ally do and may not feel as comfortable.  It may work, but understand why if it doesn't.
